A day's profit of braised pork mining
Only those whose electricity charges are controlled within 0.3 yuan can mine. At present, the daily income of a bitcoin S9 is about 55 yuan (calculated at 7000 yuan), so 30 is 30 × 55 = about 1650 yuan (210000 yuan)
bitcoin is a kind of universal encrypted electronic currency in the world, and it is completely autonomous by users. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
the concept of bitcoin was first proposed by Nakamoto in 2009. Unlike most currencies, bitcoin does not rely on specific currency institutions to issue. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of money circulation. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million
bitcoin can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual goods, and they can also use bitcoin to buy real-life goods. On December 11, 2017, bitcoin futures began trading on the Chicago Board of Options Exchange (CBOE). On January 24, 2018, the Bank of Indonesia announced the ban on bitcoin payment
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
I don't know what it is. There are risks in starting a business, so investment should be cautious...
Yes , on August 21, Beijing time, recently, TSMC officially announced that the 7Nm chips, which were put into large-scale proction in 2018, have now proced more than 1 billion 7Nm chips. At the same time, more than 100 procts began to use the 7Nm chips proced by TSMC
it is understood that TSMC's first 7Nm chip started large-scale proction in April 2018. Meanwhile, the billionth 7Nm chip was proced in July this year. In these 27 months, TSMC has to proce more than 37 million 7Nm chips every month
according to the data, the first batch of TSMC 7Nm procts include bitmainland's miner chips, Xilinx's FPGA chips, apple A12, Huawei's Kirin 980, etc
