Waves is awesome! Sasha speaks at quite some conferences and knows what he is doing. Waves has, what a lot of others want or want to be: a decentralised exchange. Combine that with the fiat gateways you mention is an unbeatable combination!
Next to that, Waves regularly has airdrops, free tokens ;-) Not bad at all!
Yes, Waves is potentially a great platform for every occassion. Fiat gateways will encourage more people to use Waves :)
