I don't find any problem in using bitcoin at a moment, as I am only using it online and I am very much satisfied with it and if I have to buy something in real world then I don't hesitate in converting it to fiat.
Yes you are lucky not to have problems in bitcoin. I myself have experienced delivery delays in bitcoin so delayed until many days. It was very disturbing me because I badly needed funds in quick time. Maybe it's a matter of bitcoin have ever experienced.
I too have experienced it. but today I already know the problem. when the delivery fee which I use very small. it's very influential.
and until now I have never experienced a longer delay in delivery.
