### Rankings heuristics

The machine learning-genetic programming approach is applicable to both tokens and coins. Let us demonstrate step by step how it is applied to the BCT-BCH case.
Traffic share. We sample the top 1000 sources that are shared by both bitcoin and bitcoincash over a period of 6 months, from August 2017 to January 2018. To make the sources of attention representative, we select bitcoin.org and bitcoincash.org as the attention sinks. Figure 12 shows how the distributions are different: bitcoin captures the larger share of traffic from most sources (80% or higher), while bitcoincash has more sources that are small contributors (20% or lower).
