For me, bounty signature campaign is the best. I prefer bounty even though it takes a long time but I assure you that you can earn a good profit. Bounty is better than airdrop because it is more profitable. This is the right way of earning money tough it takes long time. Bounty has a good project and most of the airdrops are fake .
I totally agree. A signature company can be very profitable. The main thing is to choose a worthy project. It takes a lot of your time, but the income can get very decent.
