China has lots of rich people, but a fragile banking system, and strict capital controls, meaning it's difficult to get your wealth out of the country. One way rich people get their wealth out of the country is by laundering it through Macau. Mamta Badkar wrote a great explainer of how this works. Basically, your Chinese millionaire gives millions of dollars to a "junket" operator in the mainland. That junket operator then provides them with millions of dollars worth of chips at a casino in Macau.
The millionaire then plays numerous hands of some game probably baccarat then at the end of the session cashes in the chips in Macau's currency, the Pataca.
Then those Patacas are deposited into a bank in Macau, and voila, the millionaire has just escaped China's capital controls, having successfully moved millions outside of the Chinese banking system.
Bitcoin, theoretically, promises an even easier path to do this. Rich person buys a bunch of bitcoins, transfers them to a Bitcoin wallet associated with a financial institution outside of China, sells the bitcoins into some new currency, and then voila. Economist Tyler Cowen wrote a long post about Bitcoin and its potential in China last week:. Right now, you can think of the value of Bitcoin being set in the same way that the value of an export license might be set through bids.
To the extent the shadow market value of the yuan rises, and approaches the level of the current quasi-peg, the value of Bitcoin will fall, by how much is not clear. Or maybe getting money out through Hong Kong or Shanghai will become easier and again the value of Bitcoin would fall. If you are long Bitcoin for any appreciable amount of time, it seems you are betting that the Chinese economy will do poorly and capital controls will remain. Then more people will be increasingly desperate to get more money out of the country.
Or you may be betting that the Chinese use of Bitcoin to launder money will increase due to the mere spread of the idea, through social contagion. Now, earlier I mentioned that the rising price of Bitcoin, rather than being a hindrance, could actually be helpful.
See, while everyone talks about Bitcoin, there are actually a ton of crypto-currencies. The "market cap" is just the price of each coin multiplied by the number of outstanding coins there are for each. Here's a look at the top eight among them.
Now each one of these coin systems are pretty similar, but they have slightly different characteristics. The second biggest one is Litecoin, which advertises that transactions are faster, and that the mining system is fairer than bitcoins. Theoretically, any one of these would suffice if you're a rich person in China looking to get your money outside the border.
But in practice, several of these wouldn't suffice. For you to get your money out of China you need to be able to buy coins in size, and then be confident that once you've switched them to a wallet outside of the country, that you'd be able to sell those coins in size for roughly the same price. It's highly unlikely you'd be able to find that kind of liquidity in any reasonable period of time. You'd be taking a gigantic risk that when you wanted to sell your Feathercoin, that there would be no buyers, and you'd be totally screwed.
You can probably obtain the coins and sell them without much disruption. So although theoretically the competing coins can technically do the job of getting past the border, you really need the network effects of a system with a high "market cap" to make it work.
So in a sense, the rising price makes it easier for the whole system to operate. Rather than being discouraging to the Bitcoin ecosystem, it enables it, because there's enough money in the system to absorb the needs of buyers and sellers doing transactions. Felix Salmon wrote a post titled Waiting for Bitcoin to get Boring in which he argued that Bitcoin bulls should be more excited by long periods with little volatility rather than the periods like recently where the price goes ballistic.
But while that seems intuitive if you think of Bitcoin like a "currency" that needs stability, it doesn't necessarily jibe with the thinking above. Higher and higher bitcoin prices enable transactions in size. Rather than the high price being a hindrance, the high price expands the market. There are all kinds of reasons to be compelled by anti-Bitcoin and to be deeply skeptical.
The Economist had a great piece Saturday about how there's a huge and growing technical strain on the whole Bitcoin network that could cause an implosion.
And the cult-like fanaticism of Bitcoin bulls spewing warmed-over goldbug cliches about the instability of fiat currency or the demise of the Fed should make anyone skeptical. In mining pool Ghash. The pool has voluntarily capped their hashing power at Bitcoin is pseudonymous , meaning that funds are not tied to real-world entities but rather bitcoin addresses. Owners of bitcoin addresses are not explicitly identified, but all transactions on the blockchain are public. In addition, transactions can be linked to individuals and companies through "idioms of use" e.
To heighten financial privacy, a new bitcoin address can be generated for each transaction. Wallets and similar software technically handle all bitcoins as equivalent, establishing the basic level of fungibility. Researchers have pointed out that the history of each bitcoin is registered and publicly available in the blockchain ledger, and that some users may refuse to accept bitcoins coming from controversial transactions, which would harm bitcoin's fungibility.
The blocks in the blockchain are limited to one megabyte in size, which has created problems for bitcoin transaction processing, such as increasing transaction fees and delayed processing of transactions that cannot be fit into a block.
Bitcoin is a digital asset designed by its inventor, Satoshi Nakamoto, to work as a currency. The question whether bitcoin is a currency or not is still disputed. According to research produced by Cambridge University , there were between 2. The number of users has grown significantly since , when there were , to 1. In , the number of merchants accepting bitcoin exceeded , Reasons for this fall include high transaction fees due to bitcoin's scalability issues, long transaction times and a rise in value making consumers unwilling to spend it.
Merchants accepting bitcoin ordinarily use the services of bitcoin payment service providers such as BitPay or Coinbase. When a customer pays in bitcoin, the payment service provider accepts the bitcoin on behalf of the merchant, converts it to the local currency, and sends the obtained amount to merchant's bank account, charging a fee for the service. Bitcoins can be bought on digital currency exchanges. According to Tony Gallippi , a co-founder of BitPay , "banks are scared to deal with bitcoin companies, even if they really want to".
In a report, Bank of America Merrill Lynch stated that "we believe bitcoin can become a major means of payment for e-commerce and may emerge as a serious competitor to traditional money-transfer providers.

Zero Hedge claimed that the same day Dimon made his statement, JP Morgan also purchased a large amount of bitcoins for its clients.
You can have cryptodollars in yen and stuff like that. Bitcoin has been labelled a speculative bubble by many including former Fed Chairman Alan Greenspan [] and economist John Quiggin.
Lee, in a piece for The Washington Post pointed out that the observed cycles of appreciation and depreciation don't correspond to the definition of speculative bubble. It's a mirage, basically. Two lead software developers of bitcoin, Gavin Andresen [] and Mike Hearn, [] have warned that bubbles may occur. Louis , stated, "Is bitcoin a bubble? Yes, if bubble is defined as a liquidity premium. Because of bitcoin's decentralized nature, nation-states cannot shut down the network or alter its technical rules.
While some countries have explicitly allowed its use and trade, others have banned or restricted it. Regulations and bans that apply to bitcoin probably extend to similar cryptocurrency systems. Bitcoin has been criticized for the amounts of electricity consumed by mining.
