im a little confuse of what is airdrop i cant understand how to take a bounty for it .. If you register or Sign up for the form can you earn a coin??
That's how it works.
When a development team (dev sometimes) wants to launch a new project and sponsor it (an ICO or a new Coin) usually they offer free coins.
Is just a free coin offered without any participation for the incoming ICO project. The only thing they do is just a registration for the scheduled date. But some coins aren't enlisted yet in any exchanger. But then, some airdrops coins are having big value in the market that makes others love to join airdrops.
After you register on it some have rules that you have to download their wallet so you can now have their free airdrop for , some airdrop are most of it hold for a long time before it can have a value on the market.
