I dont think they are asking for too much. They are wiling to give up a cut of thier profit forever.
I'll be investing tonight.
I am in the same boat. The way i see it is this has a good chance to be huge with esports betting and future casino. If all investors roi and are still paid into the future it has created winners no? Investors will be paid forever like you said whats to hate. Maybe the valuation can be tweeked but then again maybe it could have been undervalued this time next year.
