Large Memory Cache Issues

Hello linuxers,

I'm running a CentOS server (specs below) with 32 GB memory. My problem is 18.49 GB of the 32GB is used by cache. That seems to be a lot. Is that a good thing or cache is using too much? I'm running a cryptocurrency website. I cache a lot of stuff because I'm using API to pull cryptocurrency prices like the ones on this page: https://ift.tt/39IgzcU.

Is cache keeping the site from running out of memory or it's using too much and I should...
