In general at me is it is the idea for Callisto's developers and ETC. It is necessary to make exchange of DEX on the basis of these coins (as in waves). It would increase demand of coins and there and the price has grown.
I think Callisto as the project it isn't worse than the same (tron) for example. Just to team it is necessary competent to start a campaign for promotion. Everyones there burning, competitions, airdrops.
