If you don't issue coins, others will issue coins, and you will find it hard to resist buying others' coins, ultimately leading to financial ruin. In history, only Bitcoin is a masterless currency. Satoshi Nakamoto never imagined that casually issuing a virtual currency could be so valuable. Who would have thought that after 1600 years, there would finally be a currency that is a better hedge than gold, is easy to carry, better for transfers, and more scarce.
