Hi guys , recently I was interested in tokens with airdrops but what are they finally ? Could someone help me please ?

That's good idea. We start fill google form in an airdrop. Just follow the rule and we will get many coins from the airdrop
Yes thats good but you always need to be active in bitcointalk or you'll miss the airdrop. Just like he mention that you need to fill a form in order to get the tokens they share.
Tokens is actually a payment to any participants in a particular campaign or ICO. It is created by many developers and the name of coin is based also on the campaign name and this coins is being sale and this is actually offered by a signature campaign. Many investors can buy it and then they will hold it for more income.
