Comparison of what happened to the violent downward movement in price we saw over the weekend for Bitcoins and all Alt-crypto currencies.

People in the finance industrial well know, that HFT supercomputers can manipulate price with flooding buy/sell orders in split seconds. Maybe, the banks and governments have already adapted the technology to Bitcoin and Crypto coin exchanges.  If they want to scare people out of crypto coins , fear is probably the best motivator.

Hmmmmmm...............
