A fren invested $10,000 in Ethereum in 2015 and has held it until now, with the account showing $200 million. Sounds simple, right? Just hold on to it.

But when you really draw out the yield curve, it's despairing. You think holding coins is simple, but in reality, it's a psychological hell:

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

Did you see that? Dropped from 30 million to 1.2 million, crashed from 93 million to 5.3 million, and plummeted from 323 million to 54 million. Imagine how difficult it is to maintain composure during this process. Not everyone can withstand this kind of meat grinder.

In contrast, some cryptocurrencies, like a friend of mine who encountered a specific token, made a bit of living expenses overnight and quickly pulled out. His logic is very pragmatic: if you can secure profits, don't be greedy.

The market is like this; for some, it's a practice course, and for others, it's an opportunity to make quick money. The key is to understand how much psychological turbulence you can withstand.
