I am pretty certain about Raiblocks. (XRB). Please quote me on this one, it's gonna be a top 10 coin by the end of march.
Right now it's not on any major exchange, but Binance are currently in the process of putting it up on their exchange.
They have a very hard working team.
Also, there is a rebrand coming up, mobile wallets and a much better desktop wallet being developed as we speak.
