Also blaming the victim can only go so far
- More infrastructure than ever has some exposure to the internet - Outsourcing at massive scale (probably) makes consistent security screening harder - There are more programmers in the world than ever and so (probably) there are more black hats, malicious hackers, etc - As time goes on, there are more and more aging computer systems, thus (probably) there are more and more vulnerabilities in the wild - As time goes on, systems accrete complexity, thus (probably) there are more and more vulnerabilities in the wild
But yes, I do think cryptocurrency is an important change. Cash is still king when it comes to crime, but crypto does make crossing borders much easier.
Your own jurisdiction and law enforcement have no power on foreign territory; but foreign organizations (state sponsored or not) located there have freedom to penetrate your society and economy. Moreover, foreign governments may deliberately ignore your requests to investigate.
Thanks to technologies and to chaotic reactions to modern day problems (including covid-19 pandemic) it looks like modern forms of independent sovereign states are very archaic.
But it's not victim-blaming to observe that you shouldn't have made it so easy for the thief.
If it's just your valuables that get stolen, then that's unfortunate for you, but at least it doesn't hurt anyone else.
But when other people trust you to keep the safe secure, and are hurt because of your negligence, then it's also not victim-blaming to observe that your negligence caused harm to other people.
Even if you shut down the cashing out infrastructure (exchanges) in the affected countries, it will quickly spring up again in countries belligerent to them. The FATF is the main global body trying to curb this, but my hunch is they will lose this battle long-term.
Imagine if you are on the FATF red list [1] and you announce a free-for all domestic exchange for local spending. It's free FDI.
Add onto that making it illegal to pay ransoms in BTC, then there's really no value in using it as a ransomeware currency. No one is buying it so all you are getting are some random digits on a piece of paper.
Just like how outlawing drugs ended the drug trade.
When was the last time you drank bootleg liquor? Answer: I don't know of course, but for most people in rich western countries I would think the answer is never.
I think it just depends on the sort of people you choose to spend time with.
If you decide to mess around with a large fractionating column though, do read up and make sure you have a full conceptual understanding of how the chemistry works. Even seemingly benign chemicals can be extremely dangerous to ingest or handle once concentrated. (For example, vinegar. Dilute acetic acid makes for a good salad dressing. Above 90%, contact will leave you with severe burns and scarring.)
