Yes, I would agree your words. I was also doing the same thing in the last year. But then I came to know about trading and switched my work.
I worked so much in Airdrops and Bounties. If you would ask me for a favor, I would recommend bounties, because their are so many airdrops scams I have ever seen. My friend Jaddy was working on Bounties, and I, on Airdrops. He earned much more than me, and I also realized it when I, myself, switched to bounties.
