Xiaobai must see the difference between spot and contract
Spot is similar to stock. You can only buy up but not down. It belongs to non leverage trading, that is, how much money you get in without any leverage. If you buy up and down, you lose money, and when the market goes up, you make money. For example, if the market price drops to 10, as long as you continue to hold it, it is equivalent to that your assets are still there, that is to say, as long as the list is not issued, it may be back to the original. It is only a matter of time, See if you can endure to live, wait three or five years, if the market goes up again. If you go back to 4000, you're not going to lose a cent. To make things simpler, as long as you don't make a single purchase, the assets will not return to zero. It's just a matter of time to see if you can make it.
