A cryptocurrency trader seems to have stumbled upon the industry's little secret.
Finance Magnates
An investigation has revealed that more than 3 billion USD of the daily volume of some major cryptocurrency exchanges is entirely fictitious.
The dramatic piece was written by cryptocurrency trader Sylvain Ribes and published in Medium. He identifies the biggest culprit as OKex, which is currently ranked as the biggest exchange in the world on coinmarketcap.com, with daily trading volumes displayed as more than 1.5 billion USD.
Ribes wrote: "It is an absolute disgrace that CoinMarketCap and LiveCoinWatch should list these scamholes alongside sometimes struggling legit exchanges."
Slippage is a term common amongst foreign exchange traders - it means the difference between the price of an asset at a given moment and the price that you actually pay for it. The difference occurs because the market can change in the time that it takes to request, process and execute an order. Imagine that you go to an electronics shop to buy the latest boom-box radio set to impress your friends. On the shelf, the set costs 15 euros, and you pick it up and carry it to the till. Once you get there however you are informed that the price is now 16 euros, because the market changed in the time that it took you to walk from the shelf to the till. If you were to decide that you no longer wanted the boom-box radio set, and returned it to the shelf, you could well find that the price has risen still more, or even dropped to below 15 euros.
The following chart displays volume as a function of slippage for a number of cryptocurrency exchanges. OKex is marked in green:

One doesn't need to particularly understand what slippage is to see that there is a conspicuous outlier in this chart. Ribes calculates that OKex's volumes are, at a conservative estimate, 92.9 percent fabricated. This dramatic claim is supported by another suspicious-looking image:
Source: Medium
Again, no expertise is needed to understand that the sine wave pattern seen at the bottom of the above image most likely does not represent the organic movement of a currency market - Ribes calls it "laughingly obvious and artificial".
Using the same methodology, Ribes found that Huobi, another Chinese exchange, invented 81.8% of its trading volumes. The author also had some issues with Binance, but was careful to note that he did not find any suspicious activity regarding its claimed volumes.
It should be noted that Ribes lists caveats to his research such as data volatility, time examined, variance, hidden orders - that is, variables that he did not take into account. He does not claim that his investigation is exhaustive, but does say that it is undeniable that something fishy is going on.
If his assertions are true, traders should be worried. The cryptocurrency market is not characterised by its stability at the best of times, and evidence of large-scale manipulation is unlikely to improve matters.
