Bitcoin- New leg up is probable

In my previous Bitcoin analysis I said that although I'm quite bearish in the medium term, a leg up can happen on Bitcoin.
Indeed, we had this first leg of correction with BtcUsd rising from 45.500 to 49.500.
Now Bitcoin is in a slight correction of this first leg up and is dropping slowly putting in a flag pattern on our short-term chart.
A new leg up is pretty probable at this moment and my target for this correction can be reached (52-53k zone).
As I said multiple times, only and only Btc above 53 would change my medium-term perspective to bullish.
