best coins to keep in the wallet that give me the best benefits?
What benefits are you looking for? It sounds like profit and for that you'll want to consider potential price growth as well as looking in to coins that have proof of stake so you can grow your holding over time.
POS gives dividends but it doesn't seem good as you said, because it can be considered as security and then take your own conclusion about that, The coin which can give utility usage will be a very interesting thing dude, This seems true consider about the fact that we have no utility token.
We have utility tokens, some even that have staking. BUT none of them are reaching their true utility yet because adoption is so limited. If you could pick a coin that would reach widescale adoption and live up to its utility then that would be a wonderful investment.
