Yes, I'm aware I won't get the 50 btc from coinbase instantly(takes about a week I believe) but I already have 50 btc in hand ready to start the process. I'd sell 50 on Gox and buy 50 more from coinbase to lock in the gains, if all goes well get my $$$ via my Japanese friend by the time I receive my 50 btc from coinbase and then repeat the process every week.
