If you had spent $10,000 on ETH in 2015 and held all the way to now, it would have turned into $200 million. It sounds easy: just hold on, right? But if you really chart the profit curve, you'll find that the emotional journey is completely beyond what a person can endure: 10,000 → 1,000,000 → 14,000,000 → 390,000 → 30,000,000 → 1,200,000 → 93,000,000 → 5,300,000 → 323,000,000 → 54,000,000 → 200,000,000. Ask yourself again: can you really hold on?
