I would probably stick with stellar, xvg,cardano and power ledger.Believe me when i tell you that these coins especially cardano and powr are going to be pumped in the next coming months or end of year. it will probably reach 10 dollars each
If Cardano will hit 10$, them the marketcap is near to Bitcoin.
I ithink this will never happen.
If you look for a good project with low marketcap you sould take a look at ELIXIR.
