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 ?
I think that 5-6 coins is very little.
I would hold 10 to 15 coins. This will reduce the risks. If some coins do not rise in price, then my deposit will still grow due to the high price of other coins.
Now in my portfolio of 9 coins, but I started to form it recently
