I am not sure this is a god strategy, I have 5-6 coins, and try not to keep more than that as it becomes impossible to keep following the coin's news.
Is holding up to 5-6 coins only too risky ?
how many do you hold and what is your rationale for that number ?
when i started trading i dont withdraw my earnings i just bought it with coins i think thats id worth keepin
sadly the platform delisted some so i lost a lot
now i learned that you just dont buy and buy , you have to choose your platform then if its for long term choose a coin thats atleast on the top 20 to be safe
and of course take some profit.
