good post, will definitly check your brother, would like to ask him some stuff to get the finance guy view point...
I know you said you don't like investing into ICOs, but you should check out refereum man, great ties with twitch(top streaming platform) and fortnite (one of the top games atm), they are still in ico and you can get a airdrop for free, i would post my referral but don't want to be flagged for it...
