Both the airdrop and the bounty can get relative coins or tokens, but the key is that they are not all valuable. At present, many airdrops and bounty are very hydrated. It is no longer like 2 years or 1 year ago. Sometimes you may only spend a little time and energy, you can get rich rewards. But sometimes you may have spent a lot of time, you only get some garbage airdrops and bounty. This requires some experience to judge the authenticity and developability of a project!
