The biggest risk when playing memecoin is earning a hundred times and then getting wiped out by a trash coin. So you need to learn the 433 rule.

When you identify a target, don't obsess over the price; enter the market first. Divide your principal into ten parts, and initially invest 4 parts as your main position.

If the market keeps rising? Stop adding to your position and take profits gradually and honestly. But if it continues to decline, with a retracement of 30% to 50% (adjusted based on the coin's characteristics), add 3 more parts. At this point, you've already invested 7 parts.

If it keeps falling? Drop another 30% or more and use up the remaining 3 parts. The ten parts of your funds are now fully invested.

What if it falls further? Then stop. Don't move anymore. This indicates you've misjudged, and you're dealing with a real trash coin. Instead of continuing to throw money in, better to accept defeat.

With this approach, you won't miss out on good coins, nor will you endlessly try to rescue yourself from bad coins. The key is to set a psychological stop-loss level and not let a single mistake ruin your overall gains.
