Bitcoin just reclaimed $81K and people are asking why it's rising so fast. Honestly, it's not as bullish as the headlines make it sound. The main driver is ETF money flowing in—we've seen roughly $2.7B pour into spot ETFs over the past few weeks, which is real institutional demand. But here's the thing: the actual spot buying from regular traders? Pretty weak. Most of the rally is coming from leveraged long positions and perpetual futures, which is a classic setup for a quick reversal.

I checked the on-chain data and April's move was almost entirely driven by futures demand while spot demand actually contracted. That's the kind of divergence that usually doesn't end well. Prediction markets are pricing maybe a 56% shot at $85K this month, but only 23% for $90K—so even the market isn't convinced this is a breakout. It's more like a grind higher that could easily reverse if inflows slow down or traders start unwinding positions. Watch the ETF flows closely; that's really what's holding this up.
