I think it can happen because Energy will update to Gen 3 but Coinomi doesn't support the upgrade, there is already an article link that discusses it. And maybe another factor is the Circulating Supply that is getting more and more, I don't remember how much they issue supplies every month.
Staking rewards are crazy for that coin, if I recall correctly. So with that high a supply, folks probably will dump their stakes as they roll in, hence lowering prices. Eventually (or maybe even now) it will become a problem, and look more like a pyramid coin -- those who got in early and sold during spikes, will have done fine. Those left holding will run into an issue due to simply too many coins out there.
Not saying this as fud nor to scare anyone, and perhaps it'll do a nice run post 3.0. But I recall looking into this one a while ago and it just didn't add up to me ... looked like a coin destined for problems unless they changed their staking rewards, just too many coins being pumped out there.
