For thousands of years, gold has been the international currency, and for good reason. Gold is a substance that is in high demand and there is a finite amount that can be produced.
Bitcoin, through cryptography, was created on these very principles. Bitcoin must be mined, is in high demand, and there is only a finite amount that is available – just like gold.
Relative to its short history, Bitcoin has made a significant global impact and has become popular with those who seek an alternative to fiat currency. Only time will tell which has more upside: bitcoin or gold.
