For people investing in crypto assets, nine out of ten have fantasized about overnight riches. But frankly, very few actually manage to lock in their profits. Most people's problem isn't choosing the wrong coin; it's their trembling hands when it's time to take action.

In 2017, I experienced a rollercoaster market. At that time, ADA wasn't yet a mainstream asset. I bought in at several batches around $0.03, thinking this was the bottom. In less than three months, ADA surged to $1.2, and my paper gains nearly 40 times. Can you imagine? Every day I woke up and looked at my phone, the account numbers kept changing. All I could think about was buying a house and financial freedom — I was floating on air.

But the market doesn't indulge you. Before I could actually cash out, ADA started to plunge. In just a few weeks, it dropped from $1.2 to $0.2. Those seemingly foolproof plans suddenly became just a pipe dream.

It was only later that I realized the biggest enemy in the crypto market is never the market itself, but our own greed. The crazier the rise, the more ruthless the fall. The bigger the gains, the lower our risk tolerance. Those who survive are the ones who stay rational amid the madness, hitting the brakes before temptation takes over. This is a trading principle learned through paying tuition with real money.
