I already invested enough in gold. 300k are alright,wouldn't exactly hurt much if I lost them but I'm not looking to buy and sell, bunker the BTC for at least 1-4 years, but still where could one go about such a transaction?
It looks like coinlab.com is setting up for serious money.
They are in process of taking over the mtgox USA customers, but, trade will still happen on mtgox.
Don't know where they are in the process.
