If i may but ask a single question then it's will be like this, has there been any change or improvement from countries yet to adopt bitcoin over 50 years,

Bitcoin is only 14 years old why ask an impossible question?
aren't they the same till now, nothing has changed about their economy yet we have El-Savador which has begin a kind of Satoshi's mindset by giving a new approach to how it can encounter this change, this is just barely a year plus and we expect to see the results like that of a sudden ponzi scheme right? With that El-Savador is rocking well with it adoption and lives and economics are changing for good gradually.
which is the Ponzi scheme? Can you clarify? As far as I know, it will take years for the economy to develop. Not because today they implemented Bitcoin adoption, next year the country will be rich. It is a process, not magic. So we have to wait longer to evaluate how Bitcoin changes a country's economy. We have seen how Bitcoin alleviate the kind of living of an individual, I bet in due time we will se how a country progresses because they use Bitcoin.
