They are both like kings and queens who are very united until now. everyone is still using it today as a means of transaction in all countries. so it's hard for me.
All countries 
, I don't think all countries have implemented this as a transaction tool, because there are countries that are not yet developed and don't have adequate internet access, so that directly the residents of such countries cannot use Ethereum and Bitcoin for transaction tools they, and some other countries also have not implemented real payments, so they can only be used in terms of internet networks.
