Out of curiosity, how many members on this site use BitCoin?
I personally ONLY use BTC because a couple reasons, well, you never have to worry about payments being reversed, if you sell items you can profit if the price increases (although right now it's low, the price will begin rising soon), and simply because you can shop anonymously.
An annoying thing about only using the currency is due to many shops not accepting it, but you can always exchange to the shops preferred currency if you truly wanted something.
Tell me if you use it or no, and give me your reasoning.
