Right now i´m feeling low because of this bearish sentiment that seems to have invaded the cryptocurrency market. In Poloniex all except two coins (Peercoin and Namecoin) are red, but no a simple red a deep red, falling with no support and non stop, the bigest one has a change of -23%. I don´t know the reason, if there is any specific one, i prefer to think that is part of a normal and cyclic behaviour of the market, so there is nothing to do but wait a rise, that those coin take a breath, and their plans and project turn into a positive dirección.
Cycling behavior of the market + massives ICO being cashed out = rollercoaster time.
Just look at the BTC/USD or EUR value history, doing down then months later, new "all time high". It's not anormal.
But there is still a chance that this time is different, we will never know.
You are right, there are several factors that push down or pull up the prices, i would to add at this moment the high probability of a bitcoin hardfork.
