Bitsend is doing very well at the moment! They have weekly airdrops and they aren't massive amounts, but the price has doubled recently, meaning they give out $10 a week, and will be giving out free money until 2019!
I don't think Airdrops with lots of conditions attached are true airdrops. If it is Bitcoin related, then ok, but having to hold X of some crapcoin isn't a real airdrop if you ask me, rather just a pump of an Alt.
It's even better when they announce that the point for counting for the airdrop is in the past, so no one can game the system.
but your rank need to be Sr. Member and active in forum. And 10$ per week maybe not interesting for some senior member who had joined forum long time ago
