The longer you stay in the crypto market, the more you realize that contracts are a paradox. Contracts amplify your position size but also magnify your emotions. Once you incur a loss, it's impossible to think rationally, leading to reckless operations and ultimately losing everything. So what if you try small positions for trial and error? Many people suggest this because small positions won't significantly impact your emotions, making it more likely to judge timely and make reasonable take-profit and stop-loss decisions. But the problem is, small positions can earn money, but not much. Instead, you still spend most of your day watching K-line charts and news, which results in little profit but still consumes a lot of energy—still not worth it! Especially if you think that the operational mindset for small positions can be scaled up to large positions, that's too naive. Because as the position size increases, emotional impact also grows, and operations will still distort. So contracts themselves are a paradox: large positions lose big money, small positions earn small money but still drain energy. Veteran crypto traders actually no longer rely on contracts to make money; they diversify with spot holdings and financial management for long-term sustainability.
