This confuses me. I make multiple payments every month in bitcoin to fund various web services (i.e. tarsnap, gandi). In fact, I've never had an issue with a bitcoin payment going through. Ultimately, I find the process of paying with Bitcoin to be a joy. I hold my smartphone's camera up to a QR code on my screen, and BAM - payment complete.

Yes, most other cryptocurrencies provide the same thing. But Bitcoin provided it first.
