I'm not surprised to see that there are still people who believe that it's all a bubble about to burst.
That there are people who know that it's all a bubble already bursting shouldn't be surprising, since it's been proved by confirmed math and science.
I beg to know more information about these people who have proved that it's all a bubble. I'd like to know what part of math and science is proving that Bitcoin is a bubble, about to burst. Despite rumors and assumptions, I'm yet to see any solid evidence, as you're mentioning.
On top of that, you didn't answer my question regarding where you're standing on this forum, since you don't sound like a Bitcoin supporter.
