Re: Is it true that 99% of all airdrops are shitcoins of bad projects ?
From my own experience I can tell from all the airdrops that I know the top projects were only: Vite, Ontlogy, Dfinity. All others were shitcoins 
I have never heard of any of the projects you listed. You can think that I am ignorant, but I am now a very cautious person, because I have summarized the experience from the failure lessons of 2018, this experience is: except Bitcoin All altcoins are likely to die and are not trustworthy.
