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. ...
