Just literary a minute after my post the price got pushed up from 8125 to 8200 with some very big buy orders at Bitfinex, other exchanges did not really follow and drop a bit again. But at the moment i can see another attempt happening. Coinbase is the weakest link at the moment with a difference of 30 points, it has been the weakest for a weak now.
Now the problem with this is, if the price difference gets to big, there are automatic trading bots who try to profit from these price differences (arbitrage), so even though Bitfinex is trying to push the prices up, these bots will probably automatically push the price down at Bitfinex as well, because they can earn some points while doing so.
I can still see the same 100 btc buy orders just waiting to get filled from the 8160/80 all the way down to the 8120 again just now. Or it's someone who is over confident :) or something is going on here
