1. Machine: two ant double blade mining machines (rated speed: 180gh / s, rated power consumption: about 360W)
2. Network: ordinary family 8m broadband connection
3. Test time: from 11:00 p.m. on January 27 to 7:00 a.m. on January 28, 2014, a total of 8 hours
4 Comparison:
a miner in btcguild (EU stratum. Btcguild com:3333
the average speed of 8 hours is 175.92gh/s, and the profit is 0.01424974
one miner operates in f2pool (stratum)+ tcp://stratum.f2pool.com : 3333)
8 hours average speed 180gh / s, revenue 0.01230566
5 The test results are expected (the theoretical value under the difficulty of the day does not consider other factors):
the profit of an ant double blade miner in btcguild mine is 0.00194408 more than that in f2pool mine in 8 hours, 0.00024301 more per hour, 0.00583224 more in 1 day (24 hours), and 0.1749672 more in each month (30 days)
PPLNs: (the purest Group Mining) full name is pay per last n shares, which means "pay income according to the past n shares", which means that once all miners find a block, You will allocate the currency in the block according to the proportion of each person's own shares Share means share)
in PPLNs mode, luck is very important. If the mine pool can find many blocks in a day, then everyone's dividend will be very large. If the mine pool can't find any blocks in a day, then everyone will have no income
PPS: pay per share mode --- this mode is to pay for each share immediately. The expenditure comes from the existing bitcoin funds in the mine pool, so it can be withdrawn immediately without waiting for the block generation or confirmation. In this way, the operation behind the scenes of the pool operators can be avoided. This method reces the risk of miners, but transfers the risk to the pool operator. Operators can charge fees to make up for the possible losses caused by these risks
in order to solve the problem that PPLNs sometimes has a high profit and sometimes has no profit, PPS adopts a new algorithm. PPS estimates the daily available mineral resources of the mine pool according to the proportion of your computing power in the mine pool, and gives you basically fixed income every day
do you feel that this is a stable job? In fact, in order to avoid the risk of loss, the PPS model often charges a high handling charge of 7% - 8%< DGM: Double geometric method. It combines PPLNs and geometric reward type, so that the pool operator can avoid part of the risk. The pool operator will collect part of the excavated currency in a short time, and then return it to the miners with normalized value, such as charge and discharge of electric capacity. If you are lucky, you will get less money for each block and more money for poor luck
175btc: the mining node of 175btc works on a shares chain similar to bitcoin blockchain. Because there is no center, it will not be attacked by DOS. Unlike other existing mine pool technologies, each node's working block includes bitcoin paid to the owner of shares in the early stage and the node's own bitcoin. 99% of the reward (50btc + transaction cost) will be distributed equally to miners, and the other 0.5% will be awarded to those who generate blocks
bitcoin home has a detailed introction.
open source digital currencies such as bitcoin, lightcoin and dogcoin are truly confidential currencies. The token generated by crowdfunding projects on the European crowdfunding platform can only be regarded as a kind of asset certificate, just in the form of digital currency.
bitcoin prices are expected to continue to rise in the near future
when bitcoin broke the peak of 2019 in October 2020, it triggered the fastest and longest growth of currency destruction day (CDD). The index on the CDD chain indicates the & quot; Weight & quot;. It is calculated by multiplying the number of currencies in the transaction by the number of days after they were last consumed. This means that the higher the CDD, the greater the volume
However, since the beginning of this year, the selling of long-term sellers has not only slowed down significantly, but also almost returned to the level that triggered the selling in 2020. This shows that long term speculators are more and more confident that the price of bitcoin will rise in the short termas the source of income of bitcoin miners is the newly mined BTC, they often have to sell the mined BTC to pay for the electricity and other operating expenses. However, some miners tend to hype prices. By limiting the sale of bitcoin, they have become net revenue accumulators. This is expressed as a measure of the change in the net position of the miner, which shows a 30 day change in the supply held in the miner's address
the last time miners hesitated about selling bitcoin was nearly three months ago, before prices rose sharply. This positive change shows that miners expect prices to rise in the near future

because you said that you have plans to upgrade in the future, specially selected a 945 motherboard for you, after this motherboard you can upgrade absolutely, because Your requirements are not high, so I chose a CPU with enough memory for you.
the memory is only 256M. If you don't play games, it's enough. A hard disk is in place. If you choose 8m serial port, you don't need to move after upgrading. The chassis doesn't choose DVD recorder. The display is LCD, but I suggest that the memory should be changed to 512M.
that's all
