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.
That's actually wise for them. However, most of the bounty hunters are not doing that. By the time they receive their pay, they immediately dump them wherever the tokens are accepted for exchanges. They do not have the patience to hold their bounties and wait for quite a while for their tokens to accumulate value.
we cant blame them mate,sometimes it took them years before the token have its value so whenever comes the value they will sell it right away..and as we know its a 1/1000000 chances that the bounty's value will be higher than what we expected.they were just being practical ..
