back to article China announces ‘crackdown’ on Bitcoin mining and trading

China has again signalled deep antipathy to cryptocurrency, this time calling for a crackdown on Bitcoin mining. Last Friday the State Council Financial Stability and Development Committee, a body charged with managing risk in China’s financial system, issued a statement detailing its most recent meeting and conclusions about …

    BTC is a hyped Ponzi Scheme which its anonymous creators invented out of thin air. It’s the biggest scam. People have finally woken up to this nonsense.

        They don't wake.

        It's like Madoff's Ponzi scheme, it only collapses when the last of the money is spent and the scheme goes from worth billions to worthless, by which time it's too late.

        So an exchange receives X dollars per coin for Y bitcoins buy in.

        The 'value' of Bitcoin triples, and the number of bitcoins mined increases by 30%.

        The exchange has at most X*Y dollars to cover X*3*Y*1.3.

        i.e. less than 26% of the coins can cash out before it collapses, the exchange runs out of money and cannot pay out anymore.

        And they do collapse, because once people realize they cannot cash out of their 'gain' or 'loss', they cut their loss and FLEE. But right up until that point, the conmen can convince the marks they are holding valuable 'assets'.

        Ultimately there is no inherent value in Bitcoins beyond speculation by trading into and out of it. A classic Ponzi scheme.

          Re: Ponzi

          Your line of thinking is mostly flawed, since you may not simply decide to sell your coins for "X" dollars and it be magically executed, depriving other traders from getting any and collapsing the exchange. Most crypto coins like BTC or ETH are essentially "zero sum" games. You may call crypto any scammy name you want, but a Ponzi it is not.

          In an exchange you buy coins *from other users* and NOT from the exchange, unless the exchange is a "user" of itself as well. For someone to buy some, someone has to sell.

          If suddenly everybody wanted to sell, the price would collapse, since now there are a lot of coins for not so much dollars (from users willing to buy them) but in the end <new price> x <amount of coins> is _exactly_ equal to the amount of dollars available from buyers.

          And the exchange, as usual, makes a pretty penny from their share of the transactions.

          In that sense, users would lose a lot of money because they bought high and sold very low (close to, but not equal to zero), but would never get nothing from their coins, barring exit scams, "hackers" stealing the wallets, etc. In the worst case of the exchange not having liquity for that coin, nothing blocks transfer to another exchange where there would be a little value left.

          OK, I will concede the case where the coin collapses so hard that it has _zero_ liquidity, then you will lose exactly the value you "invested" and not one cent more.

          However, if you start "investing" in derivatives, futures and other complex "financial instruments" involving crypto, then you may lose your pants. For example, if you bet that the value would go up and borrowed a lot of money to buy crypto now, and the value crashed, you'd be in deep trouble.

            While the cryptocoins themselves are not necessarily ponzi schemes, they are a different type of problem, a lot of the cyrptocurrency exchanges are ponzi schemes.

            Some of the stablecoins however may well be ponzi schemes. At least their failure to find anyone to audit their accounts doesn't help to allay any fears that they might be.

      Suppose you ran an exchange, converting bitcoins into dollars. People spend their money and buy Bitcoins. But also the number of bitcoins continually increases due to mining.

      So now try to cash out all those bitcoins using the dollars that was paid into that exchange. Of course you cannot, there are insufficient dollars available, you must cash out less than you put in. You must lose your money.

      There is nothing of value inside the bitcoin universe to support those extra coins.

      It could only ever work as long as less money is cashed out than is put in. It has no value to support those extra Bitcoins being mined, they are simply diluting the assets of the currency used to buy into the scheme. It only works as long as more suckers buy into the scheme than cash out.

      It's a Ponzi scheme, with a bit of 'crypto bullshit' added to obfuscate.

      The false belief is that it is inflation proof, yet it inflates. The false belief is that there is a limit supply, yet a new crypto currency comes along every few days. All manner of bullshit to draw in more suckers, but mostly the game is "play to their greed", the classic Ponzi scheme spiel.

        Re: Ponzi

        The exchange is not the source of the bitcoin. People who want to buy bitcoin and people who want to sell meet at the exchange. One pays cash and buys bitcoin and the other sells bitcoin and gets cash. The exchange takes a cut of the cash for its service. If more want to buy than sell there is a shortage and the price goes up to incentivize sellers and dissuade buyers. If however more want to sell the price goes the other way. As there is no physical asset driving the valuation it comes down purely to the buyers and sellers sentiment.

        As such it is in the interest of anyone who holds or mines bitcoins to hype them to create the demand that holds the price up. If no one wants to buy the value would fall to zero so big holders will buy the small amounts needed to keep the price up. This also give people the impression that as long as they hold the price will go back up so they don't sell and the upward price is maintained. What the big holders won't do is buy up everything if the market is crashing. They intend to be out of the market sitting on a big pile of real cash before that happens.

        This isn't how an exchange works (or should work). The exchange matches buyers and sellers for a margin, it never holds the stock.

        In my opinion, the major reason Bitcoins are popular is that they are a method of money laundering that allows criminals to extort ransom from people via lockware etc without getting caught by the police tracing the money.

      You and I and probably most readers do not 'get' BTC

      It is easy to point out that

      - given the price gyrations

      it is not a store of value

      - given the inability to support the same level of transaction flow as a 'real' currency, and that it is not acceptable in a good fraction of the world (china), and that if you try to pay someone BTC in a powercut, unlucky, and that as ~70-80% of mining is in china and therefore open to a 51% attack,

      this is not a currency

      We come from countries where currencies have been pretty dependable for a v.v. long time.

      However if you are from China, or India or Turkey where the currency is not stable, the govt has close controls and at short notice, some types of cash have been redefined as 'not cash anymore',

      you do want something you can anonymously keep and send abroad and pay for stuff that you do not want your govt to know about

      If you are in Europe this generally = drugs and guns - and about 40% of BTC spending - as in buying something that is not another currency - seems to be that.

      In other countries that can be just about anything from spare car parts to artwork to antibiotics - but usually used as a way of evading taxes and other country-specific legalities.

      Is that a good thing?

      It makes me think whoever invented BTC was against the concept of govt and rules and things like everyone driving on the left - or right, but not both

        I don't know about Satoshi himself, of course, but the idea of coin got cranking on the cypherpunks mailing list in the late nineties and explicitly was libertarian. Indeed, the term "crypto-libertarian" arose from such thinking.

      Re: Ponzi

      Certainly a speculative frenzy, but not really a Ponzi scheme as there is no element of misrepresenting investment "profits" which is what Charles Ponzi and Bernie Madoff did. Madoff incidentally caught a 150 year jail sentence for his antics. Ripping off the oligarchs can carry a bit of risk.

      More a "Blue Sky" thing as in selling securities backed only by "the wide blue sky of Kansas". That's been illegal in most jurisdictions in the US and many elsewhere for a century or more.

      Cryptocurrency currently seems currently to have a net "value" of around 2% of the world's annual GDP. In order for its value to increase, it needs to gain even an even bigger share. If its "value" were to disappear back into the nothingness from whence it came, people will surely notice. Some folks will be harmed. Many just bruised a bit. But some will be severely damaged.

      Can "assets" worth 2% or more of the world's GDP simply vanish more or less overnight? Unhappily, the answer is probably yes. Can the world take that in stride? Probably. But what if it grows to 20% or 120% then collapses?

      Some folks -- including the Chinese apparently -- view cryptocurrency as a threat to the world's future financial stability. And they may well have a point. It's perhaps a bit ironic that it's the Chinese rather than the EU or the self-professed leader of humanity, the US, that seems to be taking the lead here.

        That's because US style capitalism is currently based purely on greed and power. It's the American Dream.

        Sadly, the American Dream that everyone can "make good" just by working hard has morphed into Darwinian Survival of the Fittest. Just working hard is by no means enough any more. You need money and power to "live the dream".

    Cryptotransaction capabilities absolutely have a purpose, but BTC is a relatively poor implementation. It was the first of course; and serves as a useful developmental step towards a more permanent system.

    IMHO, buying Bitcoin is purely a gamble. No inherent value means that market sentiment is the only price driver. When China or Musk make public comments, the price reacts violently. Gamble right (or be in the know) and you make money, quite possibly lots of it. Otherwise, you should accept that you gambled and you lost (and if you're not in the know, it's akin to betting against the house).

    Go for an asset backed cryptocurrency and you're more of an investor but still high risk because those cryptocurrencies are still pretty niche and volatile.

    Regulation will probably decide the final fate of cryptocurrencies but if they're regulated and brought more into the mainstream, that's going to change them completely and there'll be a very big sell off as the criminal element heads for the exit.

      "Go for an asset backed cryptocurrency and you're more of an investor but still high risk because those cryptocurrencies are still pretty niche and volatile."

      If you want to invest in an asset, buy a fund that reflects that asset. They're regulated and have to verify they actually have that asset. Crypto doesn't add any benefits there. Crypto only has benefits in theory as a method of exchange, and an asset-backed one usually lacks that fluidity without doing much about the volatility problem.

    About Time

    Bitcoin hadn't appeared on the central government's radar until recently when one interior province banned it because it was using too much power, power that was provided by coal fired power stations. Mining then moved to another where power was cheap due to hydroelectricity. This may have attracted the attention of the central government (China, like other large countries, has regional governments plus a central/federal government so policies can differ from region to region and things can happen without the central government being aware of them or controlling them.) Once it did appear on the central government's radar it was likely to either heavily regulated or shut down since its essentially parasitic, it provides no clear value to a community but parasites off that community's resources, in this case cheap electricity and decent internet access.

    Bitcoin has been described as a Ponzi scheme. People often forget that the original Ponzi scheme was a bona fide way to make money off international reply coupons, exploiting the difference in international postage rates between countries. The problem with it is that there was only a small market for these coupons but the market itself rapidly became an out of control vehicle for speculation. Bitcoin's done the same thing -- as soon as people stopped using it for transactions and started using it for 'investment' it became an object of pure speculation, something that has no social purpose except to con people out of money.

    Grand strategic blunder by Christopher Robin's friends?

    If the above assertions that >50% of mining has been going in China is correct (and it certainly makes sense--the lack of environmental regulation in China is legendary, and they have a large existing domestic market for video cards), then taking control of the miners was a much stronger play, as it give one control over the blockchain. OTOH, government-dominated economies have regular failures which prevent them from effectively managing almost any resource. Still, if any single entity manages to get >50% of the miners, they then own the blockchain & can time severe havoc with the currency.

    I'm confused.

    If a country issues currency, it used to have some sort of physical asset to underpin that currency - normally gold, but it could also be oil or anything else that other people needed and would trade; currency was a more convenient way to move this wealth than physically lugging a ton of gold or 10,000 barrels of oil from place to place - my employer gives me currency that says I have "earned" a specific amount of gold or whatever, I use that to pay the supermarket where I buy my food, they pay the farmer, the farmer pays his suppliers, the currency goes around and around until someone transfers it overseas, or whatever - at some point, someone will call in the "debt" and a tangible asset must be handed over or there may be tears. (Always assuming some politician doesn't sell off all your gold on the cheap to prop up his failing policies, but that's another story...)

    If my supermarket said "Actually Mr AC we don't like those tatty bits of paper you're trying to pay us with" I could, theoretically, go to my bank and swap my tatty bank notes for crisp new ones - we are supposed to be above carting around sacks of gold unless you're a 404 Scammer. If, on the other hand, the supermarket were to say "Sorry Mr AC we don't accept British pounds any more, we want paying in US Dollars" then I need to find an Exchange willing to swap my GBP for USD. If the US holds one ounce of gold for every dollar in circulation and the UK government holds one ounce for every pound then it's a straight one-to-one swap. If the US has 1 ounce but UK .gov has only 1/10th of an ounce then the exchange rate would be 1USD costs me 10GBP (plus the Exchange's commission, etc). If the UK has no gold then the Exchange decides if the UK has sufficient collateral to make it worth swapping my GBP, and at what exchange rate.

    With cryptocurrencies, what assets back up the "value" of the money? If anyone with a computer can "mine" Bitcoin or whatever other cryptocurrency you choose, it has no limit on its availability and it's value will, sooner or later, hit as near to zero as makes no odds.

    What has me confused is, what is the difference between crypto-currency and the Emperor's New Clothes?
