The word you’re looking for is bank
This is nonsense. Hundreds of Bitcoin exchanges have collapsed over the last 10 years.
I hear this repeated often. Very short term, sure. But long term, shouldn't your slice of magical internet money pot be worth more simply because there's now less of it in total?
So yes... a majority of stolen coins are for all intents and purposes, "burnt". Will the major exchanges care about coins stolen from a CEX 10 years ago? Probably not, but I guess we will cross that bridge when we get to it.
Of course, it is possible to "tumble" these coins, but it's an arms race between criminals and chain analysis, and while they can evade the analysts in the short-term, the crime is recorded in a distributed ledger for eternity allowing near unlimited opportunity for future review.
While this might change in the future, I would guess bitcoin isn't technically money. It's more like a gift card some people will exchange for real money.
But even a gift card has more protection than crypto lol
It seems like exchanges kind of are counterintuitive for a decentralized financial product (for holding your crypto). One could argue that exchanges that fail when people are selling off a lot of volume might not have a good business model. My naive brain thinks an exchange will make money on transactions so it shouldn’t matter if the exchange from crypto_bucks to USD is different. If volume falls drastically then maybe your operating costs are too high?
