Michael Saylor proposed a vision for nation-states to build banking systems backed by Bitcoin, using reserves and tokenized credit markets to offer regulated accounts with higher yields.

The plan promises greater transparency, potentially higher returns for savers, and a decentralized alternative to traditional banking infrastructure.

Key risks include Bitcoin's price volatility, regulatory and monetary-policy challenges, and the need for major institutional adoption and oversight.

If adopted, the idea could reshape national finance systems and spark wider experimentation with crypto-backed public banking, but implementation will be complex and slow.
