Thanks! We used a market cap based criteria when we published the first of these reports, identifying the three groups. We plan on rearranging those whenever a projects become too large or small for its group. It Is similar to what you have for stock markets when you have size criteria for admission to an index. The trick with cryptos is that the market is moving alltogether basically still, so you cannot fix a size treshold and you have to go with dynamic tresholds. You also need not to move groups components top much to preserve the coherence in the analyses. We still have same groups members of a month ago.
