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.
Cardano and NEO is the coins that may go up soon.
