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.
