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.
With the transaction fees and the big difference between buy and sell value, it's tough to use our coin to deal with, for now it's better to use fiat
or better to convert your bitcoin to fiat then use it to buy your needs.
though it's a good development seeing merchants accepting this payment process, for sure more will happened soon adjustment will be made
and it will be more easier to transact using bitcoin.
