Airdrop discussions are consuming most of our time. It should be in Marketing not here. This section is one's experience and opinion based.
It was good when they want to get the word to the world. Now the market is getting mature and I do not see how anybody would give free coins anymore unless it is a scam.
the same thing can be said about ico's and they are consuming most of our time.
some projects makes new forms of token distribution. airdrops can be free money or nothing but ico can be good project or scam
