Pi Cycle called four Bitcoin tops. The all-time high wasn't one of them.

In crypto, a strategy's first job is the exit. 200,000 backtests show why.
Across 405 crypto pairs, buy and hold loses money on 83 % of them. What 197,435 backtests say about what a strategy does first, what decides whether it earns, and why the bar for any altcoin is Bitcoin.

Screeners label altcoins "uptrending vs BTC" and stop there. We measured what followed the label across 370 pairs and 458,000 days — and what followed any day.
Leverage Backtest: Why More Leverage Rarely Means More Return
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.
Stacking More Sats With Altcoin Rotation? 45 Tests, One Answer
Stacking more sats by rotating between altcoins, BTC and stablecoins sounds compelling. We measured it across 45 test cases. The result: less BTC than doing nothing.
