Bounty hunters spend their time to promote the project. Time also costs money.
Bounty hunters should not agree to work for tokens of new projects that are not yet traded on the exchanges. Because they do not cost anything and quite often it turns out that bounty hunters work for free.
As soon as bounty hunters start to appreciate their time and stop working for tokens, they will be valued much better.
The problem is that 95 % of the bounties do offer tokens that are not listed on major exchanges. In 2017-2018, I participated in more than 30 bounties, only 1 got listed on binance ...
These days, interesting and good bounties are rarely found...
That's why so many good posters prefer to participate in bounty campaigns where payment is made in bitcoins. Payment in tokens is always a risk, primarily the risk that the tokens of the project will cost cheap. However, sometimes there are really big rewards among such projects.
Personally, I prefer not to risk working for those who pay with promises.
