I don't think bounty hunters are used as bait by campaign owners. It all depends on market conditions. in 2019 indeed almost all bounties are worthless. The project team did not dare to register their tokens in exchange. but for this year, many projects have dared to enter the market because the market conditions are very good. So the bounties tokens will also have a good price or in accordance with the price of the token sale period.
will be interesting to see how this year is going to reveal itself, but first month and a half is good for crypto market, on the other hand, last year was similar up to May/June, and then it got back to basics, however this year have BTC halving and I presume that until the halving prices will go up, and bounties will be worthy
