It is essential to remember that there is massive inflation of the money supply going on (by design), and that this is the key driver of the price downwards. ~35% increase in the money supply over the next 12 months; proportionately higher over the last 12 (as the same in absolute terms). Its rise to $30 was driven by hype and speculation. The falling prices stop any speculators jumping on board, and there is no sign…
The value is mostly driven by mass psychology, the inflation caused by miners is only one factor.
If some goverment-issued currency would start hyperinflating, bitcoin or similar cryptocurrency would be pretty good choice for people to move to.
