What do you mean by no return? did airdrops required you to invest such amounts for their free claims?
Honestly, I dont do airdrops and will never be but why you keep on pointing out the "little to no return" thing. These airdrops are all for free and they cant just give you a lot of free money. Youre lucky if that airdrop went high and gets on exchanges but sometimes people tend to complain with what they have been receiving like with airdrops.
True, they are free but not free at all cost. Some do require a bit of time, and I am also giving out my information to the companies.
I am not against airdrops at all and I did some in the past couple months. It is that the on-going trend of airdrops strike me as more of a marketing scheme rather than building a community/awareness of their brand and product.
