Why Most Crypto Price Predictions Don't Beat a Coin Flip

"Bitcoin will hit X by Friday" is the most common kind of crypto forecast — and the least tested. We took a typical technical model (an EMA20 trend projection) and ran it on every day of 2025.

The result

• Direction called correctly: 51% of days for BTC, 53% for gold — statistically indistinguishable from a coin flip.
• Its price error was slightly worse than simply assuming the price wouldn't change.
• A strategy trading its signals lost money after fees.

Why a small error can mislead

A forecast that misses by 1% sounds accurate. But Bitcoin often moves only 1–2% in a day, so "no change" achieves about the same error. Any honest forecast should be compared to that naive baseline, not presented on its own.

What can be forecast

Volatility clusters: calm days follow calm days and wild days follow wild ones. That makes the size of the move far more predictable than its direction. A calibrated range — "the close lands here 8 days out of 10" — can be checked every day, and ours is: see the full record.
