Cryptocurrency
Cryptocurrency, such as BitCoin, is a digital asset that provides an added layer of security for transactions. You may have had a couple of friends own some BitCoin and brag about the price skyrocketing during the early 2010s. The problem with this decentralized currency is the ease of hackers to steal digital dollars. It creates volatility in its value, making it a more significant risk than a reward. However, that probably won’t stop your friends from claiming to be experts.
