PoSTOken Airdrop is also not that easy to participate. For example many people cant participate because of Point 6. of the Airdrop Rules "6.Your Twitter account must have at least 100 real followers before you retweet."
Sad
I don't think 100 twitter followers is an hard thing to achieve..
You can even get it in 1 to 2 days.
Just follow lot of cryptocurrency traders and lovers and I am sure most of them will follow you back.
That was my strategy.
