Absolutely agree with you. I made 100 eirdrops in January, by today about 20 coins have fallen into the wallet, none of these companies have entered the stock exchange
Not all airdrops are fake. Its ok if you only gain a little in airdrops atleast you dont do anything hard to gain those coins. You just register and wait for the coins. It is not a waste of time because while waiting you can do another things like participating in their signature campaign.
Why not wasting? Wasting time research before joining them. Waste time to register because it takes time to research and joining and fill the form. How if we get zero? If only one time or 2 times zero then its no a problem. But how if join 20 and get 19 zonk? Thats what my experience.
