I have been in forex and stock market for more than 10 years
I've been in the stock market more or less since 1999 (never traded forex), and one major thing I've learned is that the more active trading I do, the more I lose. I'm just not that good at it, plus transaction fees eat away at profits. I've become a buy-and-hold investor in the stock market and in crypto as well.
Good knowledge of Forex trading will really help in trading crypto currency as both are almost similar. Buy and hold for a long time is not some time advisable ( though all depends your point of entry) because there some stock and crypto currency you will hold for a longer period and it will become worthless or become less in value as compared to when you bought them.
