So many confusing, contradictory statements in this post.
You can't really equate the housing bubble and a bitcoin bubble except in that they are both bubbles. Houses are not purchased by anyone because they make a good type of money. The idea that something needs to be fungible, divasable, and mobile really only able to mediums of exchange (usually money). No one should buy a house because they think it makes a good medium of exchange. You buy a house for tax purposes, as a place to live, or as an investment.
The housing bubble was much more complicated than you are making it out to be. First off houses were never monetized, it was the mortgage on said house that was monetized. This might seem like a semantic difference but it is important. During the housing bubble investors weren't buying houses as much as they were buying streams of income (ie mortgage payments). No one really cared about the houses actually underlying the CDO's all they cared about was the yield and the rating(ratings which we now know, and honestly should have known then, to be flawed).
Also you cant say that bitcoin is a bubble because it started at 0. Every asset theoretically started at 0 that doesn't make every asset in a bubble at all times. A bubble is more accurately described as a rapid expansion of something (usually credit) which results in risk assets being bid up to levels that are not justified by underlying realities. Take the dot com bubble for example. Interest rates were super low which allowed for the expansion of credit (Thanks Fed!) thus you have investors with tons of capital that needs to be invested, this capital chased what was hot (tech companies, especially those involved in the internet) and ignored the value proposition of those companies. Thus you had companies who were hemorrhaging money and no plan for getting into the black with valuations in the stratosphere. No one cared about the fundamentals, they had cash to spare and just threw it into what was hot (ie what other people were investing in).
I could go into more depth, but I should really get back to work
I think you are either failing to understand or translate what a bubble is. Just because something is worth more than it was yesterday doesn't necessarily make it a bubble. Usually it is a central bank "printing" more money allowing the price of assets to rise higher than they would otherwise. The beauty of bitcoin is that it avoids this problem. It can still experience volatility of price due to fluctuations in supply and demand however.
