well, there are a lot of things that differentiate bitcoin / blockchain and Crypto with a lot of the other hypes. But the thing is that the people that are making these accusations have not really taken the time to find out what this is all about. They have looked from above, down their noses and have seen some similarities and shouted: Bubble!!!
but a lot are looking deeper into the matter and are now whispering: maybe not bubble
For a lot of the people you talk of, they will end up very bitter indeed, because while they ignore it, a lot of people will be mastering it, and by the time they finally get into the flow it will be too late for them.
