When do you think the correction will happen?
It's weekend and usually people tend to take their profits at the weekends.
People take profits when it hits round numbers. So $4000 is the target, and only after that is hit will it pull back. It's true that sometimes there are dips on the weekend, but that is due to the difficulty in moving fiat to the exchanges on the weekends.
(I initially thought the Bitfinex thing would hold back the price, but the market is ignoring it for now).
