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?

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.
