BTC has no volume to speak of. It´s really microscopic.
On a very good 24 hr.period it trades like 1/60th of what for example Facebook stock turns over in a 6.5 hr. session. On the average it´s more like 1/100th.
Compared to FOREX that turns over 5 Trillion dollars in a day, BTC volume is just pocket lint.
P.S. Last 24 hrs. volume 20,617,800 = 1/150th of Facebook stock turnover in a session. Pocket change.
