“Last week TerraUSD, a stablecoin — a system that was supposed to perform a lot like a conventional bank account but was backed only by a cryptocurrency called Luna — collapsed. Luna lost 97 percent of its value over the course of just 24 hours, apparently destroying some investors’ life savings.
The event shook the crypto world in general, but the truth is that this world was looking pretty shaky even before the Terra disaster. Bitcoin, the original cryptocurrency, peaked last November and has since declined by more than 50 percent.
Here’s one way to think about that decline. Almost everyone is concerned about the rising cost of living; the Consumer Price Index — the cost of a representative basket of goods and services — has gone up about 4 percent over the past six months. But the cost of the same basket in Bitcoin has risen around 120 percent, which means inflation at an annualized rate of about 380 percent.
And other cryptocurrencies have performed far worse. Two cities — Miami and New York — have introduced their own cryptocurrencies, with enthusiastic support from their mayors. MiamiCoin is down more than 90 percent from its peak, and NewYorkCityCoin is down more than 80 percent.”
