Bitcoin remains to be adopted by every country in the world for various reasons. Here are my thoughts on why..
1. Government policies: Most government and financial institutions round the world seem not to want bitcoin cause of the financial freedom it gives to its users. They would want to control and tax the flow of finances of individuals and they probably fear the anonymous nature of its transactions. Some policies even go as far as criminalizing its use.
There are some rules that are different in each country. every government has the same goal basically they want to advance all forms of their prominence but must comply with the norms and rules that they make so as not to make them lose in the end.
Bitcoin is one thing that is independent and its existence will certainly be very disliked considering Bitcoin is something that is very difficult to control.
When they address it, there are actually 2 possibilities, the first is to make peace and go with the flow there as El-Savador and several other small countries are adopting now or are insisting on holding on to this like some big countries.
I think this is quite reasonable considering they want stability for their country with their own ways and rules but for bitcoin the rules will definitely be different because they will not get the authority there because of the decentralized nature of bitcoin
