Bitcoin still trending between $690 - 640 and bears unable to bring it down under $640 by Wednesday will mean a pump to retest $690 will happen pretty soon.
I find last night retrace from the big dump to $640 bullish however, chances to get to $620 are slimming down here (so please consider this if you are still in fiat).
I will update my twitter and the status here once i get a confirmation of a rally
