If you are at all bullish Bitcoin in general, then this market has done all it should need to to tempt you in @ $90, which represented a re-test of longer term rising support and 'fair value' within this context.
Does this mean that the sell-off is over? Well, as ever we can never know, but what we can say with confidence is that technical reasons for bulls to overpower bears accumulate quickly below $90, which is why we have already seen a bounce.
