Things to come for Waves:
Tidex exchange launch (exchange partnership)
New Dex Gui
Ethereum gateway and i think the chinese yuan gateway
Tokenomica release
Smart contracts and scalability
Also they have recently partnered with Deloitte and introduced the USD gateway.
Its a massive 3-4 months for Waves. I cant tell you how much to invest or what proportion to hold but I think its good you are holding some
