Good stuff! Have you seen this periodic elemetn table of cryptos - its pretty cool!

I've found that assigning categories is quite hard, mainly due to the 'other' category. Once you go and look deeper into say top 1000 cryptos, you realize the need for many subcategories, due to the number of niches that blockchain is now applicable to. In addition, many crypto projects have multiple use cases, and therefore can be categorized under a few different tags.
