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.
the reason they do not accept it is due to regulations and high fees in case they have no problems with regulations. In my case, for example, I have been using bitcoin as a means of payment since 2017, but I make payments to people in my country when I want something they have, I also buy cell phone recharges. But my dream was one day to be able to buy food, pay water and electricity bills in my country using bitcoin or some altcoin. unfortunately this is a distant dream, years go by and I don't see any progress in that direction.
I have heard and read a news here in our country that there are some grocery stores which already accepted not only bitcoin but also ethereum, doge, cardano and other altcoins in exchange of goods.
people from the USA and Europe will be able to buy a lot thing using bitcoin due to the fact that they are technology-friendly places, africa where there is a lot of corruption and retarded politicians it will be very difficult to be able to buy anything using bitcoin
