maybe you followed airdrop that is scam so you don't get any coins at all and it seems the project is just for fun. I see there are too many airdrop that is attract many people to join and some of them can get the coins and then sell it in the exchanges. but for your information, mostly the coins is really cheap of the price when its launch in the exchanges so I think its better that you search another way to earn the coins. you can join in the bounty campaign so you can get the tokens and usually the tokens of the price is more higher than airdrop.
