BTC UP — a crypto call we sealed on Bitcoin

We had a hunch and wrote it down while everyone was too busy celebrating to notice. Before the day it's supposed to land, we bit it onto Bitcoin's clock — a timestamp nobody can fake or quietly delete — so anyone can check exactly when we called it; you decide what it means.

Missed — kept honest

The call we recorded

The meme reads either way — here's the precise bet sealed underneath. We prove WHEN. You decide WHAT.

BTC ↑ UP -2.5%

within 14 days · stated 55% odds · LOW

sealed 21 Jul 2026 event 4 Aug 2026 · we called it 14d early

Missed — kept honest

How we grade this: a hit needs BTC to close higher on 4 Aug 2026 than on 21 Jul 2026. BTC moved -2.5% over the window → miss. It's just public BTC price between the two dates — graded automatically, no judgement call from us.

The story

On 21 Jul 2026, CoinBra.in recorded a BTC up call (resolving within 14 days), wrapped in a deniable euphoria meme you can read either way. The exact image was SHA-256 hashed and timestamped onto Bitcoin block #959,031 BEFORE the candle printed — so the timing cannot be faked or backdated. It resolved against us: BTC moved -2.5% over the 14 days window, so it is logged as a miss and kept on the record. 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.
