HFA / 2021

How the work gets done

Four rules that have not changed since 2021.

They are also the reason some people leave. That is the trade.

Show the mechanism

A number without a mechanism is a rumour. Every strategy gets explained down to where the yield actually comes from.

Name the invalidation

Every thesis ships with the condition that would kill it. If that condition arrives, the thesis gets retired in public.

No ads, no sponsors, no referral links

No YouTube ads, no paid promotions, no channel sponsorships, no exchange referral codes. Analysts disclose what they hold.

Post the losses too

The post-mortems are on the public channel with everything else. A record that only contains wins is not a record.

No borrowed certainty

Watch the process, not a highlight reel

Taiki’s public archive includes strong views, changed views, and losses. He has published a thesis invalidation, disclosed a six-figure loss on X, and recorded an hour-long post-mortem of a trade he got badly wrong.

That is the point. The value is not pretending the uncertainty went away. It is watching a serious investor say what failed, update the thesis, and revisit the risk in front of the people paying him.

From the public record

Rotated some BTC to ZEC. ZEC is now my biggest bag. My STRC/BTC thesis partially invalidated due to Saylor mismanaging it in my eyes.

A thesis revised in public, 2 June 2026. Still in play. Read the post on X

Independent research. Since 2021.

Bring a thesis. Leave with a sharper one.

If you want guaranteed calls, this is not your room. If you want research that shows its assumptions, a founder willing to update the view in public, and peers who can find the hole in your argument, come and have a look.
