Hello,
I'm just interested if is it possible or there is some catch. I see that price of BTC on stocks is different (of course) but the difference is big enough to make money with just buying on one stock and selling on the other one. So my Q is what's the catch? I already checked fees and still it's should be ok.

I've never trade BTC (yet) so correct me if I'm wrong or there is only classic risks like falling price..

I check price @  http://bitcoincharts.com/markets/currency/USD.html

Thanks in advance for your time.
