New and old mining machines

1. Bear the depreciation cost of the mining machine for the mine owner

2. Mining machine many platforms can buy ah! I bought a miner on the cube website, which is very useful. You can go and have a look.

3. digital currency mining, we often mention a word is mining machine computing power, such as: Maya D2 Ethernet cloud computing power, Maya X1 bit cloud computing power. In fact, the meaning of computing power is very simple. It represents the measurement of the computing power and performance of the mining machine. Specifically, it represents the number of operations of the overall hash algorithm of the mining machine per second.

4. After searching the relevant information of eco digital currency on the Internet, the first impression is that the currency is basically a pyramid scheme project. The price has been rising, and mining machines, like cloud mining machines, are needed. Most cloud mining machine projects are pyramid schemes
for this kind of project, it is recommended that you stay away from it. The chance of making money is not as high as that of losing money. If you are interested in digital currency, you can pay attention to the mainstream digital currencies such as bitcoin, bitcoin cash and wikilink.

5. Bitcoin (bitcoin: bitcoin) was originally a kind of network virtual currency, similar to Tencent's q-coin, but it has been able to buy real-life goods. It is characterized by decentralization, anonymity, and can only be used in the digital world. It does not belong to any country or financial institution, and is not subject to geographical restrictions. It can be exchanged anywhere in the world. Therefore, it is used as a money laundering tool by some criminals. In 2013, the U.S. government recognized the legal status of bitcoin, making the price of bitcoin soar. In China, on November 19, 2013, a bitcoin was equivalent to 6989 yuan
on January 7, 2014, Taobao announced that it would ban the sale of Internet virtual currencies such as bitcoin and lightcoin from January 14. On February 26, 2014, Democratic Senator Joe Manchin of West Virginia issued an open letter to a number of regulatory authorities of the US federal government, hoping that relevant institutions would pay attention to the current situation of bitcoin encouraging illegal activities and disrupting the financial order, and demanded that actions be taken as soon as possible to completely ban the electronic currency. On January 11, 2017), the Shanghai headquarters of the people's Bank of China and the Shanghai Municipal Finance Office carried out on-site inspection of bitcoin China, focusing on whether the enterprise carried out credit, payment, exchange and other related businesses without permission or license; Implementation of anti money laundering system; Fund security risks, etc. On January 12, 2017, the business management department of the people's Bank of China also entered the trading platforms such as "fire coin net" and "currency bank" in Beijing
on May 12, 2017, a global outbreak of bitcoin virus madly attacked public and commercial systems! More than 40 hospitals across the UK have been widely hacked, leaving the NHS in chaos. The campus networks of many colleges and universities in China were also occupied. Nearly 74 countries in the world have been seriously attacked
from 360 Q & A, I hope you can adopt it~

6. What do you think of it? In fact, the performance is very good, especially today's miners sell some second-hand mining machines with warranty, which are very rable and have good performance

7.

The Chinese name of DK is Tik, which is naturally different from bitcoin

tic coin often carries out false propaganda and takes the channel of direct selling, and the profit model is typical of coin issue, price pulling and coin throwing. Basically, it's a wave of market. In the past, the currency basically disappeared. Bitcoin, Ruitai and Laite, the old currencies, will still be strong after strong winds and heavy rain

purchase method of bitcoin:

users can buy bitcoin, and at the same time, they can use the computer to carry out a lot of calculations according to the algorithm to "mine" bitcoin. When users "mine" bitcoin, they need to use the computer to search for 64 bit numbers, and then compete with other gold miners by repeatedly solving puzzles to provide the required numbers for the bitcoin network. If the user's computer successfully creates a set of numbers, then they will get 25 bitcoins

e to the decentralized programming adopted by the bitcoin system, only 25 bitcoins can be obtained every 10 minutes, and by 2140, the maximum number of bitcoins in circulation will reach 21 million. In other words, bitcoin system is able to achieve self-sufficiency, resist inflation through coding, and prevent others from destroying these codes

extended data

advantages of bitcoin:

1. Complete decentralization, no issuing institution, it is impossible to manipulate the number of issues. Its distribution and circulation are realized through open-source P2P algorithm

2. Anonymity, tax exemption and supervision free

3. Robustness. Bitcoin is completely dependent on P2P network and has no distribution center, so it cannot be shut down externally. Bitcoin price may fluctuate and collapse, and many governments may declare it illegal, but bitcoin and its huge P2P network will not disappear

4, borderless, cross-border. Cross border remittance will go through layers of exchange control agencies, and the transaction records will be recorded by many parties. But if you trade with bitcoin, enter the digital address directly, click the mouse and wait for the P2P network to confirm the transaction, a lot of money will pass. It does not go through any regulatory agencies and will not leave any cross-border transaction records

5. Shanzhai people are difficult to survive. Because bitcoin algorithm is completely open source, anyone can download the source code, modify some parameters, recompile, and create a new P2P currency. But these counterfeit currencies are fragile and vulnerable to 51% attacks

any indivial or organization, as long as it controls 51% of the computing power of a P2P currency network, can manipulate transactions and currency value at will, which will be a devastating blow to P2P currency. Many Shanzhai coins die in this link. The bitcoin network is robust enough. If you want to control 51% of the computing power of the bitcoin network, the number of CPUs / GPUs required will be astronomical

Disadvantages of bitcoin:

1. Vulnerability of trading platform. The bitcoin network is robust, but the bitcoin trading platform is fragile. Trading platform is usually a website, which will be attacked by hackers or shut down by competent authorities

2. The transaction confirmation time is long. When bitcoin wallet is first installed, it will consume a lot of time to download historical transaction data blocks. While bitcoin transaction, in order to confirm the accuracy of data, it will take some time to interact with P2P network, and the transaction will be completed only after the whole network is confirmed

3. The price fluctuates greatly. Due to the intervention of a large number of speculators, the price of bitcoin for cash fluctuates like a roller coaster. Making bitcoin more suitable for speculation rather than anonymous trading

The public did not understand the principle, and the traditional financial practitioners resisted. Active netizens understand the principle of P2P network and know that bitcoin has no legal person to manipulate and control. But the public doesn't understand, and many people can't even tell the difference between bitcoin and q-coin“ "No issuer" is the advantage of bitcoin, but in the view of traditional financial practitioners, "no issuer" currency is worthless
