This article explores the revolutionary design principle of Bitcoin, emphasizing its finite supply limit of 21 million coins as a key feature distinguishing it from traditional currencies. Unlike central bank-controlled fiat currencies prone to inflation and value depreciation over time, Bitcoin's scarcity and capped supply make it an excellent asset for value preservation. The article delves into how Bitcoin's supply mechanism, including the halving process, ensures a slow and steady release of new coins, mirroring qualities of precious metals like gold for long-term value storage. This scarcity, coupled with increasing demand, positions Bitcoin as a compelling investment for wealth preservation in the digital age, free from the influence of centralized monetary policies.
