I used to invest in ISO and make a profit. Recently, a lot of coins in which I invested fall down after entering the stock exchange. I do not know what to do about it ...
If the token falls, there is only one way out - to sell it and wait for the price to stop falling and then you can buy exactly the number of tokens that you had before. Then you can wait for its growth. You have already earned money on the difference in the sale and purchase of a token and you can earn more if the price rises higher.
