Seems like we're meeting a bit of resistance at 4.8k - 4.9k
Seems to me like the 5k wall is being sold off in smaller chunks, it used to be 17 BTC if you remember
now we have had 2 small "dumps" which happened now and approx. 7 hours ago and 5k only has a "wall" of about 3 BTC, just a wild guess though
