I participated in the first airdrop IOP (internet of people) and with 500 token iop I received 2200 hydra .. that I sold in the exchange on the discord and from which I got 450 IOP .... with a gain of over 90% doing nothing. Tonight, the second airdrop closes the second airdrop and tomorrow another part
You just got lucky. Usually airdrops are complete waste of time, our only real resource in our possession.
99% of airdrops are made with the intention their 'devs' to make quick money.
You're right 99% of airdrops are not worth the time and efforts put into them but when one stumbles on the remaining 1%, it is usually well worth it. I have been receiving airdrops from Bitsend (BSD) for close to a year now, it's still paying and promises to paying till 2019.
