Lately, I’ve been seeing people toss around “Sell in May” . But has anyone really looked at the numbers? BTC averaged +7.4% in May across 2013–2024, but the median return? Only ~1%. Three of the last four years were red. Now in 2025, ETF flows are split (IBIT +$2.4B, ARK/FBTC outflows), macro’s shaky (GDP -0.3%, unemployment ticking up), and yet BTC still rides a “Greed” wave
So… are we acting on data or just reflexes?
Are these moves about the market, or about what we think others will do?
Feels like most traders today are front-running narratives, not price
The Sell in May narrative gets thrown around like gospel, but the data tells a messier story. Bitcoin’s May returns from 2013–2024 show a +7.4% average, which sounds nice, but the median’s a measly ~1%. That gap screams volatility big wins (like 2017 +64%) skew the average, while three of the last four Mays (2021–2024) bled red, some as deep as -35%. So, history’s not exactly shouting dump it. Yet, traders still lean into the adage, maybe because it’s a catchy reflex or they’re betting on others following the herd.
In 2025, the picture’s no clearer. ETF flows are a tug of war:
BlackRock’s IBIT pulled in $2.4B recently, but ARK’s ARKB and Fidelitys FBTC are seeing outflows, signaling mixed conviction.
Macro wobbly GDP’s down 0.3%, unemployments creeping up yet Bitcoin’s surfing a “Greed” wave per sentiment indices. This feels less about fundamentals and more about narrative chasing. Traders aren’t pricing BTC; they’re front running what they think others will do, amplified by social media echo chambers.
Are we acting on data? Nah. It’s game theory dressed as analysis moves based on vibes, not numbers. The market’s a psychological casino, and right now, it’s betting on momentum over math.
