Yes the Ghostrider hashrate fluctuates because it does algorithm switching and some of the algorithms are more CPU intensive. The last time I did the numbers it came out to be more profitable than mining RandomX. Quite a bit of people use the miner but I'm not sure if they are members of this forum or if they came from discord. Putting out a new miner these days is tough all you can do is put it out there, be as transparent as possible, and wait. For the first few weeks no one used it at all and now it starting to get foot traffic.
