If in the Airdrop you can get $600+, then you can be sure you will get even more in the bounty campaign
and can even triple the results you get through the Airdrop.
You are right. Bounty campaigns are worthy now. I have participated few campaign and I received some money from bounties such as BeforeCoinMarketCap bounty. The first thing is you have to choose campaign very carefully. If you can do it perfectly then of course bounties are worthy for you.
