Cryptocurrency Exchanges : Predicting Which Markets Will Remain Active

About 99 percent of cryptocurrency trades occur on organised exchanges and many investors subsequently keep their digital assets in accounts with cryptocurrency markets. This generates exposure to the risk of exchange closures. We construct a database containing eight key characteristics on 238 cryptocurrency exchanges and employ machine learning techniques to predict whether a cryptocurrency market will remain active or whether it will go out of business. Both in-sample and out-of-sample measures of forecasting performance are computed and ranked for four popular machine learning algorithms. While all four models produce satisfactory classification accuracy, our best model is a random forest classifier. It reaches accuracy of 90.4 percent on training data and 86.1 percent on test data. From the list of predictors we find that exchange lifetime, transacted volume and cyber security measures such as security audit, cold storage and bug bounty programs rank high in terms of feature importance across multiple algorithms. On the other hand, whether an exchange has previously experienced a security breach does not rank highly according to its contribution to classification accuracy
