As long as the project is a coin or token, it's clear, I don't think there's anything wrong with holding on. for now there is a large selection of coins that can potentially compete in the crypto market, you can do research on a particular coin if you also want to invest there.
is there any other that can offer instead of coin or token? what does this really impose here ? 
I'm not sure for what you are really implementing here lol.and besides OP is asking about what altcoin to be specific and not for him to be advised what to do or where to buy.
