My overall view

I wouldn't call for a guaranteed 30% crash yet. The market currently has real bullish momentum, strong ETH relative strength and renewed BTC ETF inflows.

But the risk/reward is becoming increasingly asymmetric for late buyers after such a rapid rally. BTC's extreme RSI is a legitimate warning, although not a standalone sell signal.

MarketWatch
So I would frame your thesis as:
“The market doesn't need a fundamental disaster to fall 30%. It only needs the current momentum to fail, support to break, leverage to unwind, and FOMO to turn into fear.
And if BTC breaks $70K–$72K, that's the level where I would start taking your $55K BTC / ~$1,735 ETH / deeper altcoin correction scenario much more seriously.
