[Michael Saylor: Bitcoin is the Engineered Solution to Monetary Problems] Michael Saylor published an article titled 'What is Money?' on X, stating that money is essentially economic energy, used to store the value created by humanity and transfer it across time and space. He believes that gold is constrained by physical friction, fiat currency is limited by political intervention and inflation, while Bitcoin, through its fixed supply, cryptographic security, and proof-of-work, can preserve and transfer economic energy with lower loss. It is the 'digital monetary energy' and an engineered solution to monetary problems.
