Long life miner
some mine cards look good because there's no st in the mine machine, but because the hardware has been overused, all kinds of unstable problems may appear when you play games on the computer, And manufacturers generally do not guarantee the quality of mine cards.
The life of the graphics card is the same as that of the general electronic components, which is 6 to 10 years< br />
generally, the service life of mining machines is the whole network, and the relationship between computing power growth is the biggest, because the updating speed of mining machines is amazing. If you can't keep up with the cutting edge of the times, it's very difficult to make profits by using the old mining machines. Naturally, this kind of mining machine will be eliminated, short days, long months, but the general mining machines are rarely used for a year
of course, if the quality of the miner is OK, it will be OK to use it for one or two years
if your electricity price is low or free, then your mining machine will have a long service life, because a large amount of mining consumption is electricity
of course, it is only related to the price of currency. If the price of currency is high and profitable, the life of mining machinery will be delayed, and if the price of currency remains low, the mining machinery will be eliminated quickly.

A: first, block height does not refer to the capacity of the blockchain
Second, the connotation of block heightblock 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 block2. 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
Theblock 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
Theblock height is not a unique identifier
Mining graphics card life is basically 1 to 2 years. There is no accurate figure for the service life of the graphics card. It can only be said that the general mainstream graphics card can be used normally for about 3 to 5 years. However, e to various internal and external reasons, some graphics cards broke after one or two years of use, while others did not break after more than five years or even six or seven years of use
for a long time full load operation or mining graphics card, because the long-term full load operation, graphics card has been running at high temperature, will greatly shorten the life of the graphics card, basically one or two years will appear problems, physical fitness better graphics card, life is relatively long
{rrrrrrr}
2021 mining graphics card with the highest cost performance:
1, NVIDIA RTX 3060 Ti
NVIDIA rtx3060ti can be said to be the most cost-effective mining procts at present. It not only has the performance close to rtx3070, but also has lower function, so it is more cost-effective. It can be said that it is the first choice of 201 mining graphics card
NVIDIA RTX 3070 also has an excellent price. It can provide 60mh / s performance output under 130W power consumption, and has no other problems except the price slightly exceeds 3060 ti The NVIDIA RTX 3080 provides a performance output of about 100mh / s at 220W power consumption. The power consumption is slightly higher, but the output is also considerable4. Except for the above n card, there is finally an a card. At the level of 190W power consumption, it can output about 80MH / s performance output, which is also a very excellent proct
5, NVIDIA RTX 3090
finally, you must be familiar with this proct. NVIDIA RTX 3090 can provide about 120mh / s or more at a power level of 285w. Of course, Xiaobian does not recommend you to buy the graphics card. After all, there are too many mine owners and the price of the graphics card is rising step by step. The above procts may all be at a premium. You guys need to think about it
