Monero is really where it's at, it's stable, has a low transaction fee, easy enough to mine via cpu and/or gpu. The great thing about monero is that you can run it via browser so you can monitize your webpage with no ads showing. The only downside is most people don't configure it to only use a specific % of the cpu, so people start freaking out that pages are doing 100% of their cpu. if i knew more about setting up the website to only use say 25% cpu, i'd run it on all my sites. Right now i can only seem to get it to do 100% and that's simply not good. Monero doesn't do great hash when you use "threads" you simply want to use "cores". So when the web browser miner starts it uses every thread it can and tanks the hash rate. but that's true with all crypto cpu mining.
