In the more than 10 years since the emergence of cryptocurrency on February 3, 2026, there have been countless stories of sudden wealth. As a result, many people think that making money is a normal thing, but the reality is quite different. Even with this cycle's multi-fold gains in Bitcoin, achieving this steady return is not easy. The seemingly continuous upward trend is actually riddled with bumps, and before the main upward wave, there is a painful and long period of dormancy. Recently, everyone has been mentioning a saying: instead of struggling through the crazy wave of cryptocurrencies, it's better to really think clearly about what we are doing. Why buy Bitcoin? And why hold Ethereum? Understanding the underlying logic behind the investment is the true source of confidence to stay committed. Honestly, when I see prices plummet and my crypto assets shrink significantly, I also panic. But as long as I understand why I bought in and the source of my long-term belief, I feel much more at ease. The core value of Bitcoin as a store of value lies in its fixed total supply. In the real world, fiat currencies are constantly being issued for various reasons, and there are very few tools that can resist the dilution of cash purchasing power. Bitcoin is a great invention. Recently, I spent some time creating a video on YouTube explaining the principles of Bitcoin. Since it was my first time making a video, it’s not very polished, but for those interested in understanding Bitcoin, I recommend taking some time to watch it. I know that not many people truly understand Bitcoin, including myself, and I can't say I fully understand it either. If you're interested, you can find it on my homepage.
