If ever a technology could be summed up as an answer in search of a question it's crypto. All the advantages it purports to have can already be done or don't offer enough of an advantage to change from existing systems. I used to work for a blockchain insurance startup and the company rode that crypto hype train for two years before the investors finally realised that having insurance backed by blockchain offered no advantages over regular insurance and they were competing with behemoths like Lloyds. Crypto has a niche role as internet cash (assuming you remember to wash those coins and don't leave a trail) but that's about it. Eventually the world will catch on and, when that happens, the only way crypto will survive if it becomes so entrenched that people view it as an asset rather than a currency - which is already how people treat it for the most part.
