1. According to incomplete statistics, there are 166 concepts of
bitcoin, which was first proposed by Nakamoto in 2009. According to Nakamoto's ideas, open source software is designed and released, and P2P network is built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
unlike most currencies, bitcoin does not rely on specific currency institutions. 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 currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity. 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.

2. The nodes of bitcoin are software running on the computers of millions of bitcoin users, and millions of bitcoin nodes are interconnected to form a bitcoin network. Bitcoin node software usually includes the following functions:
1) wallet. It's used to store your bitcoin balance. In principle, as long as you have the private key of your own bitcoin address, you can use your own bitcoin
2) verify the transaction or payment. After receiving the transaction, the bitcoin node will use certain algorithms to verify the validity of a transaction. If you only change the balance of bitcoin in your computer, others will not recognize it. Similarly, your wallet will not recognize the transaction changed by others
3) mining. Core wallet can start mining function through a command to join the mining army, while SPV wallet usually can't (SPV is just passing by). However, it is not the node type that hinders home computer mining, but the rapid development of professional mining machines. Compared with ordinary computers, the computing power of ordinary computers is very small. Mining by ordinary computers is like digging your own backyard with a hoe, and then expecting to dig out gold
because of the demand of bitcoin users, bitcoin exchange was born. The exchange provides a place for centralized trading. People put money on the exchange, and the exchange will match and trade together, similar to stocks and securities. Therefore, banning exchanges does not mean banning bitcoin. Bitcoin network cannot be banned. Bitcoin is sent to the exchange's wallet, and all you see is a balance given to you by the exchange. In fact, you no longer have your own bitcoin. Bitcoin network is global. Where there is a network, there will be bitcoin. After the exchange closes, bitcoin will not disappear, but will return to where it should be.

3. There are many ways to play digital assets, and the modes of each exchange are also different. At present, there are several mainstream models in the market:
1. OTC over-the-counter trading
OTC trading system provides information release places for buyers and sellers of digital assets. OTC market is easy to get acquainted with the previous over-the-counter trading mode, there is no fixed trading place, no fixed Trading rules, and no limited trading form
2. Currency transaction
currency transaction is mainly aimed at the transaction between digital assets and digital assets. One currency is used as the pricing unit to purchase other currencies. The currency transaction rule is also to complete the matching transaction according to the price priority and time priority
3. Perpetual contract trading system
perpetual contract is a derivative of futures cooperation. Like futures, it is a contract transaction, not a spot transaction. After you buy, you will not get digital assets. Development of digital asset trading platform, development of perpetual contract trading system
4. Digital asset mortgage system
digital asset mortgage system is a mortgage investment platform for global digital asset players, on which global players can mortgage certain digital assets.

4. More relevant, you can also do other trading modes, not only currency trading, but also options trading, futures trading, guessing and so on
5.
MFC financing is owned by MBI group. MBI group has been exposed by Guangzhou evening news and hainan.com, and has been identified as pyramid selling by instry and commerce. Therefore, MCF financing platform is a fraud
6. This is not very clear. You can check it on the Internet or on the btc123 navigation. I haven't heard of it in the currency circle for such a long time. I don't know the technology and don't pay much attention to it
bitcoin is a consensus network, contributing to a new payment system and a fully digital currency. It is the first decentralized peer-to-peer payment network, which is controlled by its users without a central management organization or middleman. From the user's point of view, bitcoin is much like Internet cash. Bitcoin can also be regarded as the most outstanding three style bookkeeping system.

7. I suggest that you can buy bitcoin in okex, which is more suitable for novices. You can buy bitcoin in the next app. The operation and security are very good, and it basically arrives in one minute
8. It depends on what type of mine you work in:
1. Excavators are not allowed to be used in high gas and double outburst mines (unless they are explosion-proof). These mines can only use excavators on the ground, which is no different from other construction sites
2. If the excavator is used in an ordinary mine, there are more risks: the most important risk is hydrogeology, followed by the risk of roof rock falling (collapse), and the risk of st
3. If it is open-pit coal mine, the biggest risk is st, which will lead to silicosis
it is suggested to choose regular large state-owned mines, and the safety facilities and security of indivial and township small coal mines are not in place.
