I think we are in a bubble that will correct, as many do, but I also think that is an assumption. I'll call it the bubble assumption. If the price of bitcoins is going up at this rate and we think it is a bubble and it will come back down it makes the assumption that whoever is buying the bitcoins is doing so for a short term investment. Or it makes the assumption that the "correction" hasn't already happened, and yet either new investors, or the same ones simply bought their way through it. It makes the assumption that as the price rises... those who feel it is a bubble still haven't yet sold, and that money hasn't gotten into more "steady" hands.
I could go on and on but the truth is there are many possibilities and I don't think there is enough information to really know one way or another what the price of bitcoin is going to do.
I wish I was a big fish
