Expect to see more trade volumes around $90 or $80. These are psychological numbers. $90 and $80 will become both support price level and resistance level, depends on how long the exchange rate stays above or below these round numbers. The longer exchange rate stays below $100, the more likely we will hang around $90.
Unless we are in for a long slide, with prices dropping week after week. If so, support after support might be gobbled up over time. The good thing about such a scenario, is that we will find the real support. How far down does it have to go before miners think "frack this, i'm waiting for BTC to rise."
