If Bitcoin is theoretically infinitely divisible, with a fixed supply, then even if there was 1 Sat left, surely that could be divided into an infinite number of “Micro-Sats” for anyone to use (and so on). If Bitcoin does eventually become a major “unit of account”, then the volatility likely becomes slightly more invisible to the people using it as a medium of exchange (like in the @joenakamoto documentaries about the mountain village in Peru). Plus, at that point, if a whale dumps, surely the market will rush to absorb the released cheap Sats… Food for thought.
