i recently got lifetime vps with 8gb ram and 8 cpu cores. is there any altcoins to mine that will be profitable and would there be any problem mining on vps. Thanks in advance. I am newbie here, sorry if i happened to post in wrong section or something. 
You can look at some altcoins such as monero, xzc, xdn . these altcoins only use cpu mining. it's very useful for you.
