The available amount of BTC is insufficient

1.

The earliest is a kind of network virtual currency. It is characterized by decentralization, anonymity, and can only be used in the digital world. It does not belong to any country or financial institution, and is not subject to geographical restrictions. It can be exchanged anywhere in the world. Therefore, it is used as a money laundering tool by some criminals. In 2013, the U.S. government recognized the legal status of bitcoin, making the price of bitcoin soar

< H2 > extended information:

bitcoin is e-cash similar to e-mail. Both parties need "bitcoin wallet" similar to e-mail and "bitcoin address" similar to e-mail address. Just like sending and receiving e-mail, the remitter pays bitcoin directly to the other party through a computer or smart phone according to the recipient's address

starting from the essence of bitcoin, the essence of bitcoin is actually a special solution generated by a bunch of complex algorithms. A special solution is one of the infinite (in fact, bitcoin is finite) solutions that can be obtained from the equations. Every particular solution can solve the equation and is unique

many websites for technology players have begun to accept bitcoin transactions. Websites such as mtgox and btcchina, as well as some Taobao stores, can even accept services such as bitcoin exchange for us dollars and euro. There is no doubt that bitcoin has become a real currency in circulation, rather than a virtual currency like Tencent Q coin

Bitcoin network generates a new block every ten minutes. Every time a miner completes a block, he can get a certain amount of bitcoin as a block reward, and the reward will be halved for every 210000 blocks mined. Because the time for mining each block is limited to 10 minutes, at this rate, the period for the reward to be halved is four years, that is to say, the reward for bitcoin blocks is halved every four years

when the bitcoin block reward was halved for the first time, its price rose 25 times from 300 yuan to 7995 yuan; In the second half, the price rose 28 times from 5011 yuan to 140000 yuan. So many people predict that the third halving of bitcoin in May 2020 will lead to a sharp rise in the price of bitcoin, at least 10 times. However, these figures are not so clear. After halving in 2012, bitcoin prices rose for two months, and in 2016, there was almost no immediate response to deflation for a month. This may also be the result of the strategy of "buying rumors and selling news" implemented by some speculators

extended data:

after bitcoin halved, the supply slowed down, and keeping deflation through algorithm has always been a part of bitcoin protocol design. It was set up to ensure the value of bitcoin. By recing block incentives and setting the maximum possible supply of bitcoin at 21 million bitcoins, bitcoin has an anti inflation feature, which runs counter to the tendency of central banks to print money at will. At present, there are about 17.5 million bitcoins in circulation, and less than 3.5 million bitcoins are available for mining. When the next block award halves, bitcoin's annual inflation rate will drop from the current 3.8% to about 1.8%

maintaining deflation through algorithms has always been a part of the design of bitcoin protocol. It was created to guarantee the value of bitcoin. By recing block incentives and keeping the total amount of bitcoin at 21 million bitcoins, bitcoin is endowed with an anti inflation nature, which is different from the tendency of central banks to print money at will. At present, there are about 17.5 million bitcoins in circulation and less than 3.5 million available for mining. The next block award cut in half could rece bitcoin's annual inflation rate from the current 3.8% to about 1.8%. This will be the first time in bitcoin's history that it has fallen below the historical average of about 2% - 3% growth in gold supply

4. M. 2. The SSD of the PCI channel needs to occupy the PCI channel, and the tb250-btc of the six cards also occupies multiple PCI channels. In this way, once the PCI SSD is inserted, the lack of the PCI channel of the CPU will cause hardware conflicts, which will lead to the failure of some graphics cards. Moreover, the mining machine does not have high requirements on the hard disk. Therefore, the mining machine had better not use the m.2 SSD of the PCI

The price and quantity of purchase can be set in the price limit. Only the amount of RMB purchased can be entered in the market price column. The minimum bitcoin purchase of fire coin is 0.00000 1

according to the market price (71193.96usdt / BTC), it is 0.01018511 usdt. Once the balance of your usdt account is less than this number, it shows that the available quantity is insufficient

extended data

fire coin said it would stop virtual currency trading on October 31, 2017. In the future, the main layout of fire coin network is overseas transactions. As of the end of 2016, the accumulated turnover of fire currency reached 200 billion yuan

fire coin is a bitcoin trading platform, which has won a round of 10 million RMB capital investment from Zhenge fund, Dai Zhikang, Sequoia Capital (shareholders of many global well-known companies such as apple and Alibaba). Fire coin implements strict risk control management and operates stably

According to the announcement, the registration and RMB recharge business will be suspended from now on, and all users will be informed before September 30 that they will stop trading. At the same time, all transactions of digital assets against RMB will be graally stopped before October 31

this is displayed in the usdt trading area, which means that you don't have enough usdt to buy bitcoin. BTC / usdt means buying BTC with usdt, so your usdt stock depends on how much BTC you can buy< br />

6. After decting the service charge, your bitcoin exceeds the total amount you can withdraw. You can rece the amount you sell.

7. Can you describe the problem more clearly? Generally, electronic wallet transfer will not result in the failure to withdraw money.

8.

With enough power supply, there will be no shortage of power supply. All graphics cards used in mining need external power supply

eight graphics cards may not fit, but six are OK
