Been looking at Bitcoin's risk-adjusted returns lately and honestly the numbers aren't looking great right now. That key Wall Street metric everyone watches - the Sharpe ratio - just turned negative for BTC, which basically means you're not getting paid enough for the volatility you're taking on. I get why people are still bullish, but when the Sharpe ratio goes negative it's a pretty clear signal that the reward-to-risk trade-off has flipped. Not saying don't hold, but entering new positions when the Sharpe ratio is in the red feels like catching a falling knife to me. The metric's been a decent indicator historically, so I'm watching to see if it stabilizes or gets worse from here. Anyone else noticing this shift in the risk landscape?
