Maybe what OP meant, those who have invested in bitcoin have indirectly changed their finances and indeed until now bitcoin has not changed the economy in a big way but if you look at the increasingly unstoppable growth of bitcoin, it is possible that one day bitcoin will be adopted by many countries so that it can change the economy in a big way. For example, now we can see like El Salvador which adopted bitcoin as a currency and benefited from bitcoin.
Even if bitcoin adoption becomes more widespread, it is unlikely to have a significant impact on a country's economic development. Does Bitcoin create jobs and income for people? Is Bitcoin given to everyone for free or do people need money to own it...? So it can be said that bitcoin cannot make any significant impact on any country.
Although El Salvador has made bitcoin legal tender, people there use fiat instead of bitcoin for payments and there have been no reports of bitcoin's impact in boosting their economy. What El Salvador is doing is they are investing in bitcoin and luckily they are making a significant profit. But this is not a solution to improve the economy because if bitcoin suddenly has problems and is dumped then what will happen to them?
Of course it's not bitcoin's fault because bitcoin since it first existed has been accessible to everyone, it's just that at that time there were still many people who were skeptical about the growth of bitcoin. But now with the increasingly rapid growth of Bitcoin, it has helped many people, especially in terms of finance. Bitcoin certainly cannot be enjoyed by the entire world's population, this is the same as gold, not all world residents have gold.
There is no denying that bitcoin has helped many people improve their financial situation but not all. After all, gold and stocks have made many people rich but they have never been called the saviors of the world and bitcoin is no different from them. It can be beneficial and help some people improve their financial situation if they know how to take advantage of it.
