Having spent eight years in this industry, the deepest lesson isn't how much I made, but the helplessness of watching profits slip through my fingers time and again.

During the 2017 wave, I went all-in on ADA. From $0.03 to $1.2, my account skyrocketed nearly 40 times in three months. During that period, I was crazy—every day as soon as I opened my eyes, I checked my balance, even marking the location of the Porsche dealership. And then? I watched it drop to $0.2, with profits almost completely wiped out. The moment I fell from the clouds, I truly understood—being able to buy is just luck; being able to sell is the real skill to survive.

After that, I started to reflect seriously. Losing a lot naturally made me wiser. Every step I take now is paved with lessons learned.

**Key Tip: Ladder Take-Profit, Don’t Bet on the Top**

Not being greedy keeps you steady. I no longer wait for the highest point but execute phased take-profits: when the coin price doubles, sell 30% to recover the principal and ease the nerves; when it triples, sell another 30% to lock in medium-term profits; the remaining part is set with a trailing stop—if it retraces 15% from the peak, I automatically exit.

In practice, combining trend reversal take-profit methods makes it more responsive. When the price hits an important resistance level, I focus on observing whether there's a sign of market reversal. Once confirmed, I immediately take profit. This way, I avoid greedily chasing the last bit of gains and also prevent getting trapped.

**Iron Rule Two: 5% Stop-Loss, Like Wearing a Seatbelt**

Stop-loss is more important than take-profit. Setting a 5% stop-loss isn’t because this number is sacred, but because it allows you to keep playing. If the loss exceeds 5%, cut your losses decisively—no room for regret. I never break this rule—just like always wearing a seatbelt when getting in the car.
