1. 
at present, the computing power of bitcoin in the whole network has reached 2.36 billion hash collisions per second, which is equivalent to the number of water droplets in more than 200000 50 meter long standard swimming pools. But even with such a large amount of computing power, it will take about 10 minutes to hit a hash value that meets the requirements
in 2012, bitcoin's output was halved for the first time, and in July 2016, bitcoin's output was halved for the second time. At present, 12.5 bitcoins are awarded for recording one page of account book. The next halving will take place around 2020, and the total number of bitcoins will not increase by 2040, with a total of 21 million. In other words, the difficulty of digging bitcoin is increasing, while the time required is increasing
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. Now the hottest miner is not bitcoin miner, but filecoin miner. The year can be hot. It's said that the miner will be on the main chain in the middle of the year. Now it's delayed. Now it's said that the miner will be on the main chain in the middle of next year. Many people have bought the miner for a long time, but they are digging other coins, and they can't dig filecoin yet
the cost of mining machinery is neither expensive nor cheap. It takes time to recover capital and make profits. This year's currency market is in downturn, and the cost of digging bitcoin is increasing, but the price has been between us $6000-7000, so there is no profit to cover
now mining can only be excavated before the market goes up to sell for money. The average time for the mine to go back is more than 6 months. Next year, whether the market is good or not is still unknown. Moreover, the heat of the digital money has dropped, and the bubble is still very large. p>
4. 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:
5. Now there is no way to dig bitcoin, you can try to dig RCO, ordinary desktop and notebook can dig mine. Go to their official website to download a wallet and run it directly on your computer. Please call me Lei Feng.
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. First of all, it depends on the background of the company. Then it depends on the company. Where is the server and what is the mode? Violation of the law or not, if there is no problem with these, you can invest!
9. From the traditional promotion is divided into offline way, mainly about the promotion in the entity and the Internet is divided into different ways. The main promotion of
blockchain is in e-commerce network promotion channels (database marketing, social media marketing, online advertising, mobile client, distribution platform, search engine marketing, resource cooperation marketing, classified information, etc.). The mode is always changeable, but it's always the same, no matter which promotion channels are only for a common goal: profit
the above is purely personal.
10. It's mainly about the cost of mining machines and electricity. Now a second-hand new-type bitcoin mining machine costs tens of thousands, and there are thousands of older ones, but the performance is poor. If bitcoin doesn't plummet, it's OK to return half a year. For example, the energy carrying platform, I feel that the service is the best, mining machines and mines are provided in one-stop, and the revenue is the most stable, Mining machines and mines have also been audited and verified, and the information is transparent and open, at least they will not be mined.
