With price falling sharply bitcoin price has reached a trendline which goes back a long way on log scale. For bullish scenario you want to see rebound off that line from hereabouts. Be wary of conceeding support as broken too soon though, small spike below that line would not be surprise. A run back up to top the channel could be on the cards.
If line fails to hold support, next support below that is the area where the previous bitcoin bubble finally peaked however bullish path marked by last green arrow would not be expected if price falls down there.
