Grid bots are marketed as "low-risk" and, with AI, as a source of "consistent profits." We checked the claims against the mechanics: a grid earns on sideways oscillation, not trends — and "always trading" means trend-chasing. A fair breakdown, plus how to actually evaluate a grid bot.

High funding rates signal overheated longs — a warning. Negative funding means shorts capitulating — a buy signal. The logic seems solid. We tested it across 6.7 years of BTC data. The results were the opposite of what we expected.

A new strategy is live: John Bollinger's classic volatility-cycle play. Wait for the bands to squeeze tight, then ride the long breakout above the upper band. Default 20/2.0/0.1. Pro+.

Most traders writing their own backtests accidentally look into the future. The result: spectacular backtests, collapsing live performance. A look at the subtlest methodology mistake in systematic trading — from the common `shift(-N)` to the innocuous `.mean()` aggregation without rolling window — and why we manually check every Backtesting Arena strategy for bias before release.

"AI-crypto" trades as one sector but is at least four different things on different layers of the stack: payment rails (Solana, Base, Sui, Tempo), agent frameworks (Virtuals, ElizaOS, Fetch/ASI), decentralized intelligence (Bittensor) and decentralized compute (Render, Akash, io.net). A map of the most relevant projects per category — and one test cutting across all of them to show where real substance sits and where a narrative was simply built around a token: is the token structurally necessary, or just present?

AI agents pay per API call, per query, per compute slice — median $0.01–0.10. That kills card rails and makes the blockchain architecture the real question. A detailed comparison of Ethereum, Solana and Sui against the actual requirements (sub-cent fees, sub-second finality, programmable spend limits, identity) — plus the purpose-built payment chains Tempo and Arc that may be technically further ahead but barely adopted. The honest answer has no single winner.

A buy signal fires — but the unlock calendar says a large tranche of supply hits the market in nine days. Do you take the trade? Using Hyperliquid and the FDV debate as the case: what the FDV-to-market-cap ratio really means, what token unlocks empirically do to price — and the one point-in-time trap that quietly makes almost every retroactive test worthless.
