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.
Most of the bounty hunters don't hodl their tokens that they get in participating bounties. After the bounty program and end of ICO, bounty hunters only wait for the tokens to distribute in their wallets and if the tokens have exchanges, they sell it but few of bounty hunters can hold their tokens 1-5months after the ICO hoping the market value pump. I don't really know if there's a bounty hunters that can hodl their tokens after ICO in a year/years because not all token pump after a year.Thx for bounties! Good jewelry.
