at this time selling/buying something except Bitcoin itself seems to me very doubtful and risky due huge instability in exchange rates.
hm. selling/buying Bitcoin itself TOO.
in last two days we had $180 price difference (down) and in last two months - ca $240 (up). this is not good.
if anything goes stable, then it should be fine and welcome option for BTC stability. even vital.
...or someone must "detach" itself from real currencies (dollars etc) right today - then buy/sell goods should go maybe, but does that anyone now?
if yes AND if it works financially - they all are my heroes ))
