1 is a confluence of the 38.2% , previous support from the August 22nd low, previous resistance from the early August consolidation, and the 100 period . Psychologically important $3500 lies in this zone too. The has entered oversold territory, but there needs to be a cross back out of it for confirmation of a bottom.
2 is a confluence of the 50% , previous resistance from early June and late July, and the 200 period should converge near this area if price continues to fall. Psychologically important $3000 lies in this zone too.
I'll await confirmation signals before basing any trades off of this, but it is highly likely to see a good bounce if not full reversal in both of these areas should the price make its way down that far. It's hard to predict if China or elsewhere will cause more FUD at this point. It does appear that most of the impact from this has run its course though. Unlike previous major sell offs, a large number of alt coins are still doing fairly well, and there isn't the mass flight of liquidity out of all crypto's that we saw before.
