3.6 million dollars per day works out to ~110 million per month. By contrast, QE is creating 83,000 million dollars per month.
For the record, I don't see what the mining rate has to do with flows in and out of the exchanges.
Sorry, what is QE?
Is my math right with 110 million dollars per month - that worldwide, (assuming in this example that 1bc=1000 dollars) every month bitcoins have to be bought at 110 million dollars? Seems a cracy lot.
25 bitcoins are mined every 10 minutes, and these bitcoins are sold at some point. So to hold the price stable on average 25 bitcoins have to be sold every 10 minutes with new fiat money. (?)
QE is Quantitative Easing. A strange term, but basically it means inflation. The Federal Reserve is "easing" tightness in the economy by increasing the quantity of money, with the fig leaf of buying bonds. This inflates the money supply, props up the bond market, and enables about a trillion dollars a year of federal spending.
Your math is right, but your assumptions almost certainly are not. 3600 new bitcoins mined per day does not in any way suggest that 3600 bitcoins are sold (for new cash) in that day.
