if i remember correctly those cpu are a bit worthless even for altcoin that are cpu only, and ram are useless for mining, better to use for something else
At this point they are. Most CPU altcoins can be mined with GPU so it blows them away.
There was a period CPU mining and VPS mining was profitable but now it's very very far from that. I remember having a lot of cores of processors during it at one point. But again it will not happen ever again in my opinion. VPS mining was one of the funnest types of mining there was. Was so fast paced and like a race on coins.
the last chance to use cpu mining with vps, was with cointellect, to abuse their solo earning, that was very high( 1.5 euro with just 300khs)
vps come in handy here because of the ip, so you was like spamming multiple account, with each one earning 1.5 euro a day, was a fun ride
