according to the 2017 Credit Suisse report, the number of millionaires in the world is about 36 million. Therefore, if a "bitcoin club" composed of users with more than one bitcoin is established, the number of members of the club will not exceed 21 million, less than the number of global millionaires
bitcoin is graally released through the so-called "mining", and today it has issued more than 85% of the total. It's going to get slower and slower, and it's going to stop completely by about 2140. At present, bitcoin's annualized inflation rate (3.7%) is far lower than that of the US dollar since 2008 (36%), and it will further drop to 1.7% after half a day's rection next year
theoretically, one bitcoin can be infinitely subdivided by expanding the precision of digital storage or by upper layer expansion (such as lightning network technology). However, the transfer fee actually limits the value of bitcoin, which is too small. Therefore, the current code only supports subdivision to one in 100 million. The unit calls it "cong", which is named by netizens in memory of the inventor of bitcoin, Nakamoto. Don't say that one bitcoin is too expensive, because you can buy 0.1 or 0.01
bitcoin is in the address. Address is a number, but for the convenience of writing and using, it is encoded into a string form.

For example, BTC can be exchanged for LTC, or LTC can be exchanged back for BTC; Exchange eth for BTC, or exchange BTC for eth again. The transaction object of the currency to currency transaction is the "transaction pair" mentioned in the previous article. The price of the currency to currency transaction is the price of the transaction pair
the advantage of currency trading is to bypass the off-site legal currency trading, and directly complete the transactions between different currencies on the field, so as to avoid the miner's fee and time for withdrawing currency.

During the promotion period, some new reliable platforms generally have the activities of recing or exempting handling charges and distributing candy.
