If we are repeating the same fractal pattern of the global highs of 64k to 30k with the local high at 52k down to 40k, the 0.5 fib support of 30k to 52k (40k), transferred over to this rally would make the 0.5 fib retracement of 40k to 49k, ~44k-45k.
Just speculation, but could be more plausible as bearish div.s form on higher time frams over the 2 hour and more bids get presented at 45k.
