I used BTC for two or three transactions and it went well, but that vendor didn't last long. And I'm glad I spend every last BTC with them before they went underground with jacked up prices, it made no sense, I won't mention the vendor but I think we all know who I peak of.
I hope Coinbase closes my account, I'm done dealing in that currency or whatever you want to classify it as, it's just a soul sucker of a PITA that you have to work at it just keep it sustainable, that's no fun.
I'm done with BTC, the buying, the market fluctuations, hardly any vendors I know of use it. I'm happy that some people are smart enough to figure it out and make it work for them, but to me it's hard enough placing an order and hoping it arrives.
