I generally stay away from ICO airdrops (well 99% of them).Cos most of them are scams or even if they are not..they are just shitcoins ,luring bounty /airdrop hunters to pay peanuts for free publicity of thier projects.Some of them don't pay.Even if some projects pay after 3 months,by the time the coin will be trading 90% down and you will end up in small change..NOT WORTH THE TIME
