Airdrop can work well with bitcoin because airdrop is a support factor in bitcoin. airdrop can give us free postoken just by filling the data that has been provided airdrop and postoken then we can make bitcoin according price already marketed. With airdrop then bitcoiner can get many choices in finding bitcoin.
Although BTC is a public blockchain, for now, Airdrop takes a snapshot of bitcoin and is very irrational.Because you can think of bitcoin's bloated blockchain, haha.Also, the erc20 token used by Airdrop is very mature and there is no need to take BTC snapshot, personal opinion.
