bitcoin is a fraud, so we must be cautious in investment and financial management
even if it is called "hard currency", the price of gold will not only rise but not fall. There is no bubble in gold, but the price is too high, there is a bubble, and the bubble will eventually burst, such as virtual currency such as bitcoin. The more general virtual currencies, the closer bitcoin's value is to zero
this kind of currency, which is a purely calculated digital symbol, has no asset support, no financial revenue and expenditure, no cash reserve and no use value. It is only a circulation symbol. Once it loses its credit guarantee, it is a pile of beautiful printed waste paper. Investors should be alert that there is no so-called safe investment in this world, and all investments are risky
the people's Bank of China and other departments issued a document to severely punish the above-mentioned behaviors, making it clear that token trading is not protected by law. With some virtual currency trading platforms turning to overseas, speculative money speculation has also turned to "underground". In the face of continuous renovation, on the basis of continuous strict supervision, government departments should constantly upgrade the means and ability of supervision, and continue to increase publicity and crackdown on popular science, so as to avoid the masses being deceived
extended information:
investing in virtual currency is more of a kind of speculation. Investors should strengthen their risk prevention awareness and identification ability. Without confirming the identity of the other party, they should not be involved in money transactions, trust low-risk and high return investment procts, especially not join the investment and financing group without verification, These are often well-designed traps by telecommunication network fraudsters
it's better to purchase the investment and financial management accompanied by the children, and learn from the official and authoritative channels, and report to the police in time when they are found to be cheated. Properly protect all kinds of account password, identity information, etc., don't tell others easily. Any reference to the need for transfer and remittance should arouse high vigilance and consult with trusted acquaintances

the problem of double spending is that a sum of money can be spent twice, three times and many times. Why has the double flower problem become such an important issue in the bitcoin system
the reason is that bitcoin is a virtual currency. It is virtual, presented in the form of code, and can be copied. Once the code vulnerability is broken, the same bitcoin can be recycled. In this way, the "money" of bitcoin will become very weak
let's think about it. If a sum of money can be spent many times, and you have 500 yuan, you can buy a 500 yuan dress, which can be recycled, and then buy a pair of 500 yuan shoes. In this way, can money be called money
therefore, when Nakamoto set up the bitcoin system, all his technical means are basically around solving the "double flower problem" of
, to protect bitcoin as a kind of currency, its own function as a means of payment
in fact, the problem of double spending is not a problem in our present centralized world, because with banks, the settlement of money transactions is through banks, which is very safe. If you have problems, you can go to the bank directly
however, in the decentralized world, without such a central institution as banks, it is necessary to ensure that a sum of money can only be spent once. How to eliminate the "double spending problem" under the premise of decentralization is a difficult problem
let's just say, why is Nakamoto so persistent in pursuing "decentralization" and asking for trouble? No, he hopes to solve some social problems through decentralization, the most important of which is the inflation caused by the excessive issuance of money by the authority
so, let's sum up his logic: centralized currency issuance leads to inflation - so we need to achieve Decentralization - decentralization will face many problems, the biggest problem is the double flower problem - so we need to solve the double flower problem - how to solve the double flower problem
here, Nakamoto introces the concepts of utxo and "timestamp" to solve the double flower problem
1. If it's a spot purchase, you can see how much the handling charge is, so you can work out how much the selling price is to keep the principal
2. If it's a contract play, it may be related to the leverage ratio, which will also be displayed on the platform, some will automatically calculate, some may need to calculate by themselves, very simple
