I made like $200 bucks from the Auroracoin airdrop if im not mistaken... maybe it was another another coin. Well I just got really lucky, I gave my address, I got the coins, and I checked the price and it pumped a ridiculous amount, which I sold I think on Mintpal, or on some now defunct exchange.

I also did the Byteball airdrop and got like $30 bucks... too late, it's paying really low nowadays.

I got some Bitstar too I think, can't remember, but I think I got some on an IRC airdrop in the early days. It pumped pretty nicely too, before it got delisted on Poloniex.
