I don't read any comments here from anyone who uses it as a currency, and yet I personally do. For me it works really well. I don't buy coffee with it, I swap it for cash for that purpose, but I've paid most larger bills with it for more than 2 years. I had a good initial experience being paid with it years ago.
I find it extremely convenient. I prefer it very much now. It is currently my preferred method of accepting payment. I guess I'll just keep using it until it all collapses or whatever.
