I believe more and more countries will be starting to consider accepting bitcoins as a mode of payment for goods and services, this would surely result in a huge demand for bitcoins in the future and it might cause bitcoin price to rise higher. But bitcoin still need to solve the problem which are slow transaction speed and high miners fees to encourage more users to use bitcoins for purchasing small items.
Not only bitcoin can be accepted, but also some altcoins are already accepted as a payment method. Like OneCoin, which already exist in a lot of countries.Has a lot of merchants and they are using it at the moment to make some transactions for their goods
I heard a lot about Onecoin, but I'm not still buying it. It could be more country will accept bitcoin as payment scheme, but I believed we are still years behind from it. Unstable price, high transaction fees and slow confirmation are the reason that we won't see it happening in the near future. Bitcoin now is not for micro payments. Its beginning to used as investment instrument or even store of value.
