Since it's creation Waves went up at about 6-fold. Just 5 weeks ago he could create the WAAH-tokens for $0.80, and airdrop them to (say) 10,000 people for just $8. Doing the same would now cost $45, which will reduce the airdrop "spam" on Waves.

He will earn them back from the token buyers and dumping with huge amount tokens in his hand.
