This is a hard-earned lesson that cost me dearly.

Five years ago, I was also a "technical trader" who stayed up late staring at the charts, studying candlesticks, MACD, RSI... What was the result? My account went through roller coasters repeatedly, got liquidated several times, and I was stuck in place.
Until an old veteran woke me up: when trading coins, the simpler, the better. He taught me a 'stupid' method - the 343 batch buying method. At the time, I scoffed: 'Isn't this too silly?' Now, I share it with you in its entirety:
The "Dumb Method" that the dealer hates the most: 343 batch building method
Core: Do not guess the rise and fall, mechanically execute.
1. 30% Initial Position (Testing): Select mainstream coins (such as BTC, ETH) and initially buy 30% of the total funds. Key point: Never go all in!
2. 40% Replenishment (Cost Reduction):
If it rises: do not chase the high! Be patient and wait for a correction to add 40%.
If it drops: for every 10% drop, add 10% of funds until 40% is replenished. Logic: the deeper the drop, the lower the cost, and the greater the rebound profit.
3. 30% Closing (Adding Position with the Trend): When the cryptocurrency price rebounds and holds above key support (such as the 7-day moving average), decisively enter the remaining 30%.
Finally: Set a trailing stop to let your profits run!
Why is this "stupid" method effective?
Do not predict, just follow: give up subjective judgment and let the market lead the way.
Place bets in batches to diversify risk: avoid being trapped by a single large investment.
A drop is an opportunity: the more it falls, the more you buy, lowering the cost, and the rebound will be stronger.
