it all depends on what project you are participating in, if you are expecting a big prize I think it is quite difficult, if there is a worthy project it is always chosen by many bounty hunters and the chances of the reward you get are small. if you are interested you can join the signature slot that I am using right now, this project pays weekly.
The problem with the weekly bounties that pay in Bitcoin or large coins is that they have difficult conditions and a very limited number of participants, and among the examples of these conditions is that your account on BTT needs to received 5 mert during the previous months. I think that with the emergence of the DeFi system there will be good projects such as oikos which I'm working on so far, maybe we will find such this project soon, let's be optimistic.
Yes, exactly as you said. Defi is having huge hype and most of the Defi projects have been successful in this market and are profitable for investors. But there are too few Defi projects to bounty, so far I only see DIA and OKS being successful and we need more campaigns in the near future.
