This jeopardizes the use of Bitcoin as a currency for cross-border criminal transactions which is a large if not majority share of its use case.
So it’s easy to see why its value went down — fewer criminals will want to use it.
Do criminals seriously expect that bitcoin (or any other cryptocurrency) is safe against the wallet being hacked? Hardware/cold wallets have been around for years, so this is more of an opsec issue than a technology issue.
But what does crypto have to do with criminals? Criminals just need to up their op sec game, they know that. BTC dropping is only related insofar as this stupid correlation is getting pushed hard in the media right now.
Criminals are basically the only group making widespread use of Bitcoin as a currency rather than as an asset class.
