With the way the US is endorsing Bitcoin, so many other countries would follow suit. It is always like, when the US had something endorsed, news of the nations will be popping in, to finally accepting Bitcoin to be legal in their country.
I am certainly waiting for the news from other nations adopting Bitcoin soon since the US president "Trump" has made the news open of how he's going to use Bitcoin as a US reserve. The other nations president we find the need to do the same in the near future, which will eventually skyrocket the Bitcoin price more.
