Crypto Wash Trading (arxiv.org)

Article summary

A study detected fake transactions on 29 cryptocurrency exchanges, revealing rampant manipulations on unregulated exchanges. The study found that wash trading, where investors simultaneously sell and buy the same financial assets, averaged over 70% of the reported volume on unregulated exchanges. This practice can distort prices, volume, and volatility, and reduce investors' confidence. The study also documented how fabricated volumes relate to exchange characteristics, market conditions, and regulation.

What commenters say

• Wash trading is a form of market manipulation where an investor buys and sells the same asset to create artificial activity, which can be used to inflate trade volume and distort prices.
• The practice of wash trading is more relevant to non-fungible assets like NFTs, where a single trade can create the illusion of a price increase.
• Exchanges may benefit from wash trading by increasing their trade volume and revenue, even if the trades are fake.
• Wash trading does not necessarily change the price of an asset, but rather increases the volume, making it appear more valuable.
• Some commenters believe that exchanges themselves may be engaging in wash trading to improve their rankings and attract more users.
• Others argue that wash trading is often done by third parties, who may be able to negotiate discounted fees with exchanges in exchange for high trade volumes.
• There is disagreement over whether wash trading can be used for legitimate purposes, such as tax loss harvesting, or if it is always a form of market manipulation.
• The lack of regulation in the cryptocurrency market makes it easier for wash trading to occur, and more difficult to detect and prevent.
