Cryptocurrencies have become a hot investment that is gaining mainstream adoption. Markets for digital currencies such as Bitcoin (BTC +0.07%) were virtually unheard of in 2012, but they have since grown into a massive industry.

The cryptocurrency sector reached a market value of $3 trillion in the fall of 2021 and has continued to rise to a total market cap of roughly $3.9 trillion. The sudden surge in value and rapid evolution created immense wealth for early crypto investors.
Everyone wants to know which token will become the next Bitcoin or Ethereum (ETH -1.06%). With thousands of active cryptocurrencies on the market, investing in technologies linking the digital blockchain space with society could be even more lucrative. And there is no shortage of innovative companies and investment vehicles trying to bridge the gap between the two.
