I personally am %100 in altcoins i dont know if its a good idea but so.
If you are experienced, it is a good idea. Given that the market has come to its bottom again. I think this is not a correction, but the fact that many holders are just tired of holding tokens.
I believe in their future, and I invest in altcoins because one day they will make me rich.
Some of the good cheap altcoins to invest today would be Cardano, Stellar, NEO.
