Directly no. Indirectly through its psychological effect on those mining coins yes.
I don't get how the price is going down after a difficulty increase... anyone able to englighten me (and others)?
The price of bitcoins is not determined by the difficulty of mining them.
This argument comes up so many times on this forum.
Imagine if the difficulty rose tomorrow to 10,000,000,000,000,000,000.
Do you think miners will want to sell you any coins for today's low low prices?
Or do you think they'll hold out for higher prices since the prospect of them mining more tomorrow is now diminished?
