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.
Not all bounty reward will be profitable if you sell it. Most of bounty token are just starters. Yep, there are some ICO that are hard working, determined and very loyal to their customers or investors, some are not. I have been joining bounty since last year and I always remember my token reward, nothing happened after a year. I am so blessed because I sold it immediately.Thx for bounties! Good jewelry.
