I think that the resistance at $23k is a weak resistance, its not that strong, as compared to the resistance at $25k. We all can see the sharp rejection after it had reached $25k. It will break those resistance soon its just a matter of time. But I'm having a feeling that bitcoin might test 21k again the upward movement is not yet confirmed totally, but I believe that the bear season will soon be over
I think retesting of $21k isn't a big deal for this season because the price is still playing around the reach as no precise direction has been confirmed for now as to that the price can drop down or up to meet the correction before riding any direction. I think IMO that the market is not ready for a major move, it is going to be within this reach for sometime.
and besides that 21,23,and 25k had already broken and still breaking these days with those crypto market is showing support for bitcoin and with that I am sure that its soon that we will take down that 30k again.
I may not sure how short to come but what I believe is that this will come soon.
