Our upside scenario is mostly worked out as BTC has hit predefined 37-38K target but unfortunately missed swing to 28.25K before the rally. Sometimes this happens. But it doesn't mean that 28.25K level should be ignored.
As a result of Friday's jump, we've got bearish grabber on daily chart, that particular suggests drop below recent lows and reaching of this target as well. This scenario is short-term, mostly tactical. It tells that until price stands below recent 38K top - it keeps chances to reach 28.25 level. So we definitely know the target and invalidation point.
For position taking we could consider two Fib levels inside the grabber's range. The simplest way to act is to split position and enter gradually, to minimize possible loss. Second - avoid any strong upward action, don't be short in this case. We need gradual and slow retracement.
