I don't think that the "btc is a failed project" opinion should be refuted at its inflated price. As much as I talk about predictions, I'm even less able to convince people with them because if I fail it will be even more embarrassing. I don't like to speculate with naysayers.

But the function of bitcoin has never failed as a means of payment, for some reason I'm more comfortable talking about the success of doing business with a man abroad as easily as I buy candy at the shop across the street.
