BTC can still go to 20k before you know it. There is a resistance level at 18500, but it's not a special one. Obviously I would expect some real resistance at 20k. The behaviour of BTC at this level indicates that the bulls are not done yet, because the bears had an opening to keep BTC under 17500 but they couldn't, the bears seem to be weak at these levels. The low leverage permabears are also about to get rekt, that may be the reason. There are still a lot of low leverage cme gap bears for example that opened a short around 10k.

4 h is looking bullish massive candles in favor of the bulls.
