Time will tell what these new trend of telegram mining apps will bring, whether it'll be increased adoption for cryptocurrency or devaluation of it. But I think that because of the success of NOTCOIN, many people are rushing into cryptocurrency via these mining apps. Most of then don't even know about the many scams that are in the crypto space, they think that all of them will give guaranteed airdrops reward like Notcoin. This misconception will give room for many of these ignorant people to be scammed and they will end up labeling cryptocurrency as scam. The trend has tremendous increased crypto awareness but I doubt that it will last, especially if they don't live up to the Notcoin expectations.
I agree with your opinion, we'll see the output later on how these new adopters respond, IMO it will be a devaluation because there are too many similar apps, of course they won't pay for all of them, right?
The only thing that is expected after Notcoin (NOT) is Hamster Kombat (HMSTR), they have the most adopters at the moment, even more than the previous adopters of Notcoin (NOT), I think it all depends on how the Hamster Kombat project will be. Good results bring good influence, bad results bring bad influence.
