For me its a few. Ardor which will be massive one day. Hydro which is growing fast and hope people get in now before they miss the bus. And finally Elixir.
It is pretty fine to go and try out new coins but you must target the old ones first. That way, your profits will be guaranteed and they wont be small amounts for sure. the problem with these small coins is they can die any time or they cant produce as much profit as the holders need them to or they can also turn out to be a scam. Without a large support, it is impossible for any asset to make progress and these coins cant get this either.
