Artificially Inflated Volume On Large Crypto Exchanges

Up to 98% of Ethereum (ETH) trade volume on large crypto exchanges is artificially inflated. The results were published in a paper by Blockchain Research Lab. But which exchanges are trustworthy?

Analysis of trades turned up surprising amounts of so-called “wash trading.” Wash trading occurs when trades do not materially move the net value of an asset but do inflate its trading volume.

The paper places exchanges into three groups: ones with honest volume, ones with possibly inflated volume, and ones with clear evidence of inflated volume.

Larger trade volumes rank exchanges higher on the list for sites like CoinGecko and CoinMarketCap. The higher rank brings in more traffic. CoinMarketCap uses its own algorithm to address the validity and reliability of posted trade volumes and liquidity.

Some exchanges could have bad actors posting fake orders on their books. If these accounts are indeed owned by the exchange, they increase liquidity and depth artificially.

A Who’s Who of Who Lies

The first category researchers determined were the honest exchanges. These included Bitfinex, Bistamp, Bittrex, Kraken, and Poloniex.

The second category, the ones with inconclusive evidence, were the giants Binance and HitBC, as well as the smaller, less-established exchanges like KuCoin and YoBit.

The third category, the ones with obviously inflated trade volume, included FCoin, Huobi, and OKEx. The researches used data from the honest group to scrutinize the exchanges with fraudulent volumes.

Blockchain Research Lab relied on indicators, such as posted trade volume, balances on the exchanges, the number of wallets, and web-traffic to determine how much volume originated from wash trading. They used trade volumes for BTC, ETH, XRP, USDT, and USD to make their determinations.

The average daily volume for BTC/USD for exchanges from the first “honest” group was about $42 million. The second group accounted for a much larger $170 million, and the manipulated exchanges claimed a volume of almost $490 million.

The ratio of trade volume to actual page views in the third group was 138 times that of the first. Likewise, the ratio of ETH trade volume to the balances on the exchanges was much higher in the latter two groups than the first.

Based on this data, analysts proposed a theoretical trade volume for the second two groups. This theoretical trading volume was 50% lower than the “official” trading volume claimed by the exchanges.

The researches also inferred that 96-98% of ETH trade volume on exchanges accused of falsifying results was suspect. Analysis of token balances compared to trade volume also suggested that 72-97% of the volume could have been falsified.
