airdrops are free money. some airdrops distribute a good amount coins through airdrop but some others distribute very less. most of the airdrops are distributed after ICO, so you may need to wait 2-3 months for getting it into your wallet.
And if you have time, you can start attending bounties, bounties pay significantly higher amount compared to airdrops.
But there are also bounties that do not pay. 3 months work and then no reward. Or they give less or they do not give you anything. or the devs run away with the money. All risk.
Yes yes. there are even ICOs that took investors money and wrote "pe*is". So even if you do it all after a great research, all depends on your luck
Lol I want to see that!
