Why? The 50k were always the target for a correction.
What you like many Bitcoiners didn't understand even after we Monero Bros were screaming it from the roof tops is: fractional reserves are back, loaning out ones BTC for fiat is back.
Price since 2017 is underperforming because fractional reserve ratios ate constantly increasing.
125k top vs 400k top (conservative projection) represents a 33% backing of funds which is more than enough.
From Monero we learned that only below 10% often below 5% withdrawal problems start to arise. Next top will be muted even more. I'd guess 180k at a fractional reserve ratio of 10% which would represent a fully realised price of almost 2M peak.
CME, CBOE and now ETFs are a deal with the devil. It will hinder price discovery for years to come.
