Three days ago, I wrote "Caution, October us upon us" and mentioned Bitcoin strong resistance between 4400 and 4500. Should you have shorted, or are standing by - now that the price has sold of to the 4200 area, a stop loss should go in at the recent high: or the 4460 area. If the price drops another $50 (4150), the stop would go to just over 4400. thus esablishing a low risk / break even trade with potentially significant downside potential.
