BTC UP — a crypto call we sealed on Bitcoin

Everyone's grinning like the party will never end, so we wrote down a hunch while the confetti was still in the air. We stamped this on Bitcoin before the 14 days played out — a Proof-of-When (proof of exactly when we said it, not that we're right) — so check the date, decide the rest yourself.

The call we recorded

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

Open call

How we grade this: a hit needs BTC to close higher on 18 Aug 2026 than on 4 Aug 2026. It hasn't resolved yet — grading happens automatically on 18 Aug 2026. It's just public BTC price between the two dates — graded automatically, no judgement call from us.

The story

On 4 Aug 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 #961,039 BEFORE the candle printed — so the timing cannot be faked or backdated. The call is still open; it resolves 18 Aug 2026. 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.
