Earlier quoted context omitted.
Was ransomware really not a thing before Bitcoin?
It may have, but crypto allowed it to become truly scalable. Before, you had to coordinate with each of your victims about how to receive the ransom while trying to evade the authorities. Now you can just take over a random machine, paint a Bitcoin address on the screen, and voila, you're done.
And before cryptocurrency was big, it was shady credit card gateways in non-friendly jurisdictions. You cannot blame cryptocurrency any more than you can blame onion routing, encryption or the internet. It’s all just tech that is evolving and getting more efficient.
