according to mt gox it only takes one market dump of 87,000 btc to take price back down to $50 yip yip
Is this amount based on real life evidence or just speculation?
Actually i think that is fairly inevitable since bitcoin is far too overvalued currently.
A drop to more sane levels and trending steadily upwards afterwards via organic growth instead of speculation would be a lot healthier imho.
Overvalued in what way? It's only value is in what people are prepared to pay, Sounds like you just want to catch a cheap ride on the bitcoin train back up.
