Valid Range: 0 <= nValue <= 21,000,000 * 100,000,000.
How can the existing protocol handle potential future scenarios where the limited supply of 21 million BTC might pose challenges, especially considering global adoption & increasing demand ?
/** No amount larger than this (in #satoshi) is valid.

* Note that this constant is *not* the total money supply, which in #Bitcoin

As you rightly pointed out, each bitcoin is divisible by 100,000,000, so that doesn't seem to be a real problem to me. People will use satoshis
Lack of more units isn’t the problem when they’re divisible.
Bitcoin's divisibility into satoshis provides an inherent advantage. With each bitcoin comprising 100M satoshis, the flexibility for microtransactions & global trade is unparalleled.
For satoshis to hold substantial value, Bitcoin's overall market cap must increase. So, it would lead to more US dollars being printed by the Federal Reserve to regulate the fiat stability.
Let's consider BTC's Total Supply is 21MBTC, Value of 1btc:
The concept of satoshis becoming a global currency unit isn’t just about 'divisibility'; it's a paradigm shift requiring collective consensus & adaptability…
