In the past two days, the price of Bitcoin has reached $8,000 under some favorable conditions. This is a normal change. Whether it is the ultimate scam, investment upstart or investment opportunity depends on the following aspects: 1. Does the volume and price of American bitcoin futures trading match? 2. Good news such as bitcoin trading and mining will attract large global investors. 3. Do the economies of the United States and the European Union support risk preference funds to enter gold and bitcoin? 4. Has the regional political risk calmed down? Everything remains to be seen, and it is too early to draw conclusions.
