Other than that, how does it benefit you to use btc? I mean you need fiat to get btc, and then usually need to take fiat out. So where is the net benefit besides the fees being lost by the big banks/payment companies?
Not always. You can earn bitcoins in various ways or sell/trade something for them. I think using bitcoin is just a great way to buck the current system and use something that s truly decentralized. "Be the change you wish to see in the world". Hopefully one day we'll be able to spend bitcoins around the world just like we would use cash.
