That's a huge percentage increase on the volume although the chart might be not as accurate as your seeing it now but still the real output is close to this and the late good events taking place could be the reason behind it
Any chance this points to some massive change of ownership that nobody is talking about or discovered? Satoshi coins moving???
I doubt that there's a chance for satoshi wanting to move the coins or rather change the ownership buy again if nobody's talking about it or no one haven't discover it then there's no way to know for us
