I personally still don't think the previous price increase was as a result of the imposed war. It could be normal market activities or some investors are using this means to signal more buy.
I agree though we don't know real circumstances behind. But the most obvious part is that the major exchange happens may be triggers other people to join the possible hype not knowing that it is just one of the many factors. However we couldn't blame them, could we? Still they drives the market at some spot though.
We can blaim them anyway such people must exist in the market for other people to make profit from there trading.
