Tens of thousands of bitcoin

the bitcoin address and private key appear in pairs, and their relationship is just like the bank card number and password. A bitcoin address is like a bank card number, which records how much bitcoin you have on it. You can generate bitcoin address at will to store bitcoin. When each bitcoin address is generated, a corresponding private key of the address will be generated

whenever bitcoin comes into the view of mainstream media, mainstream media always ask some mainstream economists to analyze bitcoin. Earlier, these analyses always focused on whether bitcoin was a scam. Now the analysis is always focused on whether bitcoin can become the mainstream currency in the future. The focus of the debate is often on the deflationary nature of bitcoin
many bitcoin players are attracted by the fact that bitcoin can not be issued at will. The attitude of bitcoin players is quite the opposite, and the attitude of economists is polarized compared with the fixed amount of 21 million bitcoin
The total number of bitcoins is 21 million
in 2009, when bitcoin was born, block reward was 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the block reward will be halved to 25
when the total amount reaches 15.75 million (5.25 million new output, i.e. 50% of 1050), the block reward will be further halved to 12.5. 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 about 21 million

starting from the essence of bitcoin, the essence of bitcoin is actually a special solution generated by a bunch of complex algorithms. A special solution is one of the infinite (in fact, bitcoin is finite) solutions that can be obtained from the equations. Every particular solution can solve the equation and is unique. The process of mining is to continuously seek the special solution of the equation system through huge amount of calculation. The equation system is designed to have only 21 million special solutions, so the upper limit of bitcoin is 21 million

We often hear people ridicule: money is not everything, no money is absolutely impossible. It is undeniable that this is a fact. Some people will choose to work hard and save money. Others will take risks to invest and do business. Others want to earn more money by means of financial management. There are many ways of financial management, such as buying stocks, buying funds, or buying "bitcoin"
then some people began to ask, how can an ordinary English teacher have such a unique vision and catch the black horse of bitcoin? In fact, many of Li Xiao's friends were investing in virtual currency at that time, so Li Xiao also knew something about it. At that time, Li Xiao thought that bitcoin would have room for appreciation, but he didn't expect that the value of bitcoin would be thousands of times, and the number of bitcoin in his hand graally increased from 2100 to 100000, because he was holding the 100000 bitcoin, He became a rich man with a fortune of 7 billion
with so much wealth, Li Xiao can enjoy his life directly without any more efforts, but he didn't do so. He was grateful for everything he got and began to give back to the society. He kept doing charitable activities and helped many poor farmers. Now he has started his own business, At the same time, he didn't give up his specialty and hobby publishing books. Li Xiao's experience along the way is like a story, and we will wish the good hero luck all the time
why
because buying bitcoin early is risky
we can see that bitcoin is a million times higher than eight years ago, but eight years ago, we can't know that bitcoin will be a million times higher in eight years
if you really bought bitcoin eight years ago, bitcoin may have returned to zero and all your investments will be at a loss. This possibility existed originally, but it didn't come out
in stock investment, there is a "market efficiency theory"
it means that the high price of an asset at a certain moment means that it is worth so much money. This price comprehensively reflects all the benefits and risks...
eight years ago, bitcoin was worth so much money
today's bitcoin is 40000 yuan, which is also worth so much money
today's bitcoin is not the same as eight years ago. Just like Fan Bingbing today and 10 years ago, they are not the same Fan Bingbing
eight years ago, bitcoin was not worth money because few people knew it and used it. Today, it's worth seeing bitcoin grow up. But if we go back to that time to judge, it is likely to die, it may return to zero at any time, and it faces too many risks. Maybe a new competitive currency will replace it when it comes out, or it will go to zero when no one uses it at all
at any time point, the ratio of return to risk of investing in any asset is close
for example, at this moment, investing in houses, stocks and bitcoin has its own benefits and risks. So they show different prices
roughly speaking, there is no profit to invest in any target.
when they find that they have been cheated, they often choose to call the police at the first time. The earlier the time is, the better. The longer the time is, the less the chance will be. Try to cooperate with the police investigation . After all, there are many cases of online fraud to recover money
Of course, there are more cases that can not be recovered. After all, swindlers are very cunning. So the best way is to learn more about fraud preventionbecause of the good stock market, there are many wechat stock recommendation groups, most of which are scams. In order to prevent you from being cheated, let's talk about this kind of wechat stock recommendation fraud{ RRRRR}
reflection:generally speaking, swindlers like to pick new people. Whether it's stock speculation or other, new people are the best targets to cheat, because new people don't understand anything, and it's easy to listen and believe blindly. It's easy to be at the mercy of others. So whether we are speculating in stocks or other aspects, we all need to cultivate our independent thinking ability, not greedy, and make money that we can understand
