Man I'm still angry about Dock.io . Also I would've said that Seele is a must, but I don't know of anybody that made it onto the Whitelist - same with Ocean Protocol.
My answer would depend on what exactly you are looking for, an Ico to flip or a longterm investment?
Best wishes
Seele's whitelist was terrible. They used a goddamn Google Form for their whitelist lol. People hated them for this, at least they delayed the whitelist to make a new one lmao.
