What can I buy after selling Bitcoin?

In the interview, Duan Yongping spoke about Moutai again. He said that in 2021, when Moutai's stock price was around 2600 or 2700 yuan, he really wanted to sell his Moutai because he felt the price was too high. However, when he actually decided to sell, he struggled with the decision for a long time because: He really didn't know what to buy after selling Moutai. Hearing this, I thought it was a familiar story, as I had seen similar statements in his Q&A sessions before. But his next statement answered a long-standing question that had been lingering in my mind. He said (in essence): If he sold, holding the cash would be very uncomfortable because he's always fully invested in stocks. So, if he held the cash, he'd most likely buy other stocks, but if he bought other stocks, there's a high probability that those stocks would perform worse than Moutai. He believes Moutai will continue to rise, but if he buys other stocks, it's hard to say. Therefore, he held onto Moutai and didn't sell. After listening to this interview, I recalled two past experiences. Once, during an earlier bull market, I happened to sell some cryptocurrency at a relatively high price and received cash. But later, due to various reasons, I couldn't control myself and bought recklessly, losing a significant amount. Later, when the bear market arrived, and I realized the value of Bitcoin and Ethereum, the funds I could actually use to buy them had significantly decreased. Then, when the bull market came, none of the coins I had haphazardly bought ever reached their former glory levels. It would have been better to sell them and directly buy Bitcoin and Ethereum. Although Bitcoin and Ethereum also plummeted during the bear market, they will eventually reach new highs in the subsequent bull market, bringing me surprises once again. The second time was during that bull market. After selling Bitcoin and Ethereum, I retained most of my funds, which I then used to buy back Bitcoin and Ethereum during the subsequent bear market. Looking back on that second experience, I realize that I wasn't able to retain those funds because I now understand Duan Yongping's reasoning: buying other stocks/cryptocurrencies might be worse, and it's better not to hold onto Moutai/Bitcoin and Ethereum. It was probably more about luck and intuition. But after hearing Duan Yongping's explanation, I understand his decision not to sell Moutai much better. For many, selling Moutai/Bitcoin/Ethereum at a high price might be relatively easy. The real challenge lies in maintaining composure when you have a large amount of cash on hand, controlling your impulses, and avoiding buying things you don't understand or think you understand but actually don't. I suspect many of our readers are like this: taking profits at a good point, but then squandering the cash by buying haphazardly, resulting in either losing everything or never regaining its former glory. Now, thinking about it, instead of randomly buying various assets, why not just buy Bitcoin and Ethereum? Furthermore, recalling when I started my dollar-cost averaging (DCA) in 2022, instead of investing in so many different assets, it would have been better to focus my DCA solely on Bitcoin and Ethereum. Additionally, I also wondered: Even if you could sell your Bitcoin and Ethereum at the peak of this bull market, when you have a large sum of cash, can you control yourself and guarantee that you won't recklessly spend that money or buy various assets during the bear markets of the following years? The best-case scenario, of course, is to strictly control yourself, keep cash on hand, and honestly buy back your Bitcoin and Ethereum in the future. But if not, why not simply hold onto those Bitcoin and Ethereum without selling them?
