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?Well you can always find new airdrops in this forum. You need to find any website. Many good airdrops can be found here in bounties altcoins. If you are hardworking then you could look for a better one.
