I don't recommend any of them but you have to use your own time doing it and we've got a section on the forum that has these airdrops if you ever are interested on them.
It's on the Bounties -->
https://bitcointalk.org/index.php?board=238.0There are bounties and airdrops there so it's kind of a mixed up section if you want to check each of them.
Thanks for directing me to the right place man
You are welcome.
Check there every now and then because there are too many of them.
But that doesn't mean that each of them are going to be successful.
