BTC and Ethereum are indeed relatively safe options. But the reality is, very few people can truly stick with it.

Whenever the market adjusts, self-doubt creeps in. When prices are rising, people are reluctant to reduce their positions. I've seen many hold Bitcoin from $60,000 all the way down to $15,000, only to give in at the $20,000 level and finally cut their losses and escape. That kind of feeling is probably hard for those who haven't experienced it to understand.

If you're at this point and truly plan to hold long-term, there's one thing you must do—strictly follow your plan. Never give back the profits you've gained; take profits when you decide to take profits.

Don't think about using the saved money to bottom-fish small coins. Those projects have a much higher chance of going to zero during a real bear market cycle than you might think.

While BTC and ETH are relatively risk-averse, the biggest opponent throughout the entire holding cycle isn't market volatility, but the person in the mirror. The twists and turns of your mindset are the real test.
