The 80,000 bitcoin old miners woke up after 14 years of sleep, and everyone must have swiped it. I was curious to pick up the address, in fact, there is currently [no direct evidence] that this is a miner from China. To be honest, there were relatively few miners in China in 11 years, because at that time, not to mention Bitmain, even Pumpkin Zhang had not yet invented the Avalon mining machine, and the American butterfly mining machine had not come out (this was all in the middle of 2012), and the roast cat was still after. And Chinese miners will start to dominate, at least until these ASIC miners are concentrated in China. And I think most of the miner's transfers were made in the first half of 2011, when he was really in the idyllic stage of ordinary equipment mining envisioned by Satoshi Nakamoto. And why is he most likely a miner? It's because he has a lot of behavior to aggregate block rewards. These 50 BTC are all newly mined block rewards at that time, and they are pure bitcoins. Then, another interesting point is that the old miner used Bitcoin addresses starting with 1, and now he has transferred them all to addresses starting with bc1. So, what is the difference between addresses that start with 1, 3, bc1, and bc1p? At the beginning of 1, Satoshi Nakamoto's earliest invention based on base58-based address, the classic skin. PS: The so-called Base58, compared to Base64, Base58 does not use confusing letters, the number "0", the letter capital "O", the letter capital "I", and the letter lowercase "l", you can find it casually, Bitcoin address never includes these alphanumerics. See, Satoshi Nakamoto made a good amount of advance for us handicapped parties at that time. After 2017, Segregated Witness (Segwit) was capped, which allowed Bitcoin to put some secondary transaction information outside the block, breaking through the 1MB block in disguise, and achieving soft scaling. BC1 and 3. As a result, the native address bc1 of the native Segregated Witness was born, and the transfer of BC1 to BC1 will make the transaction fee nearly half cheaper. And in order to take care of the people who don't like SegWit, the forward compatible version was born, that is, the address that starts with 3, and the beginning of 3 is also lower than that of 1. Due to the Segregated Witness, the fee is sorted by: BC1 > 3 > 1 In addition, the BC1 address is relatively more secure, not from the perspective of anti-cracking - the anti-cracking ability of these 3 addresses is the same, but that the BC1 address is more secure in terms of verification. 1. This bc1 address is all lowercase, which avoids the trouble of being case-sensitive for Bitcoin starting with 1 or 3. 2. This BC1 address has a better validation mechanism, which reduces the possibility of errors when entering the address. For example, if you mistakenly enter a bc1 address, the system is more likely to find and fix the error, while an address that starts with 1 or 3 is less likely to be validated. As for the bc1p address, it is the address that supports Taproot, and Taproot I shared before that you can flip through it if you are interested. ---- Dividing Line---- From this point of view, it is also difficult for me to believe that the miner "went to jail". Because if I were a jailed person and I had been out of touch with society for so long, I would probably choose an address that starts with 1, and it's hard to trust a bc1 address, even though it's safer. Only those who have lived through the strife of the SegWit era will recognize SegWit, especially the native SegWit address, BC1. Anyway, he has 8w bitcoins, and there is no difference in transaction fees at all. Of course, these are just my guesses, and it is possible that the Bitcoin wallet he uses is bc1 by default. It's just that I think the person who was interested in Bitcoin in 2011 was probably a geek. And this kind of geek, or early supporters of Bitcoin, has a political tendency towards Bitcoin. And using addresses that start with different ones is also part of the political spectrum that represents oneself in Bitcoin. Of course, in the end, there is a simple hope 😂, hoping that he will just change to a better and more advanced address, instead of preparing to ship and leave.
