An 600 million $ marketcap increase for sure does not mean that there were 600 $ dollar invested in bitcoin .... marketcap = total number of coins * current market price ... an increase in the marketcap is not an indicator of how much new money is invested. (You could say that there is new money, but for sure you could not tell that it is 600 millon $.)
Most in here know that, and you seem to be new in here (from your post count) ... i realy can't understand that noone is explaining that to you, instead they are cheering your numbers, what the hack is wrong with you guys? noone? realy?
Others already pointed out the original assumption was mistaken. Moreover, you can't even "say that there is new money" with certainty, as the USD/BTC price can rise when existing Bitcoin holders trade the same or smaller amounts (denominated in USD) of BTC with one another at increasingly higher USD/BTC prices, with no addition of new money.
