The only problem we have right now to use our BTC as payment for everything is the seller or merchants,
There are only few that accepts it and we are lucky if there are some near us.
Bitcoin has been widely used for transaction fees for health or food and goods from other countries. What do you mean, Your country doesn't accept it? What a loss if Bitcoin cannot be used there in terms of making transactions, but hopefully in the next few years the government will make new rules later.
I'm really looking forward if Bitcoin can be very useful for a transaction tool that can be done in all countries. But you have to use Bitcoin in a useful way.
