.0021 Bitcoin is 210,000 Sats or $210 USD when BTC is at 100k. It's an amount that most people in the developed world could get to, either by saving, selling some things, or just as a part of their investments. It's also roughly the amount of Bitcoin that all 8 billion people would have if Bitcoin were distributed equally, accounting for lost coins. Infact it's probably more because plenty of people, corporations and nation states will hold more than that and never sell down to that amount of sats. It's an amount that once you hold for a while you will question why you dont own more.
