As a non expert and seeing the background I would say - go for it. They play the honest card in a ponzi scam crowded business so at least will get their attention playing the "scam" card. I am not in danger as no floating budgets available but I would try a little one and get some free ones. Heart is a convincing guy as speaker for that.
Summarized - it is for sure a pyramide / ponzi scheme and you have to be quick! If you hold BTC get this Airdrop money and we will see. What I miss or maybe did not see - what is the actuall business model and value behind?
