wtf... Block reward is 6.25BTC and i saw a block that almost got 2BTC just from fees...
I've seen fees around the same level as the total block reward when it was double that amount. It all depends on how many people are willing to pay.
Can anyone explain what's going on? Whats that high insanely demand on the Bitcoin Network??
