I decided for myself that if I want to sleep peacefully and not waste my nerves constantly looking at the rate of a particular cryptocurrency, I just bought it and wait for the price level that I had planned for myself. When the moment comes I will just sell and then I will think about where to invest next. When I bought bitcoin, it was much less than it is now. When I sell it, it doesn't matter, I aim at a profit several times higher than my investment, so I am patient and calm.
