Do we have any proof what stand behind recent price rise to $600+? And I don't expect any price shift.
US banks are closed for the Labor Holiday today so if price will shift dramatically then Chinese traders are behind this.
I see you have doubts about China's ability to affect the btc price.
Rest assured they (People's Republic of China) have the most number of Bitcoins, they have the most number of bitcoin miners, they have the most number of bitcoin traders, they have the most number of everything related to bitcoins, Do you understand now?
Chinese started buying up right after the Chinese Communist Government announced a new round of yuan devaluation. Which drove up the price of btc immediately to 600+ territory. If you have any googlefu, you can verify yourself, no need to ask others for proof.
It doesn't matter US banks are closed today. What matters is if Chinese continue to buy, if they decide to sell or if they decide to do nothing. Really. The fate of btc is in the hands of the Chinese, not America.
