> it's too technical to be used casually In casual use with your mobile phone, you are shown a QR code, scan it, tap "OK", and it's done. Not that technical. Billions of people with smartphones could handle that perfectly. You're right about transactions being slow and expensive, and that is certainly a much bigger problem. That and the fact that there are still very few places accepting it.
> That and the fact that there are still very few places accepting it. This is one thing I don’t get. In countries like China and India (to name the two countries I know about) mobile payment apps are ubiquitous. You go in to a shop, scan a QR code, and boom your payment is done. This is what crytocurrencies promised, but instead more closed apps came to fill the market. What happened?
Bitcoin Core betrayed the original vision of Bitcoin and hotwired it into a high-cost settlement system. The average transaction fee in Bitcoin is something like $38, which is more than the average weekly salary in many countries.
I believe that cryptocurrency will eventually attain mass adoption. The timeline has been pushed back a few years though because the main network has failed.
