Can someone tell me what triggered this sell off? I know people were speculating that there was some manipulation to keep prices constant.
I witnessed a series of very large sell offs getting slammed into Bid wall on Stamp. Individual sell orders so large, that the whale executing them must have either been panicking, or deliberately trying to smash the market.
Included amongst them, was a single sell order in the region of 1700 BTC, that took Bitstamp down from $705 - $666.6666.
Seems like you need larger and larger amount of bitcoins and money to swing the prices.
