Bitcoin is thermodynamically sound money because it’s created through the use of real-world energy. Powerful specialized computers (ASIC Application-Specific Integrated Circuit Computers) around the world compete to solve complex problems, and that process burns electricity - a physical cost that can’t be faked. This energy requirement gives Bitcoin a foundation in reality. Unlike dollars, which can be printed endlessly, Bitcoin must be earned through Proof of Work. That makes it honest, limited, and resistant to manipulation. It’s money that obeys the laws of physics - not the decisions of a central authority.
