During the last week I bought coins and they almost immediately fell by 10-15%, and today early in the morning I saw how they fell by another 15-20%. How long will it last?., and whether I should sell for what I have. I wouldn't want to be left with empty pockets.

There is no joy without sorrow, just as there is no growth without falling. I also like you every time upset when I look at the price of coins and see that they are today even lower than they were yesterday. But we have to wait. There will be joy when everything starts to grow.
