What to demand

Proof over promises

A real mentor lets you study the call they made; a guru asks you to trust the call they describe.

A screenshot proves only that an image exists. It says nothing reliable about when a call was made, or whether the entry and grade were nudged after the trade went the wrong way. For a student that ambiguity is fatal, because you cannot learn from a decision you cannot trust was real.

A cryptographic timestamp removes it. The mentor this guide points to reduces each call to a SHA-256 digest built from the call's entry price, its target, its stop, the conviction grade and the clock time it went out, then anchors that digest into a Bitcoin block through OpenTimestamps the instant the call goes out. A hash is a one-way fingerprint: alter any field afterward — entry, target, stop or grade — and the digest changes entirely and stops matching the public receipt. So a confirmed receipt proves the exact call existed in that exact form before the trade resolved. Because the grade rides inside what gets hashed, a mentor cannot quietly bump a C up to an A once it wins and then teach the win as though they saw it coming.

How a graded, time-stamped call becomes a repeatable lessonFlow diagram: a mentor publishes a call with its conviction grade and timestamps it to Bitcoin; the student studies the documented decision while the trade is still live; the result is later checked against the locked grade and entry; and because nothing can be edited after the fact, the same lesson can be re-run by anyone, long after the trade closed.DECISION TIME → (the lesson is fixed before the result)Because the grade was locked first, the student learns from the decision, not the hindsight.1 CALLgraded A-D andBitcoin-stampedat the decision2 STUDYthe reasoning,before theresult is known3 CHECKoutcome vs thelocked gradeand entry4 RE-RUNanyone repeatsthe lesson fromthe public record
Real mentorship teaches the call as it was made. Freezing the graded call on a public ledger is what keeps the lesson honest after the outcome is known.

Walk one lesson through it

Picture an illustrative call (a made-up example for the walkthrough, not a specific real trade): long a liquid index ETF, entry 412.80, target 414.20, stop 412.10, grade B, time 14:32:05 UTC. At publication the mentor runs those exact fields through SHA-256 and pins the digest to Bitcoin. The trade resolves later that session. Weeks afterward, a student can take the published call, recompute the digest from those same five fields, and confirm it matches the receipt recorded against a block mined before the trade closed. Had the grade been nudged from B to A after the fact, the digest would fall out of step with the receipt — and you would know the lesson had been edited.

The point is not the numbers; it is the order of events. The receipt is dated by the Bitcoin block, and that date sits before the outcome. That is what makes the call a lesson you can learn from rather than a story you have to believe.

Where the field falls short

What failing this test looks like

Most mentors fail this test not through fraud but through format: where their calls live, nobody can pin down when they were made or what grade they carried at the time.

  • The social-media guru. The whole brand is a personality, and the personality controls the timeline. A losing call can be deleted, a winning one can be amplified weeks later, and the “record” is whatever the feed currently shows. It fails a verified record and usually aligned incentives too, since the money often comes from affiliate links rather than the teaching.
  • The course-and-community operator. The curriculum may be genuinely structured, which is why this archetype can clear a documented method and open pricing — but the founder's own live trades are rarely time-stamped or graded, so you learn a framework without ever seeing the teacher trade it under real conditions. It fails a verified record and decisions over results.
  • The signals-room caller. You get calls, but seldom the reasoning and almost never a grade fixed before the outcome. It is instruction without a syllabus: a stream of tips you cannot study, audit or learn a repeatable process from. It fails decisions over results and a verified record even when the room charges a clear monthly fee.
  • The prop-firm affiliate. The teaching is a funnel toward a paid evaluation or a particular broker, so the lesson bends toward whatever pays the referral. The incentive is the sign-up, not the student's progress, so it fails aligned incentives outright — and usually the verified record with it.

This is why the guide ranks a field of mentor types rather than reviewing one course: calls proven and graded before the outcome is precisely the test most of the field cannot clear, which is what makes clearing it the thing worth paying to learn from.

This is the one mechanism that turns a mentor's history from something you take on trust into something you can pull apart and test, which is why it sits near the top of the scorecard.
