you do realize that bulls have been sprinting for like 3 weeks don't you !? it is very normal for the market to rest and correct even to mid 8k.
The support we are having is a positive thing, but any negative news could impact the market and the price will go down, since the price rally is merely a speculation, anything can happen when there is a negative news.
as for the 6K i do not see a Technical-reason for that to happen. we have built some nice support areas above 7K and it won't be easy going to 6K again.
Right now there is nothing to suggest that the price will go down, MtGox team is waiting to liquidate their bitcoin when the price rises, so anything is possible.
as for the 12K point , you are 100% right. most people are waiting for that break, that's why i said when we break 12K then 20K will come in no time.
anyway let us wait and see what's up! . my SL is at 8400$
Once the price crosses $10k we might see the price moving to $15k until there is a massive sell off, as mentioned earlier i am sure MtGox team will liquidate their coins when the price reaches their target and putting a stop loss in this market is a bit foolish unless you are holding the coin at a massive profit.
