21M or Death

21 Million or Death
Arise…

The supply of Bitcoin is fixed at 21 million BTC, and as a hard coded monetary policy of the protocol, the fixed supply of the dominant cryptocurrency cannot be altered.

Former Google Product Director Steve Lee stated that only 1 percent of the world’s population can own more than 0.28 BTC, due to the fixed supply of Bitcoin.

In late 2017, Chainalysis, a blockchain forensics company that monitors and investigates cryptocurrency transactions, revealed in a research paper that up to four million BTC are permanently lost on the blockchain as a result of theft, loss of wallets and private keys, and the dormant wallet of Bitcoin creator Satoshi Nakamoto, which experts have said is no longer accessible.

Kim Grauer, Senior Economist at Chainalysis, said at the time, that the lost supply of BTC is not taken into consideration by the market cap.That means, the real price of BTC could be substantially higher, as 4 to 6 million BTC are estimated to be lost.

Based on the estimate that the supply of Bitcoin is around 17 million, only 0.8 percent of the world population can own more than 0.28 BTC and less than 0.2 of the world population can own more than 1 BTC.

The 0.28 BTC figure introduced by Lee assumes the supply of Bitcoin to be 21 million, as it divides 21 million by 0.28 and divides the outcome of that by the world population that is 7.442 billion. If the research of Chainalysis is accurate and that 4 to 6 million BTC are lost on the blockchain, the supply of Bitcoin should be closer to around 16 to 17 million

The fact that any investor in the global market can be within the 1 percent of the world population with a $1,830 investment demonstrates that the cryptocurrency market is still at its early phase, and in terms of adoption, market development, infrastructure, and regulation, the sector can still grow significantly in the mid to long-term.

First Time/Small Miner

First time/Small miner reference
for getting started.

If you want to start mining here is what you need… and what you need to know.

This is written for home miners/small farms, but can be used as a guideline for most operations. Use this as a reference for what you need to research, or what questions you need to ask before jumping in.

What you need to mine can be broken down into the following categories:

  • Hardware
  • Electricity
  • Location
  • Internet connection
  • Information

Mining BITCOIN is done exclusively with dedicated BITCOIN mining hardware based on ASICs: https://en.wikipedia.org/wiki/Application-specific_integrated_circuit .

You CAN NOT meaningfully mine bitcoin today with CPU, GPU or even FPGAs. Bitcoin difficulty adapts to match the amount of mining done on the network and has reached levels trillions of times too high to mine meaningfully with PCs, laptops, tablets, phones, webpages, javascript, GPUs, and even generalised SHA hardware.

Even if you combined all the computers in the world, including all known supercomputer, you would not even approach 0.1% of the bitcoin hashrate today.

There isn’t any point attempting to mine bitcoin with CPU or GPU even in the interests of learning as it shares almost nothing with how bitcoin is mined with ASICs and will not teach you anything.

Hardware

Asic Miner:

Here is a list of the companies currently manufacturing Miners for public purchase.

Each one has their Pro’s and Con’s it is up to you to do your research and decide what is best for you.

A few points to consider while researching are :

  • efficiency
  • reliability
  • warranty period/policy
  • power draw

Each company has a different way of handling warranty repairs, depending on your situation and the policy repairs can become cost prohibitive. I will touch more on efficiency and power draw in the electricity section.

• Current list of competitive hardware

Power supply: You will need to purchase a power supply to run your miners. You will find ATX and Server grade PSU’s, the latter being preferred for mining BTC. 

When it comes to selecting a PSU purchase something with a capacity 25% higher than your miner is rated to draw. This will have you operating within the 80% rule.(explained further in the electricity section)

EX. Miner draws 1000 PSU should be able to provide 1250W.

** Many current generation miners are now being manufactured with Integrated PSU. Again do your research to see if your unit comes with or without. Generally you will still need to source a power cable.**

Auxilliaries – Avalon miners require an external controller, 1 per 20 miners. You may have to run additional fans for intake and exhaust depending on your location.

PSU’s can be purchased large enough to run 2 Miners; or the opposite 1 Miner fed by 2 PSU’s. Ensure the PSU you have selected will have the correct amount of PCI-E connectors required to operate your miner(s)

You can also find a large supply of used miners and PSU’s. Again it’s up to you to do your research as these often are a no return transaction.

Electricity

Follow all local codes and regulations

This is the number 1 factor in whether mining is right for you. As discussed with Miners being a 24/7 machine drawing power those costs will make it cost prohibitive for some people to mine. You need to be aware of what your costs/kWh are and run the numbers.

This will be done in a profitability calculator. This is just an example of 1 there are many out there.

( Miner usage in kW ) * ( Hours run per day ) 24 * ( Cost/kWh ) = Cost per Day to Operate

( Ideally less than the FIAT value of BTC mined )

The second part to the electrical requirements of mining is the available service; written for North America.

You will need to figure out the amperage you can spare, what circuits and receptacles you have in place, are you setting up on 220V or 110V. You will need to make sure that you have the right cord end for your PSU to match the receptacle, picking the wrong one can cost you a few days of mining if it has to be shipped.

If you can try and set up on a 220V circuit for 2 reasons :

– You will pull half the amps, and it is more efficient.

– Doing so requires 2 breaker spaces in your panel. Breaker sizing will depend on how many miners you plan to run. Here is the formula for calculating amps.

Watts / Voltage = Amps

Here is where you will bring the 80% rule back into play by sizing the continuous miner load to 80% of the breaker rating. 12 Amps on a 15 Amp breaker, 16 Amps max on a 20 Amp breaker, 24 Amps on a 30 amp breaker.

If/when you increase the amount of miners you are running you may want to look into PDU’s, as opposed to more receptacles. 

Location

This is something that is often overlooked to the headache and frustration of many would be miners. These machines are loud and hot .
You essentially have an electric heater that also uses an industrial fan to keep it from melting itself. This space will need to have the electrical requirements as discussed previously.

So make sure you have a space that is well ventilated with a plan to exhaust heat, and bring in fresh dust free air. I say this as using AC to cool the room will eat into your profits and may even make mining unprofitable.

The noise issue is a consideration you can sort out depending on whats available. (garage, basement, remote building)

Both of these issues can be handled with hosting, which is further explained in the information section.

Internet connection

Some miner setups have the option to use wifi. It is advisable to use a wired connection where available. This will provide a more stable connection and ensure you are submitting the expected amount of shares which is directly related to your payouts.

Please note that mining uses a negligible amount of bandwidth, and will not affect your other internet usage.

Information

You can use this information in this post as a good baseline to get you going. In addition to this you will want to research network difficulty; this readjusts every 2016 blocks to maintain a 10 minute block time on average. While this can go down it generally increases.

Solo or Pool?

You can solo mine but this is essentially a lottery even as a large scale miner. Should you chose this you can check this out as a starting point.

solo.ckpool.org 1% fee solo mining USA/DE 250 blocks solved!

Odds are most of you will join a pool. I will only say that it is in your best interest to mine at a pool that pays transaction fees (miner rewards). Then you will want to consider the fees associated with the pool.

When it comes to these pools you want them to be large enough that they are getting at least 1 block every Difficulty adjustment period. Larger pools will offer smaller rewards paid out more frequently, and vice versa.

Bitcoin mining and the Luck Statistic

Bitcoin Mining and the Luck Statistic

• 0. Introduction

My aim is for any brand new miner to be able to determine just how unlikely any run of bad luck is, and so reduce the overall level of panic amongst miners.

Mining panic has been exacerbated by reports of accidental block withholding attacks, and a stratum vulnerability.

Wouldn’t you prefer to know if your panic was actually warranted? 

• 1. Gambler’s fallacy

For miners who have been around for more than a year or two seen good and bad luck (unless they mine at a “Pay per share” pool, in which case they are not subject to luck at all) and know that it will even out in the long term.

However, every new miner striking a run of bad luck will flail around, looking to escape to another pool that is not having bad luck. This sort of response to random events can be thought of as a type of gambler’s fallacy. 

• 2. Bad Luck lasts longer

Another reason that makes us mis-judge mining luck is that when we mine, we mostly experience bad luck.

In fact if you go to the trouble of working it out, your hours of mining will be about one-quarter good luck and three quarters bad luck. Why? Bad luck takes longer, good luck rounds take much less time. 

• 3. Assessing luck over time instead of blocks

Another mistake made by novice miners is to assume that the extremes of luck will be the same for all pool over any time frame. This is wrong for two related reasons:

The more blocks are solved the closer luck approaches 100%

Because the timeframe for luck to to approach 100% varies depending on number of blocks solved, comparing various pools’ luck over the same time period is invalid. Instead we need to compare luck over similar number of blocks.

• 4. The luck statistic, the Erlang distribution, PDFs and CDFs

I’ll try to avoid terms like “variance” and “median” and “maths” in order to not scare away too many readers, but we do need a definition:

Luck = Mean (expected shares per round / actual shares per round)

Luck statistic = mean (actual shares per round / expected shares per round) 

i.e. Luck = 1/Luck statistic

I would much rather just refer to the ‘Luck statistic’ as luck, but due to our psychological preference to assign luck a scale where bigger is better, we need both measures – “Luck” as a shorthand for “How much am I earning as a percent of what I expect to earn”, and the “Luck” statistic. Just keep in mind the larger the ‘luck’ statistic, the worse the ‘luck’.

The luck statistic is negative binomially distributed, but can be very closely approximated by a known and well understood distribution ( Erlang distribution ) which makes calculating probabilities simpler. 

The approximation becomes more accurate as difficulty increases – think of Euler’s (1 + 1/n)^n approximation to e as the comparison of an exponentially distributed random variable (Erlang distribution shape parameter = 1) and a geometrically distributed random variable (Negative binomial distribution, size parameter = 1, probability = 1/n). 

In case you’re worried about the approximation leading to significant error, at current difficulty you’ll won’t see a probability error greater than 0.0000000001.

Visualising the Erlang distribution:

The PDF is the probability density function, which indicates how probable it is that the luck statistic will be some arbitrary value.  

The CDF is the cumulative distribution function, which indicates how probable it is that the luck statistic will be greater than or equal to arbitrary value.

Both plots illustrate:

The luck statistic tends closer to 1.0 as the number of blocks over which the statistic is averaged increases

Extremes of luck are more likely when the luck statistic is averaged over fewer blocks.

• 5. Managing Income Variance

Luck averaged over more blocks means fewer extremes, so more blocks in less time means as a miner you will experience less variation in payout – but also means that you’ll be increasing the size of pools that are already large.

You can avoid this by adjusting your timescale expectations – try to focus on weekly income, or income per retarget and you’ll be less affected by income variations. Wait about one hundred blocks and income will be around +/- 20% of expected.

Your other option is to mine at a pool that has a pay per share (PPS) reward method, but this has a couple of downsides. The first is that since the pool is smoothing out the income variations for you, if they don’t manage that risk properly they could bankrupt themselves, and leaving you with lost income. The other problem is that since PPS is risky not many pools want to provide it so you won’t have many options about where you can mine.

• 6. How can you calculate the CDF probability yourself?

If you want to manage your expectations without using a PPS pool you need to know what to expect. Not just the reward per share but the typical range of values you might encounter in some time frame. So, how can you calculate the CDF probability yourself? If you have some experience with statistics or coding knowledge can use R or mathematica  or even python, but you can also use the Wolfram Alpha website. By entering the luck statistic and the number of blocks over which the statistic was averaged, you get the lower tail probability of that statistic occurring.

CDF [ErlangDistribution[nblocks, nblocks], luck statistic]

For example, if the luck statistic was 1.1 over one hundred blocks is that quite unlucky or just a little unlucky? Enter: 

CDF [ErlangDistribution[100, 100], 1.1]
The result is 0.84, so for 84 times out of one hundred re-runs of one blocks, we’d see luckier blocks. Not that unlucky – 1 in every six re-runs would be unluckier. 

• 6. How can you calculate the probable luck outcomes yourself?

Rather than assess how lucky or unlucky your pool has been, planning requires you to  estimate how unlucky is could be in future. Let’s say you plan to be able to manage a monthly worst case of 0.999 (one one in a thousand re-runs of the months blocks would be worse), and your expect your pool to solve around 50 blocks in that time.

quantile(ErlangDistribution[50, 50], 0.999)
This results in a luck statistic of ~1.495, or a luck of 1/1.495 = 66.9%

• 7. I need something easier.
Or less statisticky, anyway.

OK, I hear you. My fun != your fun. This chart gives you the expected luck percentage (and it’s all bad luck) for bad luck with a 1/3 chance of that luck or worse occurring (not very unlucky) to bad luck with a 1/10000 chance of that luck or worse occurring (really quite unlucky). Use it to either plan for the future or get an idea of how lucky you’ve been.

For example, my pool solves ten blocks at a luck of 80%, is that really bad? Not really. It’ll happen around 20% of the time (1/5 chance of that luck or worse occurring). Maybe I just want to make sure I can cope with a 1/thousand bad luck run of five hundred blocks (~67.5%).

8. Summary

Variance in income reduces as a function of number of blocks solved.

Variance in income is not a function of time.

Learn how to plan for bad luck, and to check that your pool’s luck is not impossibly bad.

The Laws are Unjust

As we’ve seen over the many years that this rag has been written (and beyond) companies who are able to fund whole teams dedicated to data security have been wholly ineffective at storing that data safely.

With the passage of this new law EU officials are actively putting citizens in harm’s way by irresponsibly trying to force bitcoin users to collect and store each other’s data. This is if you believe that is the actual intention behind this move.

In reality, this move likely serves as a pure intimidation tactic to coerce people to use trusted third parties when transacting with bitcoin.

A heavy handed shove into easily controlled vectors. If too many users are in control of their own private keys, run their own nodes, and are up to date on best privacy practices when transacting it is much harder to stop bitcoin.

And make no mistake, these people want to stop bitcoin at all costs.

They do not want you to be free.

They are quickly losing their grasp of control on the populace and they are moving as quickly as possible to clamp down in an attempt to retain control.

You are not meant to have privacy in their eyes. You are inherently a criminal in their eyes. These people think you are disgusting cattle who needs to be led at every turn.

It does not have to be this way. You do not have to succumb to the madness of these people. All it takes are a few decisions.

Speak up!

Act!

Disobey!

There is a silent majority out there who knows this type of attempted control is inherently wrong.

It is anti-human!

It is evil!

This silent majority needs to begin developing the courage to speak up.

Call out the abject insanity of allowing unelected institutions like the Financial Action Task Force write freedom restricting guidelines that get adopted by governments like the EU.

Learn how to run your own node, how to produce your own private/public key pairs, and how to destroy chain analysis heuristics with privacy best practices.

Make the tyrant’s job as hard as possible!

Disobey!

Stand up and defend freedom in the Digital Age by actively defying their unjust laws.

“If a law is unjust, a man is not only right to disobey it, he obligated to do so.”

It is your duty as an individual to disobey these incredibly invasive and tyrannical “laws”.

If you don’t disobey your progeny may not have the opportunity to. The time to counter punch is right now. Get on it.

The monetary properties of Bitcoin

bitcoin vs gold
bitcoin vs fiat

Bitcoin is a monetary good — a new form of money. As Bitcoin is a money, it must be compared to other monies to consider the comparative advantages of Bitcoin and from that consider further the probabilities of Bitcoin winning ground or not in the competition between monies.

Brief summarization of the monetary properties

Summarization of the monetary properties of Bitcoin compared to precious metals and fiat currencies

As the exhibit above showcases, Bitcoin offers many different distinct and compelling competitive advantages to the alternatives.

These include, but are not limited to:

1. Bitcoin is the first asset in the human history to provide any holder a very sure case of unseizability and censorship- and judgment-resistance for their funds.

◦ Unseizability: With precious metals and fiat currencies, the custodianship is mostly in the hands of trusted custodians that is subject to any intervention by a government or authority.

Bitcoin, with self-custody being orders of magnitude easier than with precious metals and fiat currencies, and access to the corresponding private key of funds being the sole way to access and move funds, no one can seize your bitcoins.

◦ Censorship- and judgment resistance: With precious metals and fiat currencies, the payment clearing for small value transactions can with not much hassle be somewhat censorship resistant if the involved parties are willing to transact in the physical units of precious metals and fiat currencies and to self-custody the funds going forward.

However, with non-small value transactions it is exceedingly inconvenient and costly for transactions of precious metals and fiat currencies to happen in the offline, with physical units and self-custody going forward, leaving the centralized intermediaries as the only option and these are subject to any intervention by a government or authority.

Bitcoin, with the payment clearing involving no centralized intermediaries but instead a decentralized and distributed setup requiring no AML/KYC, the result is that of a the payment clearing process being permissionless, allowing anyone with cryptographic access to funds to move them at their will.

2. Bitcoin provides an inherently apolitical global monetary unit. It is truly border-less, with no recognition of any jurisdictional rules and laws, allowing the jurisdiction of a counterpart in any transaction to be of no relevance.

◦ Fiat currencies are highly political and precious metals are less political than fiat currencies, but still much more political than Bitcoin.

◦ Bitcoin is truly border-less: any bitcoin funds can be accessed anywhere on the planet by having access to information that can even be stored inside a human brain and reliably retrieved at small effort — and, crucially, with no intermediary and no permission required the bitcoin funds can be moved to anywhere in the world with final settlement in the next block.

3. Bitcoin provides scarcity and salability through time characteristics vastly superior to any other monetary options, including fiat currencies and precious metals.

◦ The non-discretionary monetary policy of the bitcoin networking allowing for the asymptotic money supply* of 21 million BTC is built into the literal definition of the protocol. This is a drastic contrast to the arbitrary scarcity of fiat currencies governed by politics.

The scarcity of precious metals is much better than fiat currencies, but Bitcoin with the strictly fixed money supply outperforms any precious metal.

Bitcoin provides any holder a reassurance stronger than any other asset in the world that their ownership stake in the total quantity of Bitcoin on the market will never diluted.

One BTC of 21 million will always be one BTC of 21 million.

◦ Bitcoins are infinitely durable, impossible to counterfeit or dilute, can be stored at no cost and at no degradation.

* By inventing Bitcoin, Satoshi Nakamoto created the first example of a digital good (in this case, monetary good) that is impossible to reproduce ad infinitum, thereby creating the first instance of human history of digital scarcity.

Less talked about it, but perhaps more important, Satoshi Nakamoto with Bitcoin also created the first example of a good being absolute scarce.

Previously, any consideration of scarcity of a good was relative. Any physical good is never absolutely scarce, onlyrelatively scarce when compared to other goods — simply because any limit on a physical goods is a function of the time and human effort put towards producing the good.

Bitcoin, with the asymptotic monetary supply built into the protocol, is therefore the first example of absolute scarcity in a liquid commodity and good that cannot have its fixed quantity of supply increased.

Apollo BTC – A Bitcoin ASIC Miner and Desktop Class Computer running a Full Node

Introducing the FutureBit Apollo BTC

Six CPU Cores. 44 ASIC Cores. 1TB NVMe Based SSD Drive. Quiet. Less than 200 Watts of Power. Made in the USA. This is what the Future of Bitcoin looks like. 

FutureBit Apollo BTC is the world’s first vertically integrated platform bringing the full power of Bitcoin and it’s mining infrastructure in a small, quiet, easy to use desktop device designed for everyday people. 

We have iterated and learned much from our first Apollo product. We realized early on that we focused too much on the mining aspect, and not enough on the software, applications, and services that run Bitcoin. Too many of these services have moved to online centralized websites, and many users have given up on running the core software that powers Bitcoin. 

This must change, as Bitcoin will not continue to be the free, un-censorable, decentralized system it is today if only a few control the mining that powers it, and the nodes that control it. 

At the heart of the new Apollo BTC product is a revamped SBC (Single Board Computer), that is as powerful as any consumer grade desktop system and can run almost any Bitcoin Application natively on the device 24/7. Take it out of the Box, plug it in, power it on, and you are already running a full Bitcoin node without needing to do anything.

Install a wallet of your choice, use any hardware wallet, run BTCPayServer, run a block explorer, run a Lightning Node. All of this is possible with our six core ARM based CPU with 4GB of RAM, and a 1TB NVMe drive that can easily store a FULL non pruned Bitcoin Node. It can power through a Full Node Sync in under 48 hours, which is a record for a device of its class! This is almost an order of magnitude faster than any Raspberry Pi 4 based Node. 

On top of this we have taken our 6 years of experience building ASIC mining devices, and engineered the only American Made TeraHash range Bitcoin mining device that can be silent on your desk, mine Bitcoin in the background 24/7, and only use the power of one light bulb to do it. 

We did this with our optimized PCB design that has carefully placed all 44 hash cores underneath our custom cold-forged aluminum induction heatsink, which draws up to 200 Watts of heat away from the device with our new nearly silent 25mm fan. This results in the Apollo BTC in Turbo Mode being just as quiet as the Apollo LTC in Eco Mode!

Like our previous products, we are super proud that we can continue manufacturing the Apollo BTC in the USA, and are now the only USA based company that delivers Bitcoin ASIC products with a supply chain whole owned in the western hemisphere (no more reliance on Chinese based ASICS, and their willingness to only sell to large farms and the highest bidder). 

OPTIONS

Full Apollo Package: This is our Full Package option that comes with everything you need in the box. The Apollo BTC Unit with our latest controller built in, and our 200W Power supply with power cable. 

Full Apollo Package NO Power Supply: We are also offering the Full Package with no power supply for people that want the plug-n-play experience but have spare 12v ATX power supply. 

Standard: This option is ONLY the Apollo ASIC Miner, with no controller or power supply. Our new hashboard has a micro USB port, and can be used as a USB device. The Full Apollo Node can control multiple standard units through its USB ports. We wanted to give our customers an option to expand their hash power in a cost effective way. If you already have a Raspberry Pi, or Linux/Windows Desktop Computer and a power supply with two PCIE power ports you can also control our Standard unit in this way with our stand alone miner software (please note this setup will be for more advanced users, and the software will be command line based on launch). 

Standard + Power Supply: Same as our Standard unit above, but comes with our 200W Power supply. This is a plug and play solution if you already have a Full Apollo Package. Take it out of the box, plug in the power supply, plug in the micro USB cable to the back of your Full Apollo BTC and it will automatically recognize the second hashboard and start mining! 

  • Compact All-In-One Desktop Bitcoin System (4x6x4in) that mines Bitcoin and any SHA256 based crypto (Bitcoin Cash etc). 
  • Powerful 6 ARM Core CPU with 4GB of LPDDR4 RAM and 1TB NVMe SSD (NOT included in the Standard or Standard + package). 
  • Comes Pre-Installed with a Bitcoin node, and you can install almost any Bitcoin Application
  • Very wide range of operation modes with preset ECO (quiet) mode, BALANCED, and TURBO mode. 
  • 2-3.8 TH/s of SHA256 performance per miner (+/- 5%)
  • 125 Watts in ECO mode, and 200 Watts in TURBO * +/- 10%
  • Can be used as a full Desktop computer with a monitor keyboard and mouse (not included), or through our Web UI
  • Connect almost any peripheral with our USB 3.0 ports, USB C port, HDMI, AC Wifi, and Bluetooth 
  • Clocks and Power is fully customizable by user with easy to use interface
  • Hashboard now monitors both voltage and power draw for accurate measurements*
  • Custom designed cold forged hexagonal pin heatsink with leading thermal performance for the quietest ASIC miner in operation!
  • 1k-5k RPM Quiet Dual Ball Bearing Fan with automatic thermal management with onboard temperature sensor
  • Controlled via local connection on a web browser similar to antminers. You can simply set it up via smartphone browser. No crazy driver installs, hard to use miner software or scripts needed.
  • Two Six Pin PCIE power connectors for wide-range of power draw
  • Custom Designed all Aluminum case
  • Ships with our own custom built 200W 94% efficient PSU and is ready to run out of the box! (Does NOT come with Standard package). 

 Requirements:

  • Router with an Ethernet cable for initial setup OR Monitor with keyboard and mouse
  • At least a 250 watt 12v power supply with two 6 Pin PCIE connector is required (unless you order our packages that come with our power supply). This is the same connector used by all modern GPUs. Please note even standard units NEED a power supply, they cant be powered through the USB port on the full package unit. 

As I am the owner of two of these beauties, that I have on my office as you saw in the photo above, I took the liberty to make Free-Publicity for the FutureBit Apollo Btc Miner.

Trilemma of International Finance

Trilemma of International Finance

The relative value of any two curren-
cies—the exchange rate—is determined
through their sale and purchase on the global foreign exchange market. If government policy interferes with this market by changing the relative supply or demand of currencies, the exchange rate is managed.

The trilemma of international finance, is a restriction on government policy that follows immediately from the interaction of exchange rates, monetary policy and international capital flows.

Trilemma of International Finance

The trilemma states that any country can have only two of the following:

  • (1) Unrestricted international capital markets.
  • (2) A managed exchange rate.
  • (3) An independent monetary policy.

If the government wants a managed exchange rate but does not want to interfere
with international capital flows, it must use
monetary policy to accommodate changes
in the demand for its currency in order to
stabilize the exchange rate.

In the extreme, this would take the form of a currency board arrangement, where the domestic currency is fully backed by a foreign currency (as in the case of Hong Kong).

In such a situation, monetary policy can no longer be used for domestic purposes (it is no longer independent).

If a country wishes to maintain control over monetary policy to reduce domestic unemployment or inflation, for example, it must limit trades of its currency in the international capital market (it no longer has free international capital markets).

A country that chooses to have both unrestricted inter-national capital flows and an independent monetary policy can no longer influence its exchange rate and, therefore, cannot have a managed exchange rate.

Pieters and Vivanco (2016), government
attempts to regulate the globally accessible
bitcoin markets are generally unsuccessful,
and, as shown in Pieters (2016), bitcoin exchange rates tend to reflect the
market, not official exchange rates.

Should the flows allowed by bitcoin become big enough, all countries will have, by default, unrestricted international capital markets.

Thus, with bitcoin, (1) unrestricted
international capital markets is chosen by
default.

Therefore, the only remaining policy choice is between (2) managed exchange rates or (3) independent monetary policy.

If the country chooses (1) and (2), it must use reactive monetary policy to achieve the managed exchange rate.

If the country chooses (1) and (3), it must have a floating exchange rate because it has no remaining tools with which to maintain a managed exchange rate.

Ali et al. (2014), the European Central
Bank (2015) and the Bank for International
Settlements (2015) all concur that cryptocur-
rencies may eventually undermine monetary policy.
