I think bitcoin is no longer the new currency on the internet, this time in every country many users bitcoin although there are some countries that prohibit the existence of bitcoin, but it does not affect the development of bitcoin is so rapid, certainly many things we can do with bitcoin for transact even maybe someday bitcoin currency will be the second after the real currency
I assume you meant that some countries prohibit the
use of Bitcoin, and not its existence. If I look at a top list 10 of countries that "banned" Bitcoin, then it's as follow -
Bangladesh
Bolivia
China
Ecuador
Iceland
India
Russia
Sweden
Thailand
Vietnam.
It's a list compiled by CCN, but it's obviously a mere click bait list. In most of these countries Bitcoin in its entirety isn't banned at all. I find it very difficult to find an accurate list of countries that have actually banned all sorts of crypto usage. I stumble over all the low content and low research value content, but something really useful isn't available.
