I'm mining RandomX coins with free miner xmr-stak-rx(0% dev fee). I mine 2 coins at a time one week I mine Monero and Another week I mine Loki. The shitcoins are the ones which are young and have low-market cap right now, they might not much profitable as compare to current price but they are profitable in the long-term.
It turns out that even shitcoins can prove to be good in the future. I understood you.
I'll try to look for suitable coins on exchanges. Thanks!
