BTC looks like it is completing the final correction wave and, in the worst case scenario, it will hit the ~10k support line. Do note that the support line in the area where it will hit is very close to the .382 Fibonacci retracement line.
In the worst case scenario the BTC price might hit below €8k, before turning up to reach new ATH. :-) I'd expect the RSI on the daily chart to drop below 30 ...in the worst case scenario. But before this happens, the price might as well bounce from the ~€10k support level, as you expect, before continuing further down.
