Have you studied Monero's RandomX algorithm?
It's designed in a specific way that favors CPUs (especially Ryzen ones), so that if someone wanted to design an equivalent ASIC chip, it would be as complex/expensive as a Ryzen processor.

X5, 212 kh/S, 1350W, at $3000, you get 1 kh/s for 6W and 1kh/s for $14
And in one scenario you got a ready to mine machine in the other you don't even get a fan....
1) Sold out (unlike Ryzen CPUs, even 7950X is readily available)
2) This doesn't use ASIC chips (unlike BTC or LTC), it uses RISC-V CPUs. Look it up.
RISC might be more efficient than CISC (x86), but it's still not an ASIC. You won't find a single RandomX ASIC.
You also won't see anyone using RISC-V CPUs for BTC or LTC mining.
