If you want a great profit, I recommend Raiblocks(XRB). I put an investment there when the price is $0.25 and spikes in just a few days to $3 and now at $2.5. The coin is promising and for long term. I recommend buying coins with low supply like XRB since it may easily got 2-3 digits of bucks.
Isn't expanse (EXP) better by your criteria, since its 20 times lesser supply, and about same price per coin?
It's not just about the supply. There are too many copy-cat and scam coins which has a lower supply. The XRB technology is unique because it's a DAG like IOTA but XRB is better than IOTA. Raiblocks offers an instant and free transactions. Also the developers are now working full-time for the project. Also I don't trust a coin with anonymous devs.
Expanse devs are not anonymous, and its listed on more reputable exchanges (bittrex and poloniex). They work full time on the project, too. Also, its mineable, not
given away via some shady scheme
