We are at 2.272 Fib extension from last bigger jump from 2980 USD. If we will break this one, we can get to 2.618 (6470 USD) and higher.
If we won't break it, there are chances to retrace back to (most probable ones):
a) 0.382 Fib retracement mark (4970 USD) - this is also previous significant high.
b) 0.5 Fib retracement mark (4590 USD). This one also corresponds to 30 day cycle in current trading channel on (day 0 at first channel low, day 30 at first channel high, day 60 at second channel low, day 90 at second channel high).
But this is just pure TA and we may be completely wrong and BTC will just go higher. "Keep watching it" is probably the best advice right now ;)
