There is no direct evidenceProve that this is a miner from China. To be honest, in 2011, there were relatively few miners in China because at that time, not to mention Bitmain, even Pumpkin Zhang had not invented the Avalon mining machine, and the Butterfly mining machine in the United States had not yet been introduced (all of which were in mid-2012), and Roast Cat was even later. And Chinese miners have begun to dominate, at least until these ASIC mining machines are concentrated in China. And I think most of the transfers made by this miner were in the first half of 2011, when they were really in the pastoral and ordinary equipment mining stage envisioned by Satoshi Nakamoto. Why is it said that he is most likely a miner? It's because he has many behaviors of collecting block rewards. Click on these 50 BTC to take a look, they are all newly mined block rewards at that time, and they are pure Bitcoin. Then, another interesting point is that the old miner used Bitcoin addresses starting with 1 back then, but now he has transferred these addresses to addresses starting with bc1. So, what are the differences between addresses starting with 1, 3, bc1, and bc1p? At the beginning, Satoshi Nakamoto first invented a base58 based address and classic skin. PS: The so-called Base58, compared to Base64, does not use easily confused letters such as the number "0", uppercase letter "O", uppercase letter "I", and lowercase letter "l". You can easily find them, and Bitcoin addresses never include these letters and numbers. Did you see that Satoshi Nakamoto had already prepared an advance plan for us disabled people at that time. After 2017, the Segwit limit allowed Bitcoin to place some secondary transaction information outside the block, effectively breaking through 1MB blocks and achieving soft scaling. Starting with bc1 and starting with 3. So, the native address bc1 for native isolation witness was born, and converting bc1 to bc1 would make transaction fees nearly half cheaper. And in order to cater to those who do not like to witness isolation, a forward compatible version was born, which is an address starting with 3, which is also lower than the 1. Due to the use of isolated witnessing, the order of handling fees is: bc1>3>1 In addition, relatively speaking, the bc1 address is more secure, not because of its anti cracking ability - these three addresses have the same anti cracking ability, but because the bc1 address is more secure in verification. 1. This bc1 address is all in lowercase, avoiding the trouble of Bitcoin starting with 1 or 3 and distinguishing between uppercase and lowercase letters. 2. This bc1 address has a better verification mechanism, reducing the possibility of errors when inputting the address. For example, if you accidentally enter a bc1 address, the system is more likely to detect and correct the error, while addresses starting with 1 or 3 have a lower probability of verification. As for the bc1p address, it supports Taproot addresses. I have previously shared that if you are interested in Taproot, you can take a look. ----Dividing line---- From this perspective, I also find it difficult to believe the claim that this miner has "been imprisoned". Because if I were a prisoner who has been out of touch with society for so long, I would most likely choose an address starting with 1. It's hard to trust a bc1 address, even though it's safer. Only those who have experienced the disputes of the era of quarantine witnessing will recognize quarantine witnessing, especially the native quarantine witnessing address bc1. Anyway, he already has 80000 bitcoins, so he's not short of transaction fees. Of course, these are just my guesses, and it's also possible that the Bitcoin wallet he used defaults to bc1. I just think that those who were interested in Bitcoin in 2011 were probably geeks. And these geeks or early supporters of Bitcoin have a political inclination towards Bitcoin. And using addresses with different beginnings is also a part of the political spectrum representing oneself in Bitcoin. Of course, in the end, there is a simple hope 😂， I hope he just keeps it at a better and more advanced address instead of preparing to ship and leave.
