Hello, it is very easy to conduct airdrop using Waves, that's why the majority of token creators use Mass Transfer option on Waves Platform to attract attention to their projects/tokens. Token distribution is not chasing by Waves, therefore you'd better get more details about currently holding airdrop from the creator of the project/coin. Speaking about Waves Platform, there hasn't been made any official announcement about BTC distribution recently.

Best wishes,
Waves Community manager.
