Bitcoin's Value Plummeted Overnight and No One Knows Why (slate.com)

Jacob Brogan, writing for Slate: While the Western Hemisphere slept, Bitcoin plummeted. Just after midnight Eastern Time on Friday, the cryptocurrency was valued at a little over $15,000, on the digital currency exchange Coinbase. At that point, it was already well below the $19,783 all-time high it had hit the week before. Over the course of the night, Bitcoin began to decline erratically, occasionally spiking but following a general downward trend. Around 9:22 a.m. Eastern, it hit a temporary floor, valued at a mere $10,400. By that point, it had declined more than $6,000 from its short-term peak the morning before, having lost more than one-third of its value. Bitcoin wasn't the only currency hit by a sharp drop. Tech Crunch's Jon Russell reports that most other prominent cryptocurrencies also fell, including Ethereum, Litecoin, and Bitcoin Cash (which is, confusingly, separate from Bitcoin proper). As Russell notes, it's hard to say why this is happening, "in the same way that nobody knows exactly why bitcoin's price has [shot] up from a touch under $1,000 at the start of the year."

      Using bitcoin as currency is about the same as using traditional stocks as currency.

      I really think bitcoin has no real value outside of providing temporary peaks and valleys to trade between. Using an unstable commodity as a measure of trade-worth is far more complex for businesses to adopt at scale, which pretty much relegates it to the small guy looking to move small amounts of currency discreetly.

I wouldn't necessarily be happy about this if I had a bunch of money in a bank account, but most of my money goes towards child care home improvements, and a mortgage.

      In the long term, it would mean that employers would have to pay their employees 100x as much to get them to do the same work, as well as goods and services costing 100x more, and within a year this would lead to people paying roughly 100x higher taxes.

      Paying 40% (or whatever %) of your income to the government in taxes is independent of the value of 1 unit of local currency.

I simply need to convert some assets to USD just prior to paying my taxes (either in april or every 2 weeks). It would be theoretically no different than if the US government only accepted bitcoin as payment for taxes.

      There certainly is speculation, in bitcoin. But I think bitcoin is actually more similar to gold than USD. The supply of USD is controlled by an authority. If the price of USD is too high for you to "buy" you don't have an option to make your own USD as a check on the price. If the price of gold gets high enough, at some point it becomes cost effective to start panning for gold, and if the price drops it stops being cost effective depending on how efficient your method is.

      It's possible for the price of bitcoin or gold to drop to 0, but for the time being there is quasi a cap to the price of bitcoin which is the cost of mining. It makes no sense to buy a bitcoin for $20K if it can be mined for $10K of electricity. So $10K becomes the new cap (sortof)

      There is the issue of mining difficulty increasing as more blocks are found which can (And I think clearly did) drive this cap higher (so I guess it's not a real cap in that it's not static), but it is a cap in that the market couldn't really bear a $1M bitcoin, unless there was a lot more mining happening.

  22. Maybe Short Selling? by ytene · · Score: 4, Informative

    For those not familiar with either the term or the practice, here's a primer:-

    Imagine you think that Bitcoin is in a bubble and hugely over-priced. All it would take would be a sharp pin to burst the bubble and the price will plummet... Well, good for you if you don't have any in your portfolio, but how can you use that to make a shed-load of money?

    You sell short in the hope of starting a run. Here's how it works. You go to the market and you sell say, $100,000,000 of Bitcoin that you don't actually possess... Markets will allow you to do this, as long as you settle all your accounts by the end of the current trading period [i.e. by market close on the day]. So what happens is this:

    You have no cash to buy, and no Bitcoins, but you "sell", $100,000,000 of coins in to the market at say 20% below the currently trading price. Let's keep the numbers simple - imagine the prevailing price was $20,000/coin and you sell for, ooh... $16,000, which is the 20% drop point. The sheer size of your transaction - perhaps done because you've seen a couple of other big sales do the same thing - spooks the market. Suddenly all the traders who have been buying in to the currency are worried and they want out as quickly as possible. They start to offer their holdings for sale at steep discounts, each sale taking place way below the buying price.

    In no time the price of Bitcoins falls through the floor... Everyone wants to sell, nobody wants to buy. Except, perhaps, the suckers who had "buy orders" programmed into their trading platforms if ever the price was "foolish" enough to dip below their target price. Suddenly all those folk with automated buy positions get their trades executed, even while the price continues to tank.

    You watch the price plummet. $19,000, $18,000, $17,000, $16,000, $15,000. Eventually it hits $14,000 and the "dead cat bounce" starts - the price starts to look soooo stupidly attractive that more nuanced traders begin to buy back in. The price rallies. You buy enough coins to cover the "sale" you made at the beginning of the day. Except that you "sold" for $16,000, but you bought back in at $14,500...

    Now let's do the math and figure out how much you made [before transaction fees]. You "sold" $10,000,000 at $16,000 each, which means that you sold 625 coins. Then the price dropped to $14,500 and you bought 625 coins to cover your earlier sale. But because you only had to pay $14,500 for them, you actually pay out $90,625,000. So you've made $9,375,000 with "Other People's Money" - all in a single day.

    Congratulations, you've just passed "Banking 101"....

    Oh, and for those who read this and think, "That's all well and good in theory, but it would never happen in practice..." I'd remind you that roughly 20 years ago, "Black Wednesday" happened, which absolutely devastated the value of UK Sterling on international exchange rates - and in the process made George Soros, who bet "against" the Pound in *exactly* the way I've just described here, a billionaire.

    Until the practice of "short selling" - what I've just described in this post - is made illegal, there is *nothing* to stop this happening with Bitcoin, or with any other traded commodity. Bitcoin is no longer operating like a currency [if it ever truly did], but is now operating exactly like a "bubble" commodity, just like the dot-com boom, like antique cars, like works of art, like vintage wine.

    It's difficult to know for sure, but this event has all the hall-marks of someone attempting to burst the bubble and make a killing. I reckon if there was some short selling in this window that someone might have made a noteworthy profit, but unlikely what we saw George Soros make. Whoever it was, they'll get it right next time...

  24. Rapid trading needs a miner insider by nicolaiplum · · Score: 5, Interesting

    Selling a lot of BTC, quickly, and more importantly reliably, needs the cooperation of bitcoin miners to process your transaction quickly, ahead of others, instead of waiting until... whenever.

    So, look who processed all those BTC sale transactions and how they are connected with the sellers.

    Clearly, BTC trading benefits from insiders because it is so illiquid.

  26. coinbase added BCH, margins and interest, exits by FeelGood314 · · Score: 4, Interesting

    Four things happened starting on Tuesday. Coinbase added BCH, margin accounts and interest became unsustainable, margin calls, exit strategies.

    Coinbase added support for Bitcoin Cash on Tuesday. They also gave everyone 1 BCH for each BTC you had at the time of the split. This should have flooded the market with BCH and driven the price of BCH down. Also the sellers of BCH should have invested in other currencies and pushed those prices up. The opposite happened. News that coinbase was accepting BCH actually pushed BCH's price up and the shift to BCH caused other currencies to fall.

    Most of the trading is now automated trading. You can also buy on margin. However the margin has a 1.5% interest per day. Then funny things happen. If someone borrows 1 BTC and shorts it, and then buys an equivalent amount of 10 other more volatile coins using that money they could cover the interest. For the past 2 months this worked really well. Most smaller cap currencies have gone up more than BTC by more than 1.5%. It seemed like low risk investing. People treat crypto like the stock markets treat stocks assuming that having 100 different stocks has less variability than 1. Unfortunately like the stock market, there is a high level of correlation in price change.

    Now after Tuesday, people who had margin accounts had to top up their margins. This caused a slow sell but the interest rates made borrowing for more than 3 days difficult so starting late last night a lot of people had no choice but to sell.

    Exit strategies - eventually everyone has to actually use their money. I know a lot of people who have made 10x their investment. Their exit has been if it falls 30%, I sell 50%. So if they put in 100K, they had 1M yesterday, 700K this morning and then sold to have 350K in fiat and 350K still in crypto. You can automate that sell.

    The weird part. There are no natural sellers in crypto currencies. They aren't backed in any meaningful way anymore. After this crash all the remaining people who own crypto are non-sellers. They are greedy and will hold indefinitely. The margin people who had to sell are gone, my friends with exit strategies are out. The only sellers left are people who are moving money between crypto currencies. The prices of most currencies not in the top 10 market cap are going to jump 15% before the day is done. In a week the money will be poring back in and zero money will be being pulled out.

    The reason has been known for hundreds of years.

    But we will never learn that a bubble is a bubble is a bubble.

    Bitcoin is a bit of technology/algorithms that would be useful if it weren't so cumbersome. There are better, more recent, solutions for the same problem, and Bitcoin will fall by the wayside.

    In the meantime, none of these things are actual currencies. It's just people playing chicken pretending there's something to back the "currency" and passing the hot-potato along until somebody gets stuck with it.

    Some day, governments or others that can act as a store of wealth may use similar technology.

    Why the heck did you not just use the national currency of whatever country your store is in?

    Bitcoin is not a currency. It's a payment network, and its properties make it best for transactions between two distant people, i.e. online shopping. If you can meet in person then just use cash.
