Can I deposit USD via OKpay, is that instant? If that works, you can just deposit funds to mtgox. and buy mtgoxcoin. current spead is $625(bitstamp)--$252. 1 real btc=2.5 goxbtc. why people still want to give 70% to buy mtgoxcoin? That make no sense to me. But hi, everyone has different investment stradgies.
This works, I sold btc on btc-e, cashed out to OKPAY and then made a deposit to mtgox. Neither cashout at btc-e nor deposit at mtgox is instant so it could take anywhere from a few hours to several days. I did a test withdraw with 1k and had the money in exactly 24 hours. Currently waiting for 20k deposit, been waiting all day. Fingers crossed, there are some risk doing this, you don't know where the price is going in the meantime, and if you're unlucky it can take days. This hassle and risk may justify an extra 20-30% for some, I would argue that there is some risk receiving goxBTC as well since it's technically possible for those to be charged back by mtgox at later stage.
I certainly prefer the btc-e -> okpay -> mtgox route, but I don't dare do any large transfers since I may end up getting stuck.
