For a long time I collected these tokens from the bounty+airdrop. All tokens fell terribly after ico. It is curious how long you have to wait when they grow up. maybe i need just wait 100x)))
It would be really hard to know to be honest I still hold some of my bounty reward and airdrop/Selfdrop tokens .And I don't know if they could still have a value ,We couldn't predict what would happen in the future so we couldn't know if they would get a value or just be worthless .
