1. The revenue from the purchasing power contract varies from two to three years. You need to book and purchase the
mining machinery in advance, search for electricity or look for the mine trusteeship, which has a lot of deployment costs and electricity costs. It also needs manual maintenance. The mining machinery has a service life. In addition, the mining machinery market is updated rapidly, so the cost of such calculation is very high, and it is also very troublesome.
2. The most advanced bitcoin mining machine, one to two years to dig out a bitcoin, bitcoin mining is now too difficult. If you want to dig, you can dig ether currency. Now it is steadily appreciating every day. According to the current development trend, it will be able to recover its capital in about seven months, and then it will be profitable< br />
3. If you want to make profits online, you still have to look at the risk of fire. If you are optimistic about the risk, you can do it again. Don't take the risk to do it.
4. It's a kind of
digital currency. I've invested in mining machinery in NB cloud mine for some time, and the income is good.
5. Bitcoin is a winner take all, and you can only get profits if your
computing power reaches a certain level. Therefore, it is suggested that ordinary retail investors should find a reliable exchange, such as okex exchange, to purchase directly.
6. You buy a bitcoin miner! B network's graphics card machine is not working now. It takes five or six months to buy a chip machine, and the 12t-14t can proce 0.002-0.0025 bitcoins a day. Bitcoin is now up to the top [wdy520s]. Hope to adopt it
7. A: first, block height does not refer to the capacity of the blockchain

block height is the number of blocks linked to the main chain, that is, the number of blocks connected to the blockchain
Block height is the indicator of block
2. The block has two identifiers, one is the hash value of the block head, the other is the block height
3. The hash value of the block head is the number obtained by the second hash calculation of the block head by sha256 algorithm
The
block hash value can uniquely and explicitly identify a block, and any node can independently obtain the block hash value by simply hashing the block head
4. Block height refers to the position of the block in the blockchain
The
block height is not a unique identifier

8. The cooperation mode of exchange + mining pool + mining machinery will give full play to the advantages of instrial chain and highlight the polymerization effect. At present, HRT has issued 400 million pieces, 45% of which are used for access to computing power, 5% for airdrop to Cen holders, 15% for team incentive, and the rest for long-term operation and development of computing power ecology.
9. It is suggested to buy computing power in the computing power platform for indivial mining, so that the investment cost is low and the investment risk is small. The enterprise investment suggests to buy Mining machinery directly. The computing power and mining machinery guarantee of star ant are good, and indivials and enterprises can make a reference choice for mining.
