There is a case circulating online: an investment of $10,000 in ETH in 2015 has risen to $200 million today.

It sounds simple and straightforward - just hold on and that's it.

But if you fully expand this profit curve, you'll understand how disastrous the real experience of those 100,000 ETH was:

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

From paper profits to nine-digit losses and then back to square one, this rollercoaster-like volatility tests not only market judgment but also the psychological bottom line of investors. Long-term holders in the cryptocurrency space must acknowledge a reality — every plunge in the market cycle can potentially breach the psychological defense line. Those who end up laughing last are often not the ones with the strongest predictive abilities, but rather those with the greatest psychological resilience.
