As promised, Mt. Gox has reenabled cash withdrawals after taking its system offline to iron out the kinks. The Bitcoin exchange says it's successfully processed over $1,000,000 worth of transactions during these past two weeks of testing, which has given it the confidence to resume business -- despite a backlog on some transactions. Mt. Gox is also announcing that it's signed more banking partnerships "in Japan and around the world," though no specific companies were named. If you want to get into this whole Bitcoin thing, but don't know where to start, we got you covered.
