Coins with real life uses like POLIS or DASH. This will be the future!
I'll agree if you say that Dash is the best place to invest. Also with its masternode, you can gain a lot of money with one month only but you need to have a big capital to do that.
But I just wondering with polis, indeed I can see on coinmarketcap about the coin. It will be good if you an investor of this coin you can make an imagine how the polis is and how potential the coin is, maybe it will be better.
