It needs innovation..
The problem with most shitcoins today is they lack innovation.. and the ones that are innovative sadly are to complicated for most or swept under the rug.
One notable altcoin is CRE (Credits).. Any BTC user can claim them and its POW that requires coins to be deposited in order to make mining easier.
I would check it out if you are looking for a decent coin to run with in the future.
Honestly though most shitcoins are just wastes of bytes.. very few are worth the BTC people trade them for.
