They did but airdrops are also subject to the law of unintended consequences. Sometimes, they might not have the investor pull that was expected from the onset. In the short term, price may dump, and the artificial community created by bounty hunters does not last too long
Can you comment more on unintended consequences? What exactly do you mean?
I believe there is different audiences if you separate Airdrop and Bounty. I know mostly they come together as it is then easier to attract the masses, but I believe a bounty without an airdrop might actually be a better solution. As incentivisation for investment it could be an additional bonus on the invested amount, but not just free tokens to everyone. Thoughts?
