the airdrop for me its super profitable to gained money, even its all free but you need also to support them, what i mean is if you buy some token or coin for better,. i know they dont yet if they success the project i just suggest its get to support them, even its small money you spend in that project but soon your spend money to his project your profit make 3x income.
I think airdrop profits are completely about luck. Many of the new coins are born dead, unfortunately.
I think the best thing to do is that, not expecting great thing from the airdrops. Because the most of them are just waste of time.
Yea Airdrop is also depended on your luck, most of the airdrops are fake but your good luck some airdrops will give you a good profit, Like Bitsend and Deeponion, etc. If you check thoroughly, a vast number of airdrops are coming, but only a few airdrops are successful remaining all fake airdrops.
I wish I had heard about the airdrops of the coins which you said. I hope that the number of the coins which will reach good valuable prices will increase in the future.
