What were you doing in 2009? Every time I open the BTC URPD full-chain data, I am filled with emotion... timestamp: 2009/1/3 00:00; total_supply: 50 — This is the Genesis Block of 2009-01-03, where Satoshi Nakamoto mined block height 0; the block reward was 50 BTC; which is the starting point of the Bitcoin network. On January 9, 2009, Satoshi Nakamoto released Bitcoin Core v0.1 in the mailing list; from that day on, anyone could participate in mining simply by downloading the program. At this time, we see that total_supply has become 750. From January 10th to 11th, 2009, Hal Finney downloaded and ran the Bitcoin program. On January 10th, 2009, he tweeted: "Running bitcoin"; this marked the first time in human history that someone other than Satoshi Nakamoto was actually mining Bitcoin. At this time, total_supply had grown to 8450. In the early days of 2009, the reality of mining was: using a regular CPU, the difficulty was approximately 1, and one person could mine several thousand BTC per day. The total network hashrate was approximately equivalent to several home computers. Six months later, on July 22, 2009, total_supply surpassed 1 million for the first time! No one realized what had happened that day. Why do I feel emotional? Back then, all I knew was how to play "Legend of Mir" every day. Even if I had a tiny bit of understanding, I'd just leave a thread running, playing "Legend of Mir" while mining... Years later, I became a legend 🤣🤣🤣 Alas, indulging in frivolous pursuits leads to the loss of ambition...

You can't say that; you gained happiness 🤣.
