This Bullshit aint the work of an aggregate market.
This is just a few players with the power to defy all time learned principles of market mechanics, in order to deprive the maximum of unsuspecting punters of their USD and Bitcoins, but mostly USD.
This market is fucked.
well of course that bitcoin is very very unpredictable and not stable, maybe you're new bitcoin used and don't know but price of bitcoin can change by 50$ in one day, and nobody can predict that, so of course that bitcoin is unpredictable
