People's interest can change in the market. Which is what balances the market. Difference in utilities.
No fud! just reasoning like an economists. Using their mathematical science. You can contribute or share you insights on Pareto principles; Pareto optimal and Pareto superior trades.
Why do people think that it is boring? I mean in order to ask if you could get tired of it, you must think that it is boring, I think it is one of the most exciting things ever and I do not think that it would be all that much of a difference in the end. I believe that we are going to end up with something that would be a bit more like fun thing to do for people.
People will trade more and more, because it's fun, did we get tired of trading in the stock market? We did not, it existed and will exist for times to come, I think crypto is like that too, and people should be happy about that, I think that's an important thing. I get that not everyone may think the same way, but majority of the people think of it like it is a fun thing. When the topic of discussion (in this case trading bitcoin) is this much fun, then it means that people will not get tired of it and that is why it is not going to be tiring anyone and people will not stop doing it at all.
