Hopefully they will airdrop more this time. However i think you are a bit wrong in your calculations. I hope the 'bch' in address stunt was made to maybe exclude their own address as well as some exchanges addresses from the airdrop. Airdropping to themselves and to exchanges doesn't make much sense imo. However the biggest WCT holder changed their address to a bch one, maybe that was Waves's address.

 I have seen about 1m WCT who is not owned by an address with BCH in it so probably your calculations are a bit off with the "100 BCH it will be ~ 0.00001 BCH part".
