A medium-of-exchange that isn't private by default would never work in today's regime.
If you treat privacy as "expert mode", you guarantee surveillance wins by default.
You need privacy & fungibility by construction, not by habit.
If surveillance can reliably distinguish "good" vs "bad" coins, policy and perimeter will always drift to "good only".
All transactions must look like each other:
- No transparent subset as "legacy mode".
- No visible amounts or script opcodes per tx.
- No address types that reveal more metadata.
This collapses the main control trick: "we only KYC or de-bank these flows".
Make the policy choice binary: ban the entire asset, or accept that everything is indistinguishable.
This way you have no taint wars, no heuristic creeping.
Privacy-by-default vs opt-in privacy is basically the difference between:
- You're dark unless you explicitly shine a light.
- You're lit up by default unless you personally crawl around the interface turning lamps off.
You don't get tax exemptions by begging corrupt politicians, you get tax exemptions by implementing privacy by default.
Privacy by default protects the lazy, the busy, and the non-expert.
Opt-in privacy protects only the most disciplined, and even then often only cosmetically - while turning them into a distinct, more interesting group.
Bitcoin will fail as mass, non-custodial Medium-of-Exchange
When we look at the past 5-10 years, Bitcoin’s trajectory is quite clear. Capture goes up, freedom goes down.
In July 2025, the BIS published their "Quantum-readiness for financial system: a roadmap paper".
The first few sentences of the Abstract are quite clear: "Quantum computers may in the future break today's widely used encryption. This paper provides a framework to support the financial system in the transition to quantum-safe cryptographic infrastructures. It emphasises the need to start the transition today – with broad awareness and cryptographic inventory as critical foundations".
Then in December, the BIS published their "Project Leap phase 2: quantum-proofing payment systems" paper.
"Protecting financial systems from the potential threat posed by quantum computers requires a proactive and coordinated approach. Challenges go beyond technical aspects and include awareness, resource allocation, competence development, inventory, pilots, governance and more.
Project Leap Phase 2, a collaboration between the BIS Innovation Hub Eurosystem Centre, the Bank of Italy, the Bank of France, Deutsche Bundesbank, Nexi-Colt, and Swift, tested post-quantum cryptography in an operational payment system.
The experiment replaced traditional digital signatures with post-quantum cryptography, while sending liquidity transfers. It involved modifying numerous system components to ensure compatibility with updated cryptographic libraries.
"
In June 2025, the EU published their "A Coordinated Implementation Roadmap for the Transition to Post-Quantum Cryptography" paper.
"
The EU Member States, supported by the Commission, issued a roadmap and timeline to start using a more complex form of cybersecurity, the so-called post-quantum cryptography (PQC).
Quantum computing has been identified as a threat to many cryptographic algorithms used to protect the confidentiality and authenticity of data. This threat can be countered by a timely, comprehensive and coordinated transition to Post-Quantum Cryptography (PCQ).
This document is the first deliverable and is meant to be a first high-level paper aimed at Member States. It includes a set of recommendations that Member States need to implement for a synchronised transition to PQC, as well as measures to ensure that all stakeholders are well informed on the quantum threat to cryptography.
"
These are just 3 recently-published papers of many. They are written as if Quantum Computing being able to scale cheaply and reliably enough to be broadly useful is a foregone conclusion.
The coordination between ALL countries is insane. If you want to be a part of the new financial system, you'll have to play game.
As I've shown in this article ( 
It would've been kinda weird if Central Banks just started buying 3x the gold year over year without an excuse 😂
And this is just official Central Bank gold buying, the real numbers are in the multiples.
I think they are preparing for a financial reset and I wouldn't be too shocked if they decide to run it this or next year.
Central Banks usually under-inject liquidity in midterm years.
With current consent levels, they won't be able to sell the majority of the population on CBDCs and they are well aware.
The Controllers (BIS in this case) didn't force 137 countries (= 98% of global GDP) to develop CBDCs so they can beg the population to switch to CBDCs/Digital ID. They know they'll have to use a crisis.
We'll see a systemic collateral/custody rug and people will get forcibly converted into CBDCs to "save the financial system".
David Rogers Webb (author of the Great Taking) went to the US to try to change the law, but unfortunately they were unsuccessful.
Great Taking = legal + plumbing architecture that lets the top of the collateral pyramid seize or haircut claims on financial assets in a systemic crisis, while keeping the underlying assets safely inside the system.
Translation: you don't own any of your stocks/bonds in your brokerage account.
David Webb filmed his attempts to change the law in a few US states and got threats from the banking lobby.
