yes, maybe later bitcoin will become the world currency if all countries have legalized it, and the price of bitcoin must be more stable because if the price of bitcoin is still not stable, of course it will be very detrimental to become a means of payment.
This must be a means of payment globally, because technology is adequate. The problem is that not all countries accept bitcoin, so there must be a global agreement so that all countries agree. In addition, not all countries have fast and stable internet access, because internet networks are the most important.
