>> It never had a real use outside of scamming people and buying illegal shit,
Some anecdotal evidence to support what you're saying.
I work at a large health care company. When crypto and blockchain was getting popular, there was a huge push in the company to adopt blockchain and to a degree, crypto. I'm talking hour long presentations by blockchain companies, videos, and trainings. It was heralded as the dawning age of technology where people can be treated and pay in crypto, while at the same time, all their medical files being securely stored on the blockchain. They pushed it as the next step in 100% digitizing health care.
3 months later? It was dropped. Not just dropped, either. It was silenced throughout the entire company. The sharepoint sites promoting it internally were gone, the videos, presentations, and trainings were all scrubbed from the company sites and resources, like it never existed.
I started asking around and found out the executives found out about several exchanges going under and taking millions of people's money and how blockchain was more of a solution in search of a problem. That combination became too toxic for them to invest and be associated with.
