Beyond cryptocurrency, how many other applications have either been built around or shifted to primarily function off of blockchain? This isn't meant as a gotcha question, but it is something that I can honestly say I can't think of any. In terms of cryptocurrency, from my perspective the problem for mass adoption comes down to stability of value and oversight. Why would anyone want their paycheque to come to them in crypto when a few tweets by Elon Musk, lord of crypto market manipulation can turn your 2k paycheque into a 1.1k paycheque? On top of that, for good or for ill the big banks and credit card companies have decades of built up trust in that there is a centralised authority who can ensure that your money is safe. Irregardless of what the reality of crypto and the safety of your money in crypto, the wider public will not trust that their money is safe when there is no one to be held accountable if something happens. Finally, the fact that crypto has, to the wider public at least, been shown to have significant benefits for criminal activity and speculators actively trying to manipulate the markets has painted the entire crypto space as something that the average person should generally avoid at all costs. In theory, I liked the original idea of crypto. But the truth is that crypto was good-intentioned idealism corrupted by selfishness and greed.
