Predictions for Thursday Feb/13 at 19:00--19:59 UTC (not earlier, not later):
Huobi: 3970 plus or minus 30 CNY (3940 -- 4000)
Bitstamp: 650 plus or minus 10 USD (640 -- 660)
I used the Chinese Slumber Method described in my previous posts, extrapolating linearly from the two Slumber Points of Feb/10 and feb/12. (The feb/11 point seems to be unreliable as discussed before.)
For the Bitstamp prediction, I assumed a currency conversion factor of 6.12 -- which was valid at Slumber Times up to feb/06, and appears to be valid again since feb/10.
