bitcoin trading platforms include Mt. goxmt, bitstamp, bitcoin China, bitcoin trading network, fire coin network, etc
mining is the only way to obtain undeveloped bitcoin, which needs to purchase professional mining equipment for mining, which is called mining machine in the instry
bitcoin miner obtains bitcoin through a lot of calculation through hash algorithm. As we all know, the number of bitcoin is constant, 21 million. As time goes on, the number of miners increases and the number of miners decreases.
the difficulty of bitcoin system is dynamically adjusted. Every 2016 bitcoin is g, an adjustment will be made, The adjustment is based on the block time of the previous 2016 blocks. If the average block time of the previous cycle is less than 10 minutes, it will increase the difficulty. If it is more than 10 minutes, it will rece the difficulty. The purpose is to ensure that the system can output a block every 10 minutes, so the difficulty adjustment time is about 2 weeks (2016 * 10 minutes), that is to say, the output will be halved every four years, And the difficulty will be adjusted every 14 days, so the general trend seems that the output of mining will be less and less
2. Purchasing power for bitcoin
after the prevalence of mining, there are some bitcoin mines, that is, multiple mining machines are concentrated in one place for mining, unified maintenance and management, low electricity price, to rece the cost of mining
the most important parameter of bitcoin mining machine is computing power. The higher the computing power is, the higher the output will be. In the difficulty of bitcoin mining, how much bitcoin can be g with 1t computing power is also used to measure the current difficulty of mining. Therefore, some mines will directly sell computing power to users to dig coins. In this way, the mining risk is relatively lower, and there is no need to buy mining machines and equipment, and no need to maintain them, The maintenance and management of mining machine is relatively troublesome for Xiao
3. Reward for bitcoin
with the rising price of bitcoin, bitcoin has gained more popularity than before, and its position in virtual currency is also unmatched by other currencies. There are some real procts of reward bitcoin mechanism in the market, and cat disk is one of them< The simplest way to get bitcoin is to find the person who holds bitcoin to buy bitcoin, which is equivalent to buying goods. But bitcoin is not required by everyone. Therefore, it is necessary to find the person who holds bitcoin and carry out direct transfer transaction. At the same time, there are certain risks, The other side needs indivials to grasp whether they are cheaters or not, so I don't recommend such transactions on the basis of not being acquaintances or not having certain trust
2. Online trading
there are many trading platforms for bitcoin, large or small. At present, the relatively large and well-known trading platforms are Huo coin, coin security, okex, uto market,... And so on. These platforms are more convenient and safe as three-party guarantee transactions, and the only risk is platform running, But the possibility is relatively small, but some small platforms are not without security
paper money and bitcoin seem to be the same. First of all, you need to understand that bitcoin is not a virtual currency. Money is guaranteed. Paper money is guaranteed by national credit. Even game currency is guaranteed by the company, stocks are guaranteed by the company's asset revenue, and bitcoin is nothing without guarantee. Theoretically, everything can become money, but only theoretically. Shells used to be money, but now do you buy a few bags of shells? It's not because people think it doesn't guarantee that you can buy something useful
so as long as bitcoin doesn't have a credible guarantee, be careful of fraud. At present, it seems that tycoons are speculation, speculation arbitrage, and then escape the rhythm
in addition, no country will allow the existence of bitcoin, which is equivalent to the ancient private coins. The dominant position of the United States depends on the US dollar. The United States has no tolerance for the free exchange of other countries' currencies. The ultimate sign of China's rise is the full convertibility of RMB
virtual currency is the trend, but not bitcoin. It can be said that the probability of bitcoin becoming a currency is 100 times smaller than the first prize of the two color ball. I hope more people don't become victims
people who have been cheated will make up all kinds of lies to cheat others< br />

If you use three words to describe the latest bitcoin, it can only be three words & quot; It's going crazy;. On February 19, the price of bitcoin reached a high of US $56000, with a total market value of US $1 trillion{ RRRRR}
coupled with the global popularity and high liquidity of bitcoin, long-term holders believe that bitcoin is an ideal medium for long-term wealth storage and will appreciate over time
how does bitcoin work? In the bitcoin system, the way money drives is not the digital transfer of cash that most people imagine. When Alice remits money to Bob, Alice's process is like recording on the account book that everyone sees that she transferred $1 to Bob. If Carol wants to charge Bob a dollar, she can see from the same ledger that Bob does have a dollar
Bitcoin is a kind of encrypted digital asset protected by cryptography, without the participation of centralized institutions. It has been running steadily since 2009 and has become one of the important investment targets of global investors. Many investors are very interested in bitcoin investment. The entry process of bitcoin and some investment procts is slightly different. The address of bitcoin blockchain is decentralized, so there is no account opening step. However, purchasing Mai bitcoin with bitcoin requires the assistance of some third-party platforms
at present, there are relatively large platforms in China, such as okex, fire coin and coin security. I have been in and out of money for many times in these platforms. Let's introce my experience of buying Mai bitcoin in these exchanges.
before the introction, I need to explain one premise: the security of Mai bitcoin is divided into two aspects: one is asset security, which basically won't cause any problems when I choose the three major domestic exchanges; the other is capital security, in other words, Is to rece as much as possible with the flow of black money bank card transactions. Because it's easy to freeze their bank cards, each exchange has a different strategy
1、OKEx： https://www.okex.me/buy-crypto/cny
okex is the exchange that I use the most Mai currency. I have been in okexmai currency since 18 years. Most of the time, I have had a good experience of Mai currency. I only encountered the problem of freezing okex account (not bank card freezing) once in my impression. However, OK customer service also helped me understand the freezing process very quickly. This is my first contact with OK customer service, Good attitude and high efficiency< it can be seen from the side that okex has done a lot of work in the prevention and control of black money. Moreover, in recent years, there are few card freezing incidents in okex. Today, the black money in the exchange is increasingly rampant, okex has done quite well
in terms of user experience, the function of one click Mai is more suitable for Xiao. When using this function, you don't need to select the businesses that meet the standard in the list of businesses. It's more convenient. At present, when you do activities, you will get a 20 yuan reward when you buy Mai for the first time
in addition, okex is a first-line exchange with a large user base. Mai currency supports wechat, and ZFB buys Mai with zero handling charge. If you've just come into contact with bitcoin, it's a quick and safe choice in okexmai
However, the weakness is that okex has little support for foreign currencies. Except for RMB, only the Vietnamese Dong and Indian Rupee have depth. The Mai currency entrance of other countries' currencies is only the interface of other cooperation platforms2 https://www.huobi.com/zh-cn/
the exchange's legal currency trading plate is deep enough, and there are many powerful businesses with good experience. Support the purchase of Mai bitcoin with multi currency. In addition, the process of making Mai coins is relatively smooth and can be completed in a few minutes
however, e to the good user experience of fire coin, black and gray procts will also choose fire coin as a channel for money laundering. fire coin has been updating its risk control strategy to intercept black money accounts. However, at present, it seems that the effect may not be so good, and the freezing card incident continues. Friends who pay close attention to the digital money market may understand that a large-scale freeze occurred in early June, and many users' bank cards were frozen. Therefore, we should be a little more cautious when using Mai coins on this platform, try to choose the ranked merchants, and rece the probability of being frozen.

the trading plate of currency security legal currency started late, and the accumulation was not enough. Frankly speaking, the depth and experience of legal currency trading is quite different from that of okex and fire currency< Strong>, especially the t+1 strategy of currency, which is Mai currency, will make complaints about money in a day. This system has been thrown into the trap by too many people, because this is obviously a "one size fits all" strategy with insufficient technical capability.
however, even if there are many slots, coin an is slightly better than the second and third tier exchanges in terms of asset security. Users who trade in coin an can also try to buy Mai bitcoin in coin an
finally, based on the above factors, it is suggested that okex is the first choice for Mai bitcoin, fire coin is the second choice, and coin security is not recommended

if the threat of extortion is violence, the perpetrator claims that it will be carried out in the future; The threat of kidnapping violence was implemented at that time and on the spot. The perpetrator of the crime of extortion does not abct the victim to hide and control, while the crime of kidnapping should abct the victim to hide and control
extended information:
the constituent elements of the crime of extortion:
1. Subjective elements
this crime shows direct intention in subjective aspect, and must have the purpose of illegally extorting other people's property. If the actor does not have this purpose, or the purpose of obtaining property is not illegal, for example, the creditor uses threatening language to urge the debtor to speed up the repayment in order to repay the long overe debt, it does not constitute the crime of extortion
The object of this crime is a complex object, which not only infringes the ownership of public and private property, but also endangers the personal rights or other rights and interests of others. This is one of the distinctive characteristics of this crime which is different from larceny and fraud. The object of this crime is public and private property. It's said that BTM batcoin has changed its name to btme now. No matter what it is called, it can't change the business of cheating investors. Now it's just cheating others to invest. This is a fake disk (a pyramid selling coin fraud project packaged with blockchain, which can charge phone charges and have business success. These things are for you to buy on Taobao. They can cheat you to invest money and connect with mainstream currencies, As long as you have money, it's better to go to the exchange and buy directly. It's no more than letting the little white who doesn't know to take over the plate. The currency has become a flood. It's bullshit to go to the trading platform. A fraudster plays with blockchain and virtual miner for pyramid selling. Your real gold and silver will soon be exchanged for a pile of useless numbers.) pyramid selling currency: in the guise of blockchain technology, the technology is far from the real blockchain principle; Not to solve, optimize or change a business pain point of traditional instry as the purpose; The token is not released through the smart contract of Ethereum, and there is no formal trading platform for digital currency, most of which are traded through the platform built by the project party; Promise to rise but not fall; When you pull your head in, it pays off< The suspect crowd financing unpunished by br / > about the BTM Bart currency fraud group, the mutual help disk and the crowd raising. Finally, the criminals played the block chain and the virtual mine pyramid sale. Now the fraudsters are still at large, and the public security organs are seeking the suspect of fraud to recover the losses of the injured netizens.
