For this bitcointalk bounty program, WePool has reserved a lot of MASS Token.
So exactly what is the number? That reward allocation is a joke specially for the signature 1 and 2 campaigns. Total supply of MASS will be 206 million but they can't even allocate a fixed percentages from the total supply. Since it's not pre-mined so why not pay the hunters in
BTC if you are serious about the promotional thing?
