Well, Cryptocurrencies are part of said new era. They aren't strictly a problem that made things worse: they're a technology that comes with tradeoffs. The cat is out of the bag and we have to design around technologies that are here to stay in whatever capacity. Distributed, cryptography-based currencies/tokens are one of those technologies.
Crypto has been an awful development in many ways, but I happily welcome it when it has made malware so much more benign to me. The last malware that affected me personally was a crypto miner worm, and the one before that was a crypto wallet stealer, neither of which affects me at all as I don't meddle with crypto.
I don't know the statistics, but it seems like it's way more profitable for the grifters to target other grifters instead of taking over my machines and extorting me. Or maybe I just got lucky.
Yes, on the one hand, they enable a lot of shady illegal business, but in the other hand, they also destroy the environment while doing it, so it's really a toss up whether cryptocurrency is good or bad overall!
