Professional miner better upgrade or graphics card

1. mining now? Your 12 graphics card mining machine is basically impossible to make money, it's better to buy a fund to speculate in stocks

2. Graphics card uses GPU's general computing power for mining calculation, and its performance is much better than simple CPU calculation, because GPU has a large amount of concurrency
the professional mining machine does not use GPU, but a special mining chip, which is an ASIC. This kind of chip can only be used for mining, and has no other functions, but it is highly efficient in its own work and faster than GPU.

3. Mining machine can't be used as a computer, it can only be used for mining. Mining machine is certainly better than computer.
home computer can't even earn back the cost of digging bitcoin
at present, the home computers all dig up the Leyte coin, because there is no special Leyte coin miner, so it should be able to earn money
hope to adopt.

4.

Mining graphics card is faster than CPU, professional mining machine is faster than graphics card because: BTC task is a very simple decryption calculation, does not need too many instructions

That is to say, the task of BTC only needs some specific transistors

the CPU is used to carry out the mining task. Because the CPU needs many transistors to execute various instructions, many transistors are idle in a cycle

5. It seems that making money in the early stage is unsatisfactory, but making money in the later stage is quite fast. I recommend to practice double mining (mining and medicine) in the early stage, and then come to the auction house directly. In this way, before 60 years, it is still rich.

6. At present, the most valuable currencies for investment are rare ancient coins, which are unnecessary for a large amount of existence, and rare commemorative gold coins issued by the state. These should have the largest value-added space, waste a lot of money, and can be collected if there is more money.

7. blockchain is composed of blocks. A block contains about 400 transactions, which are packaged into a blockchain and then form a tamper proof blockchain
the packer of the transaction is the miner, and the income from the miner's packaged transaction is bitcoin
miner's income consists of two parts:
1. Service charge is required for package transaction (users pay part of bitcoin)
2. A reward (bitcoin) will be automatically generated for each block generated

8. Professional mining machine, now with the graphics card to dig are retail, large mines are using a chip to dig, computing power is dozens of times the graphics card.
