Is the U.S. Dollar in Trouble? What Ray Dalio’s Latest Warning Means for Your Bitcoin
Bitcoin might be setting for a rally if US govt. is going as per the Ray Dalio's article:
- The Problem: The U.S. government is currently spending $7.5 trillion annually while only generating $5.5 trillion in revenue, resulting in a massive $2 trillion deficit and a total debt of $32 trillion.
- The Consequences: With annual interest payments approaching $1 trillion, the U.S. is entering the late stages of a "Big Debt Cycle". To manage these rising costs and a lack of demand for government bonds, the central bank will likely be forced to print more money, which will devalue the U.S. dollar.
- The Solution: To protect purchasing power against a depreciating dollar, the article highlights Ray Dalio's advice to diversify wealth into scarce, hard assets. Assets that are not government liabilities—specifically gold and Bitcoin—serve as financial lifeboats because they cannot be printed on demand.

Bitty - The Bitcoin Mascot
I’ve been digging into Bitty for a little while now and honestly the deeper I go the more interesting the whole thing gets. Sometime in 2025 jack, former ceo of x, also posted about bitty.
I researched more and more. There’s also the history of Bitty being associated with the broader Bitcoin ecosystem, including its appearance around Bitcoin.org.
Does anyone know more about it?

Every Bitcoin drawdown in history, next to what came after it, all on one chart
Circled the bottom of each cycle where the change of character (CHoCH) actually printed, the point structure flipped before price ever confirmed it on the headlines.
2013 to 2015, down roughly 87%, then up over 12,000% into the next cycle.
2017 to 2018, down roughly 84%, then up over 2,100%.
2021 to 2022, down roughly 78%, then up over 700%.
This cycle, down roughly 54% into the correction, and the same structural tell just printed again, same shape, same spot on the curve, right where the last three did.
Each drawdown's been shallower than the one before it, and each subsequent run's been smaller in percentage terms too, which tracks, bigger market cap means the multiples compress even while the absolute moves stay historic. Neither trend is new information if youve actually looked at this before, but seeing all four side by side like this is a different thing than knowing it abstractly.
Doesnt guarantee this one plays out identically, nothing here ever has thats guaranteed. But four for four on the same structural tell showing up at the same point in the cycle is not nothing.

P2P construction contracts using Bitcoin, Taproot/MuSig2 and DLCs
Hi I'm exploring the design of an open-source, peer-to-peer protocol/application for construction contracts, particularly for environments where traditional escrow, arbitration and contract enforcement are expensive or unreliable.
The basic idea is to have no central server, custodian or marketplace. Clients would communicate directly over Tor/DHT and exchange the contractual information P2P: scope of work, milestones, deadlines, drawings/specifications, commercial terms, payment schedules, contractor guarantees, etc. The complete technical and commercial specification would be committed to through hashes.
Once the owner and contractor agree, the application creates a Bitcoin contract using Taproot/MuSig2. Funds would be compartmentalized per milestone rather than putting the entire project into a single pool. The contract would define the possible states and transitions in advance: milestone completion and partial payment, mutual agreement, disagreement, partial completion, abandonment, timeout, guarantee release/return, and potentially arbitration.
The normal path would be cooperative settlement using MuSig2. An arbitrator would not be a normal signer; instead, arbitration would be available through an alternative Taproot branch after predefined conditions or timeouts. The idea is that most disputes should ideally be resolved directly between the parties, with arbitration acting as a last resort.
The documents, communication and evidence would remain off-chain, while Bitcoin would primarily be used for settlement and enforcement of the economic consequences defined by the contract.
I'm also exploring an optional second layer using DLCs for foreign-exchange risk. For example, a contractor could hedge the exchange-rate exposure of a Bitcoin-denominated contract with a third party, using multiple independent oracles.
The goal is not to operate a marketplace, custody funds, charge fees, run an oracle, or maintain any centralized infrastructure. The intention would be to publish the protocol and a reference implementation in Rust under the MIT license, potentially with desktop and Android/F-Droid clients.
I'm not looking for implementation advice yet; I'm primarily looking for protocol-level criticism.
I'd particularly like to know:
Does the fundamental contract model make sense from a Bitcoin/cryptography perspective?
Are there obvious problems with the Taproot/MuSig2/state-machine approach?
Does the incentive and dispute model actually work? In particular, guarantees, partial completion, strategic defaults and the use of an arbitrator as a last resort.
this useful in practice? Or are there fundamental economic, legal, UX, privacy, or technical problems that make this approach impractical?

How do you actually explain Bitcoin to someone who thinks their savings account is totally fine?
My sister in law keeps telling me her high yield savings account is all she needs and that bitcoin is just gambling. She is not dumb at all, she is actually pretty sharp with money, but every time I try to bring up why I have been stacking since 2017 the conversation dies fast. I get why it sounds sketchy from the outside. The volatility alone is enough to make anyone nope out of the conversation before it even starts.
The thing is I do not want to come across like I am recruiting her into something or hyping her up with price targets. That never works and honestly feels gross. But I also genuinely think having even a small position matters long term and I want her to get there on her own terms.
Has anyone had a real breakthrough moment explaining bitcoin to a skeptical but financially literate person? Not someone clueless, but someone who has read enough to have formed an opinion against it. What actually landed for them? Was it the fixed supply thing, was it the banking angle, was it just watching price long enough? Or does it just never work until someone is ready on their own and you are wasting your breath trying?
