1.
21.5 * 3600 seconds * 24 hours = 1857600 M / day
1857600 / 1024 / 1024 = 1.7715 T / day
a t of computing power / day can dig bitcoin worth 4.03 yuan
1.7715 * 4.03 = 7.14 yuan / day
since 2017, bitcoin has reached new heights. Yesterday (May 23), the value of bitcoin broke through the ￥ 16000 mark, hyping virtual currency, becoming a matter that the general public can participate in, And a little bit of technical level, both fried money, but also began to have the technical content of mining
as we all know, virtual currency has a numerical peak, the more difficult it is to dig. In fact, it's hard to judge whether to lose money or not if we continue to dig. Therefore, in the end how to dig, dig what can be the fastest back to this, this paper studies the above two core issues based on the current market situation
2. This is n card, not suitable for mining
the architecture of a card is different from that of N card. AMD is a brute force heap stream processor without considering the operation efficiency, while NVIDIA greatly improves the operation efficiency, but the number of stream processors is small. The final result is that both sides have their own advantages, and they are almost tied in all kinds of 3D games. In general computing applications, n-card has the upper hand, but the leading advantage of n-card may not be the problem of efficiency, but the software optimization and program development are in place
bitcoin digger adopts SHA-256 algorithm, which can perform a large number of 32-bit integer cyclic right shift operations. This operation can be implemented by a single hardware instruction in AMD GPU, while it needs three hardware instructions to simulate (2 Shift + 1 add) in NVIDIA GPU, This one alone brings amd an additional 1.7x computing efficiency advantage (about 1900 instructions to perform SHA-256 compression operation, rather than about 3250 instructions from NVIDIA)
in this way, AMD's high floating-point computing power and algorithm efficiency advantages make the performance of AMD GPU in password cracking and bitcoin mining more than three times that of NVIDIA GPU!

3. This is legal in some countries, and the domestic attitude is not very clear. Anyway, it is not illegal
4. Bitcoin is a distributed virtual currency without a central bank. The real value of this kind of currency depends on people's degree of speculation. If there are more speculators, it is very valuable. If there are fewer speculators, it can be said that it is penniless
brother, have you fried the futures trading category, how is it going? If you haven't even fired the futures, it's best not to mention it. To tell the truth, this is a virtual bubble. It's hot now, but once it is gone, it will be penniless.

5. A distributed ledger technology of blockchain! The jester of ether doesn't know what it is, so we should be cautious
6. Pure graphics card miner, now dig BTC, LTC, NMC, etc., which kind of currency is more profitable? Have the actual operation of the predecessors, give more advice!!!!!!!!!!!
7. Generally speaking, AMD's graphics card is more suitable for the most mining graphics card e to the factors of architecture, price and so on
hd7990 is the current king. It is said that the electricity charge for mining each bitcoin is 130-140 yuan. In other words, a monster card like hd7990 needs to work for about 20 days to get a bitcoin. A bitcoin may consume 300 watts of power, not counting the loss of computers
in addition to the graphics card, other hardware of the mining platform will also consume electricity. CPU / motherboard, memory, hard disk, including the power supply for the whole machine, will still need electricity because there is no 100% conversion rate. Compared with the display that can be turned off in pure standby, they have to intervene
the faster the graphics card mining speed is, the less unnecessary power consumption will be consumed for each bitcoin acquisition. In this case, the graphics card with fast computing speed often has more advantages. If a multi card platform is established, the net profit per unit time will be higher
the lower the performance of the card, the more power it consumes on average
in a word! Investment must be cautious.

8. There is an upper limit for bitcoin, which is controlled by a few people. Now there are too many people to dig, making it more difficult to dig. Digging for half a year may not be able to get back to the original. In the end, I worked for foreigners for nothing.
9. The principle of digging bitcoin is to calculate the decryption result according to a certain mathematical formula, which corresponds to a certain amount of bitcoin. The video card's stream processor is large in scale, which is more efficient than CPU in computing virtual token. For example, rx480 has more than 2000 stream processors forming a GPU core. This structure is suitable for mining. The relative CPU is generally 2-core to 6-core, which is suitable for complex operations. CPU is equivalent to contractor, GPU is equivalent to worker, and mining depends on worker.
