yes, I agree with your writing. everything might happen. Nothing is impossible in this world. but it will not be easy, and it will take a very long time. indeed advances in technology and the internet today already exist in all countries. but in my opinion not everyone can use and utilize technology. there are still many people who are still low knowledge about technology. and they still rely on fiat money as their daily activities. I think it is very realistic for now, if anyone who buys coffee with the money crypto will make the seller laugh. because the seller does not understand about crypto money. but I also believe, in the future, as the growing knowledge of technology and the internet. and more and more people who understand and utilize technology. then crypto money will be more dominant use of society as a tool of any transaction in daily activities.
