Also, be prepared to be faced with change of rules for the airdrops and perhaps limited spots for participants etc.
I have joined quite a few airdrops but not gotten any tokens yet. It looks like I will be getting my first airdrop after ICO for one of them but others I dont know.
One had 6,000 signups and only 600 will get the airdrop.
Other says my user wasnt in their Telegram channel but it was!
Basically, I am trying to say that participating in airdrops can be quite frustrating.
