Thank you very much for your answers, Brother DooMAD is right. The people who hold these addresses may all be believers, just like when Nakamoto was founded, life will end at any time, but Bitcoin will always exist. With the private key in mind, I have a learning mindset to understand Bitcoin, and it may be difficult to have it in the future, after all, the price is too high. Although I don't have it, I hope Bitcoin and forums will become better and better. I hope I will have it in the future.
