I'll also add that price action has been doing things lately like I haven't see much before. On a wisdom 15 min chart it is apparent that something is trying like hell to keep price up. There is a bizarre amount of flat price action with the occasional heavy sell, only to have it bought up and held at the previous level. Very little buying is occurring currently. We are nearing the first auction of the US Marshal's 30k btc , only days away on June 27th. It would seem that market makers are busy. A 100% retracement to $450 would not be surprising. Watch for a break of the neckline.
