  • NPR.

  • The cryptocurrency market has been especially frothy in recent months.

  • According to CoinDesk, trading activity on crypto exchanges clocked in at $9.7 trillion last month.

  • To put how much that is in perspective,

  • that makes it the busiest month for crypto trading this year and almost twice as busy as the same time last year.

  • But what if a lot of this trading activity is an illusion?

  • And what if it's really a smoke screen for fraud?

  • This is The Indicator for Planet Money.

  • I'm Adrian Ma.

  • And I'm Waylon Wong.

  • A few years ago, we did an episode on an emerging practice in the crypto market called wash trading.

  • Today on the show,

  • we'll look at how the practice is evolving and what regulators are doing about it.

  • Most crypto trading happens on platforms that are unregulated by government watchdogs.

  • And according to a 2023 study done by researchers in the UK, US, and China,

  • about 70% of trading that happens on these unregulated platforms is actually wash trading.

  • Leah Foley is US attorney for the district of Massachusetts,

  • and she explains wash trading like this.

  • Wash trading occurs when a single trader or a number of traders working in coordination buy and sell the same asset to generate misleading market information.

  • All right.
