I don't agree that it is a good idea to use bitcoin for taxi purposes. There are more ways that much better than that for example.... If you avail your own car you would not use taxi everyday. You can loan a car and pay with fiat in order to have your own car in the future. It should be like that because you absolutely handle your own time, your bitcoin or every crypto that you own, then most of the benefits the car will be yours. That's the practical way that I think more better than ride taxi everyday. It seems you are bondage to taxi. So in order to change that buy your own car.
