Starting with Auroracoin, a lot of coins aimed to perform an "airdrop" and distribute their coins to certain groups of people. I am wondering, have there been any successful airdrops? If so, how did they accomplish this task? I was trying to follow these at some point, but I have never heard of any coin pulling it off.
I remmeber there was BitcoinTalkCoin - the one with BCC ticker, in fact there were few sharing the same idea). They successfully "airdropped" the coins to BTT users, registered before the coin anouncement. I received some myself :) although it was pennies, you can say that the mission was accomplished.
From what I can gather, there were a bunch of people who were able to claim auroracoins through the airdrop using SMS/Facebook based on various forums and social media outlets. In that sense the airdrop was successful. But who knows how many of the airdrops were legitimate. For all we know, most of the airdrop might have gone to the creators of the coins so they could cash out. I haven't seen any evidence against this.
Any airdrop that is targeted towards a local population is going to be difficult and costly to pull off because there is no way to easily verify people's identity. Furthermore, how can you verify that the coin's creators aren't claiming the airdrop to themselves? In my opinion, the creator of these coins are using "airdrops" to build up hype and don't really have any practical way of handling the airdrop. Or worse, they fully intend to claim most of the coins themselves and sell it off before it crashes. In a sense , it's an age old pump and dump scheme applied in the alt coin arena.
Byteball and Stellar did quite well. Byteball is new and the marketcap is already $100M. You can find details here https://wiki.byteball.org/airdrop
