Current cost of BTC

1. There are three main reasons why bitcoin is valuable:
first, bitcoin is not proced out of thin air, but it costs a huge cost of mining output. At present, the mining cost of each bitcoin has reached tens of thousands of dollars, while in 2010, the cost of mining a bitcoin was less than $1. Diamonds are g out by machine and bitcoin is g out by computer. There is no difference between them in essence. The difficulty of mining diamonds comes from the outside world, and the difficulty of mining bitcoin comes from computer programs. The greater the difficulty, the higher the cost. Diamonds are physical objects that can be seen, while bitcoin network is an accounting system
Second, bitcoin is more scarce than diamonds. Diamonds are expensive because they are scarce. If diamonds are as common as gold and silver, they will not be able to support the high price. Bitcoin is also scarce, with a total of 21 million bitcoins. Although diamonds are rare, new mines appear from time to time, so the total amount is unknown. From this perspective, bitcoin is more scarce than diamonds. At first, people didn't realize the value of bitcoin. A programmer once spent 10000 bitcoins to buy two pizzas. At present, the programmer seems to have missed several hundred million< Third, the issue of bitcoin is the result of a consensus. By understanding the mining principle of bitcoin, we can know that the issuing process of bitcoin is a process of bookkeeping. It is the proct of miners' labor, not out of thin air. Bitcoin relies on computing power, and credit comes from the consensus of all miners. Because each block needs to broadcast the whole network before it is connected to the chain, and it can be connected to the chain only after the consent of other miners. In other words, the issuance of each bitcoin is actually approved by all miners in the whole network, which is a consensus mechanism formed among miners
in conclusion, from the perspective of commodities, the value support of bitcoin comes from the mining cost; From the perspective of currency, the value support of bitcoin comes from consensus.

2. It's hard to say. Anyway, lightcoin mining is basically no longer profitable, so is bitcoin. Some time ago, e to the sharp drop in the price of lightcoin, Zeus lightcoin cloud mining project has stopped mining. The mining of Laite coin is still so, and the mining of indivial investors is even more difficult. There are different opinions about the cost of bitcoin mining, some say 1500, some say 500. This has something to do with the performance and electricity price of the mining machine.

3. The concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system
unlike all currencies, bitcoin does not rely on a specific currency institution to issue. It is generated by a large number of calculations based on a specific algorithm. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity

according to the notice on preventing the financing risk of token issuance, there is no approved digital currency trading platform in China. According to China's digital currency regulatory framework, investors have the freedom to participate in digital currency transactions at their own risk

4. At present, the most popular way of bitcoin trading is contract trading. According to the rise and fall of the price, it is far better to obtain income than the traditional mining and direct trading. After all, there is no need to really hold virtual currency, just need to judge whether the price is up or down, which is very suitable for the existing investors, simple and convenient

5. This is hard to say. Ant miner once said that its mining cost is only about 200 yuan. In September 2014, major mining machinery manufacturers generally believed that their mining cost was around 2000. To be specific, the following figure is the basic information of bitcoin mining Revenue:

6. Mining now? The cost of bitcoin is too high! Now that the situation is over, you might as well know about the Khan currency, which is a real virtual digital cryptocurrency. Now the price is only a few cents, which is very cost-effective. You can know about it

7. Bitcoin mining machine can be done for tens of thousands of yuan now, but the high electricity cost is not affordable by most of us. It is not recommended that bitcoin can choose some other currencies for mining.

8. Twenty one hours ago, JPMorgan analysts said that in the fourth quarter of last year, the cost of procing a bitcoin was about $4060 worldwide. Given the current transaction price of bitcoin itself, JPMorgan believes that the current value of bitcoin is lower than the cost of mining. However, the cost of Chinese miners is relatively low, with an estimated cost of about $2400 per bitcoin. Analysts said that more high-cost procers are expected to be forced out e to negative profit margins, but JPMorgan further said that this has not yet happened and that the proction shares of mining companies in the Czech Republic, the United States and Iceland have actually increased slightly in the past year or so. But if low-cost Chinese miners continue to exist, the marginal cost per bitcoin could fall to less than $1260< According to Jake chervinsky, a U.S. government law enforcement defense and securities litigation lawyer, bitcoin ETF is still likely to be approved before the end of the year, but it will depend on: 1. When the ETF proposal will be submitted; 2. The situation of bitcoin market when sec makes decision. Once a proposal is submitted, the SEC has 240 days to approve or reject it. Therefore, any proposal submitted before May 5 of this year needs to be finalized by December 31. He concluded: ten months after the development of cryptocurrency ecosystem, it is entirely possible for bitcoin ETF to be finally approved

in terms of technical graphics, bitcoin has not changed much this week, so our previous analysis view remains unchanged, and we continue to wait for the market to appear, supporting US $3550 and resisting US $3700. At present, even if bitcoin breaks through or falls below the pressure and support we mentioned, there is no short-term operation opportunity. The easiest way for us to judge whether the trend changes upward is to focus on the daily level of 20ema. 20ema is an important reference for the market turn. Only by standing on and stabilizing 20ema, can we carry out future operation for BTC.

9. BTC is bitcoin, bitcoin, abbreviated as BTC, is an electronic currency proced by open-source P2P software. It is a network virtual currency with high security, high encryption and decentralization. It is not supervised by a single department or indivial, but by all the people who hold bitcoin
bitcoin features: no freezing, no tracking, no tax, and extremely low transaction cost. Compared with people who speculate in currency, it is wealth, and people outside the currency circle may think it is a fraud
at present, the mainstream digital currencies include bitcoin, Ethereum, bitcash, EOS, Ruibo, etc., which can be properly invested, and the transactions are risky, so we should invest cautiously.
