最新报道:Bitcoin challenges the U.S. dollar as a digital alternative, differing fundamentally in supply and control. The dollar has unlimited issuance managed by the Federal Reserve, with nearly 30% of circulating supply created since 2020, raising inflation concerns. Bitcoin’s fixed cap of 21 million coins, with under 5% left to mine, ensures scarcity akin to gold. While the dollar relies on centralized trust in banks and governments, Bitcoin operates through decentralized, transparent blockchain technology, eliminating intermediaries and shifting trust to open-source code.
