Hi guys , recently I was interested in tokens with airdrops but what are they finally ? Could someone help me please ? 
I think everythings has been said already and i have nothing to add on,what i can make is an advice,that you must be aware about airdrops because more than legit is a scammer,more of them are just getting our email and use to add on their social media sites that they can use as campaign materials for some projects.
