Imagine if, during the early stages of the 2015 bull market, you had invested $10,000 in Ethereum and then did nothing, just held on to it. Looking back now, that investment has grown to $200 million.

It sounds incredibly simple: pick the right coin, hold on, and win.

But if you lay out the actual profit curve, you'll find that this path is not something human willpower can sustain:

10,000 → 1,000,000 → 14,000,000 → 390,000 → 30,000,000 → 1,200,000 → 93,000,000 → 530,000 → 323,000,000 → 54,000,000 → 200,000,000

This is not just numbers jumping around; it's psychological torment. From the joy of a thousandfold increase, to the despair of a 90% decline, and then to rekindled hope—how many times does this cycle repeat?

So the question isn't about which crypto asset to choose, but rather: when your account drops from its peak back to rock bottom, can you really grit your teeth and stay strong?
