The explosion of cryptocurrencies and their meteoric returns over the last several years is causing some investors FOMO (fear of missing out). While cryptocurrencies, mostly Bitcoin, are in the news every day, very few investors understand their potential and the technologies that enable them. Rather, many are attracted to the highly-publicized returns they have generated in a very short amount of time. This has created something of a flywheel effect -- some may call it a bubble -- in which more investors are chasing these returns, which then drives returns higher, which then attracts more investors.
