How long does it take for the best graphics card to dig for bitc
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
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 />
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.
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.
1. Integer data (integer long)
both integer and long type values are integers. After users define a variable as an integer variable, they can only assign integers to the variable. Integers are faster than floating-point numbers and occupy less memory. Integer type values have a certain range, - 32768 ~ 32767, if beyond this range, we need to use long
2. Single double values
single and double values are floating-point values, which represent real numbers with decimals. Single precision can be accurate to seven bits, while double precision can be accurate to 15 bits. When users select these data types, they should pay attention to the value range of variables. And when the value is an integer, in order to speed up the operation, it is not necessary to define the variable as floating point. For large floating-point numbers, D, e format input and output can be used.
