BitMEX was the first crypto futures exchange that we started trading on. It gave us believe that the market is inefficient and it makes sense to spend efforts on it

Bye bye legend, it was a pure and wild fun, we will never forget that times!

🤯 Andrej Karpathy's coding rules have officially broken the internet.

[BOOKMARK THIS NOW]

144,000 stars. #1 on GitHub for 28 days straight. But 99% of people still haven't heard of them.

Here's what a CLAUDE.md ACTUALLY is, and why it quietly fixed the biggest problem with AI coding:

It's a text file Claude reads before it touches your code. Standing instructions. It never forgets them.

The 4 rules that went viral:

- Think before coding. State assumptions. Ask when unsure. Never guess.
- Simplicity first. Minimum code that solves the problem. Nothing extra.
- Surgical changes. Touch only what was asked. Every line traces back to the request.
- Goal-driven. Turn vague instructions into a test that proves it works, before writing code.

The dev who built it says it took his accuracy from ~65% to ~94%.

The rules aren't the interesting part though.

The interesting part is that almost nobody knows you can do this at all.

ANTHROPIC JUST EXPOSED HOW BADLY MOST PEOPLE ARE PROMPTING CLAUDE.

Their applied AI team dropped a 24 minute workshop.

Free.

From the people who wrote the model.

Not a course creator.

Not someone who figured it out by accident.

THE TEAM THAT BUILT THE THING.

Here is what makes this uncomfortable to watch.

There are 6 elements to a properly structured Claude prompt.

Most people are using 1.

Maybe 2 if they are being generous with themselves.

That gap is the difference between Claude giving you something useful and Claude giving you something you could have Googled.

The people who watch this workshop tonight will prompt differently tomorrow morning.

The people who skip it will keep wondering why their outputs feel slightly off no matter how much they tweak the wording.

24 minutes.

Free.

From the only people on earth who know from the inside exactly how Claude thinks.

I watched it twice.

Then I built a Claude Skill that applies all 6 elements automatically so you never have to think about prompt structure again.

Every prompt you run goes through the framework without you doing anything manually.

Full guide and the skill setup is below.

Bookmark this.

Come back to it this weekend.

This is the thing that compounds.

Follow @cyrilXBT for the exact Claude skills, prompt architecture, and systems I use to get outputs that most people do not believe came from one person.

No doubt there will be a new bull market with new ATHs

but IMO bitcoin will go lower🔵before next bull market🔴

* Note color scale is different in this chart: drawdown (BTC price / ATH) instead of relative strength index (RSI). Easier to calculate and easier to understand.

Circle has resulted in $240M+ directly funding North Korea across multiple hacks when you had hours to act for a clear cut case.

How is that compliance for USDC?

Stop acting as if you represent permission-less values you are a centralized stablecoin issuer and publicly traded company with an admin button to freeze.

Do not forget the times US law enforcement sent you the same request as Paxos, Tether, Techteryx in relation to Lazarus Group and took 5 months longer to respond.

No law says you could not freeze and your terms of service say you can freeze.

“Internet-native financial activity” moves in minutes for incidents while the ask of a court order takes days.

Instead you freeze 16 business hot wallet for a US civil case due to TRO that had incorrect tracing.

Your blog post contradicts itself in many ways and it’s clear you a leadership problem.
