Is crypto a good market for algorithmic trading?

It's the most accessible market for it: 24/7 trading (no gaps from overnight closes on major venues), free high-quality historical data, exchange APIs designed for bots, and no pattern-day-trader rules or minimum capital requirements. Volatility is high, which cuts both ways — more opportunity per unit time, more punishment for weak risk control.

The honest caveats: fees and slippage are proportionally heavier than in equities for short-timeframe systems, altcoin liquidity can be thin, and regime shifts are violent. That combination is exactly why validation matters more in crypto, not less — strategies curve-fit to a bull regime die suddenly.
