I have earned a lot in bounty campaign whereas in airdrop only gained a small amount of tokens compared to signature campaign. I love doing bounty campaign because this gives me an opportunity to interact with other people in give them correct information about crypto world in order to help them in their adventure in trading. Airdrop is for those people who have decent knowledge about marketing, in order to maximize their income potential.
Unlike all of the others my experience was quite good. First token that I received from airdrop is ebtc and lucky to trade it on a good amount of cash. Still participating on some airdrop that I think will have a good future. But I focus more on bounty campaign for now, I see a big potential and great income maybe in 2019. I am just holding my tokens from bounty and waiting for the right time to cash out.
