This clause in the methodology provides us with future optionality. Given the current market structure, our expectation is that spot markets with transparent pricing will retain meaningful trading volume, and we will not have to select over-the-counter or derivatives markets. That being said, there is a non-zero chance that over-the-counter or derivatives markets may become more dominant (similar to gold in which the primary market is the London Bullion Market, an over-the-counter market), in which case the Coin Metrics Oversight Committee, after considering all available information, may determine that these markets serve as the best venues to derive index pricing from.
