The most detailed factsheet among three providers checked lists hit rate, best trade and worst trade — but not how far the portfolio fell or for how long. Five questions that make a return readable.

A leverage backtest rarely shows more return – often less. Why effective exposure = position × leverage decides, and where 5× would have liquidated your strategy in 2018.

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.

Most trading strategies are sold to you as complete solutions. "Run this system, make money." Enter signal. Exit signal. Repeat. Base rate win percentages plastered across the landing page.

Asking which company is well-positioned in the AI drug-discovery race is really three questions at once. We sort the field soberly into shovels, bets, and giants — and show which layer earns regardless of any single trial outcome.

A thesis says trading platforms are going "agentic" — AI monitors, signals, executes. The structural part is right. The blind spot sits where money is lost.

"Invested in AI healthcare" can mean two almost opposite things. Two real companies show it: an annuity machine with ~86% recurring revenue — and an option with not a single approved drug. Same label, opposite risk DNA.

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.

A new strategy for altcoins is live: trade any alt with RSI(14) / SMA(14) computed on BTC/USDT instead of on the alt itself. The idea: BTC is the bellwether — when the macro regime is on, trade alts; when it isn't, get out.

34 of 50 top-50 alts have lost money on average across every entry point — measured in USD. One strategy flips that. It doesn't look at the alt. It looks at BTC.

We tested our RSI/SMA strategy on 77 actively trading Binance BTC-pairs (XAUT and WBTC excluded). 92% of them lost against BTC over 8 years. The strategy still beats Buy & Hold on 88% of pairs — through getting out, not through outperformance.

Buy now or wait for the dip? Both camps believe in rising prices — yet pursue opposite strategies. An expected-value calculation reveals which one actually wins, and under which conditions the math flips.
