A B-wave reaching a 2x extension, is on higher tf probably previously unseen in BTC. And, I would expect that that continues to be the case.
Yes, if its indeed a B-wave, at 2.236 extension, it would probably be the largest Bitcoin has done, on a higher timeframe.
Most recent B-wave was from Dec 2023 to Jan 2024, and was almost 2.00 extension, albeit on a smaller timeframe...
