Posting as proof, from now on close the contract function, think carefully, the end of the contract is zero, this sentence is not false. I have been liquidated many times, and the profits I made carefully every time are not enough to offset the loss of one liquidation.
Let's take a look at the historical prices of mainstream coins. Let's not talk about anything else, just say
#SOL fell from 259 to 8
#LTC fell from 415 to 45
DOGE fell from 0.7 to 0.1
How much margin do you have to withstand such a price to ensure that you don't get liquidated?
Buy spot, basically more than half of the coins will double, even if the other half loses, you will eventually make a profit, and the risk is extremely low, at most you will be trapped.
