Down another 20%.
Smart money, or investors realising that its a ponzi scheme.
Even tax avoiders and criminals would have been better off paying tax.

Problems recently with hacking into a major exchange and a major bitcoin "miner" pulling out because of the low price.

VERY hard to trade these days for a punter with these swings. My nice profits cashed in but lost again in 10 minutes having a coffee break....
I would expect to see further declines, all IMO.
