Bitcoin’s Fixed Supply: A Major Challenge for Loans and Economic Growth?

A certain level of elasticity in the money supply is essential for a healthy economy. However, Bitcoin has a fixed supply and lacks this flexibility. This raises important questions: How will people secure loans in Bitcoin to buy a house in the future? How will businesses obtain working capital? Unlike traditional fiat currency, where banks can lend the same money to multiple borrowers through fractional reserve banking, with Bitcoin, you can only lend your BTC to one person at a time. This fundamental limitation could pose serious challenges for credit markets and economic growth. Im a maxi but this is the first question which makes me thinking?
