I don't understand the hype with "AIRDROP" coins. It's basically a way to disguise the fact that its been pre mined. Back in 2015 any coin which was pre mined got negative trust straight away and now people are just encouraging it and investing in it.
This is because people want to try different things from PoW, but unfortunately if you don't use PoW, you are then stuck in a sea of akward possibilities such as ICO, airdrops, or forking an existing coin or whatever.
Some projects have good ideas like Byteball, but the way the coins are distributed is a joke. You basically depend on some russian guy that controlls all the supply airdropping it properly, also they change airdrop terms out of nowhere as they go, I like the simplicity and predictability of PoW when it comes to delivering the supply. Nobody has come up with other ideas.
