2. What do you want to do? It's someone else's business to write programs. It seems that you are already aware of the risks of bitcoin, which means you are smart

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. So as long as bitcoin doesn't have a credible guarantee, beware of fraud. At present, it seems that tycoons are speculation, speculation arbitrage, and then escape the rhythm

The encryption dog is a kind of encryption lock. The encryption lock is a kind of encryption proct which is inserted in the parallel port of the computer. Software developers can check whether the encryption lock is inserted in the interface by exchanging data between the interface function and the encryption lock (that is, reading and writing the encryption lock); Or directly use the tool attached to the encryption lock to encrypt your own EXE file

software developers can set multiple software locks in the software, and use the encryption lock as the key to open these locks; If the encryption lock is not inserted or the encryption lock does not correspond, the software will not run normally

extended data:

encryption lock realizes encryption by exchanging data with encryption lock ring software execution. The encryption lock has built-in MCU circuit (also known as MCU), which makes the encryption lock have the ability to judge and analyze, and enhance the active anti decryption ability. This encryption proct is called & quot; Intelligent & quot; Encryption lock

the MCU in the encryption lock contains the algorithm software which is specially used for encryption. After the software is written into the MCU, it can no longer be read out. In this way, the encryption lock hardware can not be copied. At the same time, the encryption algorithm is unpredictable and irreversible
