Sell-offs in the market for cryptocurrencies like bitcoin and ethereum continued this week. The rout followed another shock in May, when the value of terraUSD, a popular “stablecoin,” crashed.

Stablecoins are supposed to have stable value tied to the U.S. dollar, which is why crypto traders use them to move money around this volatile market.

But when terraUSD crashed, it wasn’t just traders who were hurt. Thousands of small investors were caught up in the meltdown, including people who put their money in Stablegains — a now-defunct crypto savings account company that promised returns of up to 15%.

Marketplace’s Matt Levin recently spoke to some of those people. He explains that they’re not the typical crypto investors you might think of and why they put their money into crypto in the first place.
