Bitcoin 100 times contract revenue
For bitcoin, a unique virtual currency, its intrinsic value is very uncertain, and it has great risks and fluctuations. For most ordinary investors, it is not recommended to speculate in this kind of currency{ RRRRR}
and now with the entry of large-scale mining workers, the number of bitcoin mining is also rising, and the number of new bitcoins that can be g out is also decreasing. Therefore, for this future development trend, we must find a new way to rece our bitcoin, if no one believes in this market any more, Then it is very likely that we will not find a new successor to carry out the corresponding supervision. So for these investors, the money they have will become worthless, so for most ordinary people, investing in bitcoin is very risky
bitcoin futures contracts, for example, at $10000, use $500 to open 100 times leverage, which will rise to $10500, which means an increase of 5%. 100 times leverage means 5 times profit and $2500.
in addition, CPU is not good at parallel computing at all. It can perform more than ten tasks at most at one time. This is far from the fact that the graphics card has thousands of stream processors. The graphics card is too high, so we slowly develop the corresponding mining algorithm for the graphics card
taking BTC as an example, its basic algorithm principle is to take all transactions within 10 minutes as an input and add a random number. When all transactions within 10 minutes are added with your random number, a hash of sha256 is calculated. It's almost full of integer operations. It's just like a special design for a graphics card. The graphics card is very suitable for this kind of brainless algorithm. The more the number of stream processors, the better
as far as hash computing is concerned, it is almost all independent and concurrent integer computing, and GPU is designed and proced for this. Compared with the pitiful 2-8 threads of CPU and the astonishing length of control judgment and scheling branches, GPU can easily perform integer calculation concurrency of hundreds of threads (brainless brute force cracking without any judgment is the strength of a card)
OpenCL can make use of a large number of unified shaders on GPU chip, which can be used as resources for integer calculation. The resource of stream processor of a card is several times that of N card (the same level card)
but later, we found that the graphics card is still too weak, and the computing power can be greatly improved by directly using the ALU unit of large-scale ASIC stack. The computing power of the palm sized computing board is dozens of times that of the graphics card, so now bitcoin can't dig without a special ASIC miner
although a large number of interdependent and random memory access instructions are introced into the script algorithm used in the later LTC, when the footprint is large enough, a large number of cache failures will occur at the L2 level or even TLB level of GPU, resulting in more DRAM accesses, so as to weaken the advantage of ASIC / FPGA in integer operation performance compared with GPU, However, it is still targeted to develop mining machines. At present, only specialized mining machines can dig
however, the second generation of virtual currency (such as Eth and Zec) has absorbed the experience of the predecessors' blasted algorithms, and made more special optimization on the mining algorithm to prevent the occurrence of brainless operations. It has high requirements for video memory, so it can effectively resist the invasion of mining machines
because eth can only rely on graphics cards for mining, the rising price and shortage of graphics cards started in the second half of 2017. Many mine owners sold thousands of graphics cards to set up mining machines to mine these virtual currencies
over time, we all think that CPU can't mine, but in fact, the efficiency and benefit are too low.
As of press release, bitcoin has risen to above US $44000 in the short term, a record high. It's still floating
but if you drop 5 points, your principal will not burst.
