There are a lot of airdrops going on that give you free tokens for just leaving your email and ethereum address. OMG, Qtum, Stellar and many more were airdropped for free.
The only website I found is
http://airdropalert.com/ and it sucks. Many current airdrops are not being listed.
Does anyone have a better one?Airdrops can be seen on the altcoin marketplace thread along with the bounty programs. But in my opinion, it is better to participate on bounty programs than airdrops because not all airdrops are paying and the rewards are just limited unlike in bounties whereas there are many campaigns to choose from which would result to bigger profit. So if that is still your choice, it would be depending to you.
