Nothing unexpected for me until this point (nicely done calculation though). I had long ago some experience with PoS coins and their price went lower to even lower until some even got delisted for low volumes.
Ethereum has all the shit tokens on it (ok, not all, but most). I expect those may also fall (if nothing else, at least the panic).

And my question/dilemma is... how will Bitcoin handle this, at least on short term? I'd expect another leg down, like when various DeFi "businesses" crashed, especially as the bear market is not over yet.
But how low will that go? Or am I wrong?
