Is there a positive-expected-value strategy in the crypto market? Yes, but none of them are called 'coin trading.' Quantitative arbitrage — You need programming skills, millisecond-level servers, and at least $100,000 to start. This isn’t called coin trading; this is running a quantitative fund. Market making — You need licenses, large capital, and a complete risk control system. This isn’t called coin trading; this is financial business. Primary market — You need VC-level project screening skills, an industry network, and the mental readiness to see 90% of projects go to zero. This isn’t called coin trading; this is venture capital. Notice something? Every positive-expected-value strategy sounds like something retail investors can’t do. Because it isn’t. The only positive-expected-value move retail investors can make is this: dollar-cost average into BTC and hold. Not sexy, but mathematically sound.
