I remember there was an insane flurry of speculative investing during the dotcom boom in the late 90's, and then it all crashed. Reminds me exactly of crypto. I wouldn't touch it with a 100-ft pole. Over-speculation almost always ends in disaster.
The hype is all about FOMO. People who just got in, need more people to adopt or their investment isn't worth it.
Typical pyramid scheme. At least with Real Estate, Art or Gold, you have something for your efforts.
