I don't see what's new about their method, other than making an exchange partnership I guess. I'm sure those exchanges will airdrop their tokens regardless of whether they have the partnership or not, or else their users will be unhappy with them. Unless you're talking about airdrop that doesn't rely on users' wallets having balances or something similar. Locking tokens in a staking mechanism is not new either, some projects already do that, especially if they're launching a new chain. I don't think this will change the market in a revolutionary way.
