As a long-term participant, these points must be remembered: First, stick to compliant leading exchanges; avoid small platforms no matter how attractive they seem, as risks are hard to guard against. Second, only use idle funds for trading; never think about borrowing or leveraging heavily to turn things around—that's digging your own grave. I personally avoid high-risk instruments like derivatives and leverage; listen to insider news but don't rely on it. The truly valuable approach is to thoroughly research projects. Don't take safety lightly: keep your private keys secure, enable two-factor authentication, and be vigilant against phishing scams. Lastly, no matter how big the market fluctuations, stay rational—your mindset is the final moat of protection.
