Well, first sorry for my initial post towards you. It looked spammy, it seems you are not a 100% spammer after all
About provably-fair games, it is just a buzzword. Why people who re going to lose need something that is provably fair? My experience with mind of gamblers is they need always an excuse for their habits. E.g. the endless chats how some online games are rigged are in fact the thing that keeps gamblers play and lose even more. Gamblers are weak people who look for excuses. We need provably-fair business, but not provably fair gambling I believe.
I absolutely hate bitcoin doomsayers, but let's be honest. There are much more scams in crypto per transaction than in fiat from all angles. The code is law feature means that the reality is hard. In opposition the fiat and centralized reality is soft and much more idiot-friendly. And nowadays we are all idiots.
So the crypto concept is best as protection against expansional state monetary policy. For day-to-day transactions some layers over the top of crypto will have to be made and even after it is done, that system will be still far less idiot-friendly than recent system with credit cards. In other words, the advantage of bitcoin is really NOT for average individual that your balance is just a password. The advantage of bitcoin is that it can not be melted along with something from thin air. There will be always some human factor in crypto and it will be much more critical than by the soft cash.
The thing is that for now unless you live in Venezuela or Argentina or so, you do not see yet how crazy the monetary policy can be. How people store their wealth in properties that have so high value that they can never pay off, or how cars rise in price as they are worn out. Let's see how Brexit plays out.
