What's the big deal? Miners create 200,000 BTC every 55 days.
Your point being? What does that statement have to do with the topic?
Considering the fact that miners conjure up bitstamps entire bidbook every 5 days and this hasn't crashed the price. The 200k gox coins are irrelevant.
Second off, nobody will market dump 200k on Bitstamp. Why? Because bitstamp will never pay you out. Owners are already in flashy cars, while hitting withdrawals with AML/KYC excuses.
Third off, this assumes no side fiat enters to provide bids. 200k coins is like what 48hrs of volume on some days? That is nothing.
Fourth, this assumes Mt.Gox even had 200k BTC. Mt.Gox is posting theoretical balances from when bitcoin was worth a few penny's. Seriously the realistic victim losses are closer to $10-15million USD, nowhere near $100-500mil. Mt.Gox order books had what, 40k btc on them back in Spring 2013? By the end of the year it was closer to 20k btc. Are you really going to believe 180k BTC were idling around an exchange that has had warning signs for 8months prior?
Bitcoin has also never had more then 50mil on all exchanges combined in available fiat bids, and that is being generous. Bitstamp is lucky to see over $10mil of active bids.
Mt.Gox is old news.
