$BTC friends who have been trading for many years and still haven't made a million, listen to my advice: remember these 10 pieces of practical advice, and if it doesn't work out, come find me!

1. Don't mess around with small amounts of money! It's enough to catch a big bull market opportunity once a year; don't invest all your money, keep some cash as a safety net, so you can buy more if the price drops.

2. Earn according to your understanding! Don't touch coins you don't understand; practicing on a demo account is fine, but when it's real money, the mindset is completely different. Learn thoroughly before you act.

3. Don't be greedy with good news! If you haven't sold on the day of the news, and the next day opens high, sell quickly. Everyone is waiting to cash out on good news, and a high opening is a chance to escape; if you wait too long, it might get stuck in your hands.

4. Reduce your holdings a week before holidays! During holidays, the market has low trading volume, and prices can easily spike or plunge. Don't take that risk; enjoying the holiday is more important than anything else.

5. Remember the mid- to long-term strategy: 'buy low, sell high'! Buy in batches when prices fall, and sell in batches when they rise. This way, you can lower your cost and have flexible funds on hand, so you're not afraid of market fluctuations.

6. For short-term trades, only choose popular coins! Don't touch coins with low daily trading volume; if there's no one to take your position, you could get stuck. Follow the flow of large capital; good liquidity means good profits.

7. Remember this rule: coins that decline slowly are likely to recover slowly later; however, coins that suddenly crash can rebound quickly. You can seize such opportunities but don't be greedy.

8. Be decisive with stop losses! If you buy the wrong coin, don’t hold on stubbornly; recognize your mistake and cut your losses in time. Preserving your capital gives you a chance to recover; waiting for a break-even point might lead to deeper losses.

9. For short-term trading, look at the 15-minute K-line chart! Focus on the KDJ indicator; sell when it reaches the top (overbought) and buy when it hits the bottom (oversold). Combine this with MACD and RSI for better judgment; don't rely on just one indicator.

10. Don't learn too many technical indicators! Master two or three indicators, such as KDJ and MACD, that's sufficient. Learning too many can confuse you; understanding one indicator thoroughly is better than knowing many superficially.

It's that simple; the core principle is two words: 'restrain'— restrain greed, restrain frequent trading, protect your principal, and seize big opportunities. That's more practical than anything else!
