People at the end of the year spend money a lot, also at the end of the November when the thanksgiving is and after that the blackfriday so the price until then and after it I think that will not go below $350-$400, but one thing is for sure that $100 is way to far from the current price.
yeah and I think that we will not see price below $500 in future, $500 will be the maximum bottom and $100 is simply impossible now.
Checking the last few weeks trend we can see that bitcoin price pretty much the same as 1 month ago even through the recent days the graph shows that price is going down slightly.
The trend of new coins in the market it slowing down so the price should not decrease if more people join and use bitcoin.
