To be able to land on the spot of 'MOAB' I think it should surpass even the market capitalization of gold, which obviously didn't and not even half of it was filled by bitcoin. This isn't surprising, considering that only a handful of institutional investors' eyes are laid on bitcoin as of late. I don't see how bitcoin can be considered a lucrative bubble compared to the ones on the list, or maybe people just want to sensationalize it and make it look 'bad' from the eyes of the public. Either way, it's far from being the mother of all bubbles; it had its fair share of magnificent runs but that's pretty much it, a rising asset class with a recognition from the worlds' financial magnates and leaders.
