Bitcoin will have that function once that the lightning network gets released, that is probably the only thing that we are waiting for.
Just think about this; when it gets released, we are going to be able to send money for less than $0,50 worth of fees, it is amazing.
This will really make bitcoin a real currency that can be used at any time, you can not buy a coffe with bitcoin anymore because of the fees, but with the LN activated, it would be possible.
as regards the high fees at present, I thought the idea of bitcoin was to use in place of dollar(whatever).
How can I buy something for 10 dollars and pay more than the value of the transaction in costs
What she's saying is exactly, with the current fee, bitcoin does not have any chance to put it into practice. Therefore, the lighting network is really essential. It is a prerequisite for bitcoin to continue to be used, or any similar remedy that can make the bitcoin fee less than $ 0.5.
