Backtesting Arena Is Now a Claude Connector
Backtesting Arena can now be connected to claude.ai with a single click — 65 tools for Bitcoin cycle, on-chain data, macro regime and validated backtests. Instead of generic web-search answers, Claude pulls real, DSR-corrected and point-in-time data. Plus a new interactive tool: the Dip Decision calculator.
We Just Shipped an API That Charges $0.01 Per Call — In USDC, On-Chain, No Account
Phase 4 is live: the same Bitcoin cycle data, on-chain indicators, and aggregated strategy insights now reachable through three channels — REST, MCP, and x402 pay-per-call in USDC on Base. No account required for the third. An AI agent gets HTTP 402, signs a USDC authorization, retries, and has the data three seconds later. What's actually live, why we built it this way, and the Coinbase detour that cost us a day.
Your Ledger passed the genuine check. Is it safe? The check tests the chip, not what sits next to it in the case
In October 2026, attackers emptied wallets that had been set up on Ledger devices from the reseller CryptoBilis. The devices were genuine and passed Ledger's genuine check. Inside the case sat a radio module that read the 24 words off the screen during setup.
Do you need a privacy coin, or can Bitcoin already keep your payments private?
Bitcoin can already hide who gets paid and which coins belong together. It cannot hide how much. Zcash and Monero can, and each pays for it somewhere you should know before you buy.
How Does Leverage Trading Work – and Why a 2x Never Doubles Your Asset Holdings, but Can Cost You Everything?
Count in units of the asset, not in dollars: holding 1 coin always leaves you 1 coin. A 2x long gets closer to 2 the higher the price climbs, but never reaches it, and a halving takes everything. That holds for every asset. Since 2017, a 2x long would have been liquidated within a year after one in three entry days for Bitcoin and almost one in two for Ether.
No blockchain is fast, secure and checkable by anyone at once. Bitcoin, Ethereum and Solana each pay somewhere else.
Why doesn't Bitcoin just get faster? Because speed costs something else. The blockchain trilemma, the ways around it, and the one number to watch for Bitcoin, Ethereum and Solana.
The AI Copilot in Your Chart Is Reliable When It Measures and Invents When It Describes Itself
TradingView's chart copilot can connect to your own MCP servers. Tested on the Backtesting Arena connector: it answered market questions correctly and invented instructions about its own settings four times. Why that happens, and how to tell which answers to check.
Agent Payments: Why No Standard Checks Whether the Work Was Any Good
Agent payments are standardised: authorisation, identity, mandate, settlement. Whether the work was any good, nobody checks. Why that is a boundary and not a gap.
Building for AI Agents: 10 Lessons From Running 73 MCP Tools
Your most thorough reader gets the least to read. Ten places where building for agents differs from building for people, with numbers from production.
DCA vs. Lump Sum: What 346 Bitcoin Entries Actually Show
DCA vs. lump sum for Bitcoin? Across 346 historical entries the lump sum won 60 % of the time — but DCA halved the downside. The distribution instead of an opinion.
Oracle Manipulation in DeFi: What Happens When a Protocol Trusts Bad Data
Oracle manipulation drained millions from Ostium — not through a contract bug, but through bad data. The failure modes when DeFi protocols trust their price feeds.
Consensus Is Not an Edge: Why a Quorum of Correlated Simulations Isn't One
An AI swarm turned $1,000 into nearly a million? The number falls apart at its own source. Why consensus from correlated simulations is not an edge.
