I like the both projects. But Envion I like more. Envion already raised 34 million at the start of the ICO. It is very cool!
Yeah, the amount of already raised money is VERY important, but WePower has a huge hype around it. Take a look at ICObench. Almost every expert set very high scores to this project.
Most ICOs for now are unprofitable after the release of the coin. I think the most important thing is the way they'll spend raised money.
