Everything is a cyclic process. People always realise the importance later, atleast the usage have come around earlier. Because, the circulation through gambling have helped the bitcoin market progress and have some real-time usage. Though it is looked as a token developed for gambling needs and illegal transactions, the transition it have come through is really big and not all innovation were able to reach such a status in its short time period.
13 years passed and now what he had dreamt years back have come true. Soon we can expect that gambling is possible only through cryptocurrency. As of now the cryptocurrency accepted gambling platforms are much popular against the fiat based platforms.
A prophecy or vision that has come to realization, the funny truth about Wild thought and ideas is that its always starts off as nothing or something thats seem impossible to achieve but hardwork and persistence pave way to massive and good results just like the way the dream of satoshi to open way to folks on how they can be the banks to their money started as nothing but now the adoption of crypto to the us dollar is growing like wild fire especially now that the banks have continued failing. If there is any means growing any stuff to a rapid growth , i think gambling is one of those means although i wont accredited the massive growth of bitcoin to gambling but atleast it played a major role and today many people are enjoying this advantage, well there isnt a casino yet in my place thats accept bitcoin as a means of payment and thats because of the crypto ban in my region but i believe like you stated its only a matter of time and bitcoin will definitely stand as the number 1 currency and it would be accepted by the government in areas that have shy away from it.
