Coinevo (EVO) is another crypto project forked from Monero that is based on the RandomX algorithm, though using its own variation called RandomEVO that you might be interested in checking out if you have some spare CPU power to throw at mining something relatively new. Do note that although EVO is a PoW coin it apparently also supports Masternodes and about 2/3 of the block reward goes to the nodes and 1/3 to the miner. You need to use a dedicated fork of XMRig (XMRig-EVO) in order to mine Coinevo as the specific algorithm is not widely supported as some of the other variants of RandomX.
There is an official EVO mining pool as well as another alternative EVO mining pool with more hashrate available, though the majority of the hashrate seems to be from solo mining apparently (in general not a lot of hashrate). There is an exchange called EREX, a very low volume crypto exchange not much EVO trading going on. Performance wise the RandomEVO algorithm is doing better on AMD Ryzen than on Intel CPUs, here is a comparison of what hashrate you can expect to see: about 2850 H/s on Intel Core i7 6850K (6C-12T) and about 9800 H/s on AMD Ryzen 3900X (12C-24T).
