Well I do think the airdrop model was incentivize people to buy EOS.  Stacking more EOS has been a very big thing for me because I continue to get airdrops and were given coins on sister chains like Telos which I sold for more EOS.  Then I'm able to utilize the REX (Resource Exchange) to gain even more EOS and then now I'm able to vote for these proxies that are voting for Block Producers who are paying money back to voters so I'm getting even more EOS.  It is pretty insane actually.  Eventually I feel it is going to pay off in a very big way when people flood back into crypto in 2020 and 2021.
