Sale of 1070 mining machines
It's about 37 yuan
let me first introce the reward mechanism of bitcoin system
bitcoin can basically dig out a block every 10 minutes through system settings. The reward for each block is given to the miners who dig out the block. The miner who digs out the block is called the block miner. The block miner will record the legal transactions in the bitcoin network to the blockchain, so that the miner can receive the service charge for bookkeeping
there are two parts in the reward for the block Miner: one part is the reward given by the system, which is called coinbase reward (also known as system issuance reward), the other part is the reward for bookkeeping, which is called miner's fee. The coinbase reward started with 50 bitcoins. For every integral multiple of 210000 blocks, the coinbase reward will be halved. This is what we often hear about bitcoin mining reward halved in four years
at the present stage, the reward of coinbase is 12.5 bitcoins. At the present stage, the average transaction miner fee received by miners for digging out a block is about 0.1 bitcoin (not fixed), that is to say, the average reward received by miners for digging out a block is about 12.6 bitcoin
about 99% of miners' rewards come from the system's coinbase rewards. According to the bitcoin system, one block can be g out every 10 minutes on average. The number of new blocks that can be g out in one day is 144 (60 * 24 / 10 = 144). At present, the number of bitcoins that can be g out every day is 1800btc (144 * 12.5btc = 1800btc). With the miner's fee of about 0.1btc per block, the total reward for all miners in one day is about 1814.4btc
Mining machinery may focus on different projects. Taking IPFs mining machine configuration as an example, the server level CPU such as amd Xiaolong 7302 is generally used; Most graphics cards are made of NVIDIA 2080ti, which can be proced in different factories; Seagate enterprise hard disk is the majority of hard disks, with large capacity, reliability and long-term operation of 7 * 24 hours
as a middle-aged miner for 13 years, let's talk about the feeling of mining before.
I bought four mining machines in the past. Bitcoin uses CPU and I'm not familiar with it, so I use the form of buying graphics card to dig Wright's coin.
the first one is a simple double card mining machine, not a mining machine strictly speaking, but a double 7950 machine, At that time, I thought about digging for a while. If I didn't make money, I could still play games by myself. As a result, I found that the efficiency was really not high. Later, I used to dig some dog money and play with it.
the second one was the popular 6-card miner in those years. At that time, there was a powerful motherboard, which could run for 6 yuan by connecting with the PCI adapter and changing the BIOS. At that time, I could dig a lot of Wright's money every day with this machine, It's a pity that there are too many people digging, so it took more than 80 days to dig the coins. The third and the fourth are professional mining machines. At that time, the new chips were used to mass proce mining machines. Although they were expensive, the power consumption decreased a lot. It took about a year to dig, In the end, he retired, g up other counterfeit coins for a while, and then sold them.
generally speaking, many websites have no credibility at all in the past few days. They actually know what the concept of excessive increase in computing power is after digging up the money.
when ZF suppressed it, the assets immediately shrank by nearly 70%, but they still didn't sell because of their faith, On the contrary, after selling the miner, I bought some coins and put them in my hand. When I bought 100, I g them and only bought 15. Hey, the miner was sealed and put under the bed. After waiting for three years, I found that it rose again. This year, when bitcoin rose to 2W, I sold some Leyte coins and paid the down payment. Almost 300 of them were sold. Now it seems that the highest is 380, Ha ha
now I still have some money in my hand, and I plan to hold it for a long time, but I won't dig any more. However, I still have a lot of orders with our first-class suppliers. In the past two months, I sold nearly 150 cards, and the more I sold, the more I sold. Some cards are about to double, which is even crazier than that in 2013, The existence of e-money has its own value in the end, but it does not deny that there are so many speculators who come in to fight. There are indeed those who pursue the price. After the boom, there will be a wave of leeks cutting. In the final analysis, bitcoin is just an investment. Everyone feels different about the risk. The strength of big funds is still strong, and it is inevitable for retail investors to be cut, But it's better than A-share at least.
mining is not a good thing. The big miners are in the remote areas with low electricity charges, many mining machines and low cost. Most people dig at home, and that's just a little fuss.
finally, it's not a good thing to grow too fast. Those who are confident can come in and show their operation. If they don't have much ability, don't come in, Only by routine
it's up to the family to dig. Large can be prepared on a host of 6 or 8 graphics cards, need rx570 (580), or gtx10610170. Then in the preparation of 20 hosts or more can make money. At least 10
to give you an example, if you need to use neural network to judge whether the land on the satellite photo is desert or not, the training sample is to select some points from the remote sensing photo, and then manually interpret or field survey to get the training sample.
ICO is usually launched before the completion of the project. The funds raised are used for the development work of the founding team to help the project release smoothly. For some large projects, some of the funds obtained in ICO will be taken over by the foundation to support the continuous development of the project. ICO represents the initial allocation mode of cryptocurrency token, which is common in POS consensus algorithm
ICO participants contribute to the success of the project. They can help promote, build larger communities, and get more people to know about the new project. At the same time, they can provide early liquidity for tokens. Of course, ICO participants are driven by potential benefits. They expect the token price to be higher than that ring the ICO period after the project is released.
but the efficiency of single card is not enough. You have to get 6 cards of mining machine to calculate at the same time to dig back the electricity charge.
at that time, the a card was emptied, and the N card was not efficient, but it was also played by miners who could not buy it. In particular, the card you mentioned is a beggar's card, and it is out of stock
after 17 years, GPU mining was replaced by professional mining machine, and a large number of refurbished cards appeared in the market
therefore, there must be a lot of renovated mine cards on Taobao. Especially when gtx1070ti is on sale, gtx1070 is almost out of proction.
