I do believe that a lot more countries will come on board to accept cryptocurrencies once the regulations becomes clearer.

Countries are just watching japan and other countries like Singapore and Estonia in how they regulate and use blockchains and allow public cryptos. When more success stories emerge, we will see more countries jump on board.

The tipping point will be when countries start to issue crypto currencies and are able to successfully demonstrate the benefits.. then we will see more countries come on board.
