We have financial systems that are certifiably broken, there are countless ideas about how to fix them, the digital era makes new ideas easy to explore and everybody would objectively be better off with some genuine innovation
yet all we've got is this manic obsession spawned by bitcoin that has no economic objective whatsoever.
If that is "efficient allocation of capital" one wonders what inefficiency looks like.
Bitcoin is a new thing, sitting on the shoulders of the giant technologies we're otherwise so proud of - all us highly paid software industry folks.
But no, it's worthless, it shouldn't exist, it's not worth any further time or effort or research, fuck it off my fucking planet.
It's so weird this attitude so prevalent on HN.
Answer: let's re-invent accounting.
Look the problem is this, as an "exchange", to be profitable you either need to charge fees, or do some sort of fractional reserve, using deposited value as capital for your Exchange's investments.
If you go for option one, then you will be undercut by someone doing option two. The tradeoff being, number two is more likely to loose all your customer's cash.
The value of something is more often than not irrational. This means that there is subjectivity in the value of assets. You can't technology your way out of that. This means that its perfectly possible to prove that you have liquid assets that will cover your present position. However thats expensive to maintain. So you start buying longer term more illiquid assets (think property, commodities, companies, etc) some of these are liquid in a day, others months.
Worse still the value of them depends on how and when you sell them.
So sure you can have assets that cover all your liabilities one day, then due to a re-valuation, not have enough.
Thats not the same as solvent though.
But, all of this neatly misses the point of crypto. If its a practical payment system, rather than an investment, you wouldn't hold your crypto at an exchange. You hold it your self and move it when you need to convert/liquidate.
