Some people just participate in the bounties and wait for few years. they don't sell their bounty rewards for low fiat reward. Ironically those people become FIAT millionaires. 
Thx for bounties! Good jewelry.
Seen Some that make a good fortune by hodling their bounty rewards for a while.Thx for bounties! Good jewelry.
And i personally have seen some, that it spike at the beginning and hit the bottom sooner after its released. then wasnt able to come back.
Yes you could refer it to a jewelry. but not all the bounties is as successful of others though.
however its quite worth the shot to join some of it,you might not know.
