GYEN is a stablecoin that is pegged to the Japanese Yen. In order to keep the same price as Yen, GYEN uses a complicated set of trading strategies to make sure the value of Yen and GYEN match. This is called an algorithmic stablecoin. While algorithmic stablecoins are convenient they can be risky if something happens that makes the algorithm not work anymore. Something like this happened when Coinbase listed GYEN. Some crypto traders did not realize that the coin was supposed to be a stablecoin and its price fluctuated significantly away from its pegged value. Many investors were understandably upset with Coinbase for offering a coin that wasn’t supposed to change value. They were even more upset when a coin that was supposed to be a stable price went up and down very rapidly. It goes to show that in crypto, even stability is volatile.
