It has been a while since we last covered the cpuminer-opt software, but the good news is that its development hasn’t stopped and this should probably be your go to miner as far as CPU mineable crypto coins are concerned. Do note that cpuminer-opt is an open source mining software for processor mining that supports a lot of algorithms and that list is growing, though you will most likely be using just a couple of them nowadays. The miner has optimizations for older and newer AMD and Intel processors, so make sure you try the binary that is intended for your processor for best results or feel free to experiment.
The alternative that often comes handy as far as CPU mining is concerned is SRBMiner-MULTI that supports fewer CPU mining algorithms, but some of them could be more optimized compared to cpuminer-opt, and also has support for RandomX algorithms (mostly targeted at AMD Ryzen CPU miners). SRBMiner-MULTI however is also a closed source miner with a built-in developer fee, even if it is a verified and a trusted one, some people still prefer to use open source mining software only s far as crypto and not only is concerned.
Have in mind that cpuminer-opt is available as a pre-built and ready to be used binary only for Windows, it has its source code available for everyone, has no developer fees of any kind and is supported only with donations, so if you find it useful fee free to toss some coins to your friendly software developer JayDDee (joblo) on Bitcointalk to the following Bitcoin address: 12tdvfF7KmAsihBXQXynT6E6th2c2pByTT.
