I have very simple advice. Try to forget about cryptocurrency. The main thing is not to sell your tokens. In the future, there will be growth and it will be possible to make some decisions. And now the main thing do not make mistakes and do not sell. Although I understand that it is very difficult to stop being interested in cryptocurrency.
Yes, we can earn by holding long term but it tooks time to earn, we can't expect because the market is unpredictable if you choose a potential coin then I can say it will totally achieve.
