List of Altcoins grouped by category?

[ctcrnitv]

Where can I find a list of altcoins grouped by category / use case? For example, there are a handful of privacy coins, a handful of protocol coins, a group of payment coins, lending coins, and so on. It would really help me get a big picture picture view of the altcoins ecosystem, I'm surprised it's so challenging to find something like this. If there is nothing available so far, post your favorite group or suggestions and I'll curate a list here for everyone. I'll start with a few easy ones:

privacy coins:
monero
dash
zcash
pivx

You can find a list of altcoins grouped by categories/sectors on onchainfx. Here's the link - https://onchainfx.com/categories

Correct, there we can see according to category. Because there are so many types of cryptocurrency that exist in this world and sometimes we confuse to differentiate according to category.
