BTC SIDEWAYS — a crypto call we sealed on Bitcoin
We looked at the market and bet that today it does pretty much nothing — a whole lot of sitting perfectly still. We stamped that hunch onto Bitcoin before the day began, so anyone can check exactly when we called it; we prove the when, you decide the rest.

The call we recorded
The meme reads either way — here's the precise bet sealed underneath. We prove WHEN. You decide WHAT.
Called it
How we grade this: this is a "stays flat" call — a hit needs BTC to move less than ±2% between the two dates. BTC moved -0.3% over the window → hit. It's just public BTC price between the two dates — graded automatically, no judgement call from us.
The story
On 16 Aug 2026, CoinBra.in recorded a BTC flat/sideways call (resolving within next day), wrapped in a deniable chop meme you can read either way. The exact image was SHA-256 hashed and timestamped onto Bitcoin block #962,757 BEFORE the candle printed — so the timing cannot be faked or backdated. It resolved in our favour: BTC moved -0.3% over the next day window. This page proves WHEN the call was made — not that it was right, and we never delete the misses.

Don't trust us — check: (1) SHA-256 the PNG → matches the hash above; (2) the .ots proves that hash existed no later than the Bitcoin block (un-backdatable); (3) the outcome is just public BTC price between the two dates. Proof of when, never of being right — misses kept.
