Here is my experience. In March 2017, I bought different coins including bitcoins for a total of $ 3000 and then did not touch them at all, in January 2018 they turned me into $ 62,000, but I again did not touch them, now my assets are worth $ 10,000 and now it definitely does not make sense to sell them, I will wait for another growth, of course I'm very sorry that I did not record profits in January, but then I was counting on even greater growth, in the future I will not be so greedy and will act more judiciously.
