There's no textbook SaaS pitch behind Backtesting Arena — just the simple question every serious trader asks after enough cycles: which rules would have actually kept me out of the worst losses? An honest origin story.

A new app called Tando bridges the Bitcoin Lightning Network directly to M-PESA. The recipient gets Kenyan shillings on their phone — no wallet, no seed phrase, no KYC. Lightning's killer feature isn't speed. It's invisible infrastructure under rails people already trust.

TradingView is excellent for charting and visual analysis — but for the question whether a strategy systematically works across assets, it isn't built. Why fast, comparable backtesting requires a different class of tool.

Payment systems are being fundamentally rebuilt right now. The driver isn't crypto — it's AI. What Visa, Mastercard, AWS, and Citi are pivoting toward simultaneously, and the architecture taking shape for the next decade.

Self-custody of Bitcoin has a problem rarely discussed: what happens to your coins if something happens to you? We look at how Miniscript, the Liana wallet, and the BitBox02 address this technically — and where the limits are.

Anyone serious about Ladder Stacking eventually opens a spreadsheet: check Z-Score, find multiplier, compute amount, buy, log it. Every week. We built a live tracker that takes over — weekly alert with concrete action recommendation, confirm/skip/edit, performance vs HODL and Static DCA. Pro+ feature.

The trading-tools market splits into two philosophies. They look similar from a distance, but they're fundamentally different things.

Grid bots promise profit from sideways markets — but without the right range they fail. We show with two real BTC backtests (2024 and 2025) when grid wins, and when buy-and-hold dominates.

Sell, borrow, or borrow-and-buy more? Three strategies with real numbers, stress-tested against the Bitcoin Power Law.
