Cryptocurrency has been getting a lot of headlines in the financial press the last few years, and I am often asked about investing in it. Many investment advisors expected the glory days of digital currency to be long over by now, yet it continues to get stronger, increase in price, and find a broader following.

What’s up with crypto, and should it be in your portfolio?

What is cryptocurrency? It is one form of digital currency, money that exists only in electronic form which may not be controlled by any country's central bank. There are three types of digital currencies:

1. Cryptocurrency, such as bitcoin and ethereum. A unit of currency is an encrypted data string, created or "mined" by computers solving complex digital problems. A computer network called a blockchain maintains the currency, securely records transactions, and limits the creation of new currency.

2. A virtual currency is always unregulated, and it is controlled by its developers.

3. A central bank digital currency (CBDC) is created and regulated by a country and is legal tender in that country. According to a July 22, 2021, article on Axios, 16 countries, including China, are in the pilot phase or have launched a CBDC, and 15 others have CBDCs in development.
