Ethereum mining is a scam
bitcoin uses SHA-256 encryption algorithm. When mining, it competes with computing power. In order to improve computing power, bitcoin has gone through four stages: CPU mining, GPU mining, FPGA mining and now ASIC mining machine mining, and the degree of specialization is getting higher and higher
Ethereum uses the ethash encryption algorithm. In the process of mining, it needs to read the memory and store the DAG file. Because the bandwidth of each read memory is limited, and the existing computer technology is difficult to have a qualitative breakthrough in this problem, so no matter how to improve the computing efficiency of the computer, the memory read efficiency will not be greatly improved. Therefore, in a sense, Ethereum's ethash encryption algorithm is ASIC resistant.
different encryption algorithms lead to great differences in mining equipment and computing power between bitcoin and Ethereum
at present, bitcoin mining equipment is mainly ASIC mining machine with a very high degree of specialization. The maximum computing power of a single mining machine is 110t / s, and the scale of computing power of the whole network is more than 120eh / s
the main mining equipment of Ethereum is video card miner, and there are very few specialized ASIC miner. On the one hand, the "ASIC resistance" of Ethereum mining algorithm improves the threshold of developing ASIC miner. On the other hand, after Ethereum is upgraded to 2.0, the consensus mechanism will be transformed into POS, and the miner can not continue mining
compared with the ASIC miner, the graphics card miner has two orders of magnitude difference in computing power. At present, the computing power of mainstream graphics card miner (8 cards) is about 420mh / s, and that of Ethereum is about 230th / s.
from the time dimension of the past two years, bitcoin's computing power of the whole network is growing rapidly, while Ethereum's computing power of the whole network is growing relatively slowly
The ASIC mining machine of 
bitcoin is monopolized by several major mining machine manufacturers, and miners can only buy it from the market; Although the graphics card miner of Ethereum is also manufactured by a special miner, the miner can buy accessories from the market and assemble them according to his own demand
because those who come in after mobile phone mining will be cut leeks
precautions:
1. In the past two years, various myths about blockchain "overnight wealth" have been constantly staged, and "mining" cryptocurrency has become a new trend of wealth, and mobile phone mining is becoming more and more popular
2. There will be special mining machines for real mining. After all, every mining machine is not cheap now. Mobile phone automatic mining can be obtained at a very low price. What you dig is not bitcoin. Basically, the counterfeit coin you send is not worth money. At that time, you will still be cut leeks
mining machine is a fraud
in recent years, bitcoin has become a new favorite for investment, and the price of bitcoin mining machine has also gone up by leaps and bounds. In 2019, Chongqing Xiushan County Procuratorate approved the arrest of a Wei, who defrauded by selling bitcoin mining machines
bitcoin is a P2P form of digital virtual currency, which can be converted into the currency of most countries. In theory, anyone with a computer can participate in bitcoin mining
because an ordinary miner on the market needs at least 30000 yuan, and a more advanced miner with less power consumption and higher mining speed needs 600000 yuan, it is very easy for buyers with the mentality of picking up a bargain to be cheated
Bithumb, South Korea's digital asset trading platform, has been hacked recently, and its damaged assets have rapidly reached billions of won, according to local media Jingxiang news. This report also led to a slight drop in the price of bitcoin, which reverberated from more than 18000 yuan to around 17800 yuan at this time
As an instry veteran level digital asset trading platform, okcoin has been committed to providing users with safe, stable and reliable trading services since its establishment in 2013. At the same time, okcoin bank has the most professional development technology team, financial proct team and technical security experts in the instry. It adopts the al storage mode of hot wallet and cold wallet online to ensure the safety of your assetsthe so-called "hot wallet" refers to the online wallet that can be connected to the Internet and is mainly used for daily affairs and activities. So what is cold storage
Science Popularization time: what is cold storage
cold storage of bitcoin wallet is a way to save the wallet offline. Specifically, players generate bitcoin addresses and private keys on an offline computer and store them properly. Later, bitcoin obtained from mining or trading platform can be sent to the offline generated bitcoin address. The private key generated by this computer will never appear on other computers or networks
so no one can steal your information! Unless you show it to others ~
for example, a big bitcoin user wants to ensure the absolute security of his bitcoin wallet. Even if the computer is hacked, the hacker still can't get the private key of bitcoin. In this way, the big user has to use cold storage technology. He generates several pairs of bitcoin addresses and private keys offline as cold storage wallets. In the future, all bitcoin that needs to be stored will be sent to these addresses. This ensures the security of bitcoin
bitcoin mining machine scam is to make money by leasing or selling mining machines the so-called "mining machine" refers to the computer that installs and runs specific software and algorithms. As we all know, bitcoin can only be obtained through long-term running algorithm of computer, and the total amount is limited. Therefore, some manufacturers have launched specially designed and optimized computer procts, known as "mining machine" in January 2018, a mining computer named "Kodak kashminer" appeared at the international consumer electronics exhibition in Las Vegas, which aroused people's attention. But now critics point out that the mining machine plan is actually a fraud, and the publicity for profit is also false precautions: 1. The general computer configuration of bitcoin household can not meet the requirements of bitcoin miner, so it is difficult to earn the electricity cost of a day 2. If you have to use bitcoin mining machine to dig coins, it is suggested to choose a reliable and legal platform to go more steadily. In the legal platform mining, the daily income can be seen, and a certain amount can be withdrawn
I believe there is a fraud in issuing digital currency, but there is a fraud in mining. Unless you buy a "nonexistent" mining machine or computing power, the probability of being cheated is almost zero. Next, let me talk about UTC's past and present lives
So, it's hard to say whether UTC is a fraud, but this model is indeed an innovation in the currency circle. After all, digital currency is getting more and more attention, and it may not become "currency", but it may become "alternative investment goods". Personally, I'm optimistic about this mining modelmoreover, as far as I know, the team behind UTC, as well as the financial and technical support are quite reliable. If it is really a scam, the institutions that invest in UTC will not make such a big battle to cheat people
