One doesn't need Mt Gox to sell $1M in btc. One just needs to find a buyer. Meet in person to exchange, or wire money to escrow. 8 years to sell through Mt Gox? Let's use our imagination just a wee bit.
And I seriously doubt that Mt Gox monthly limits are what's limiting sellers right now. You don't sell in masse into price appreciation. The herd sells on the way down. Who's had time to even think about selling in the last 4 days. It's shot straight up. This said, I'd really like to see a move back to the $50 range, so I can exchange fiat for btc at a much more favorable rate.
