You can invest in blockchain through digital assets that represent blockchain technology. The digital assets are mainly cryptocurrencies like bitcoin, ethereum, and ripple. Many investors are buying and holding bitcoin because they see it as a type of digital gold.
Like gold, the bitcoin supply is limited. Bitcoin’s value may only increase as the demand outstrips supply. For example, only 21 million units of bitcoin will ever exist. As of September 2020, 18.5 million units of bitcoin had been mined, which means that only 2.5 million more units remain to reach the bitcoin supply limit.
