Last week, I had a small gathering with friends. He was holding a glass of wine, voice a bit choked up: "$ETH contract has been messed with so much recently, the account is only left with 3000U. If this keeps up, I really want to give up."

He's been in crypto for two years. He's not a newbie, but the problem is he always makes random decisions based on feelings—chasing highs, cutting losses, going all-in. He can lose half a year's salary in a day, leaving his account in shambles.

I pointed to his phone: "3000U isn't the capital, it's the spark for your comeback."

Many people dream of a "hundredfold coin."
