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.
But they do not care about it.
You really cannot blame them. Most of us here do bounties for a very specific reason, to earn. I know someone doing bounties because it is specifically the only source of income. The payment for his bounties is the only means to sustain all the needs of the family. So can you blame him for selling straightaway? I think if we want to keep a certain coin/token from ICO, we have to invest in it.
