What should I do with an old profit sharing account?

Context: I’m a 30 year old male. A recently got back into a profit sharing account from a previous job. I am sitting on $36,540.

Is it okay to leave the money there even if I am not employed with the company anymore? It looks like I had 18% growth YTD.

I am not sure if I should be leaving that be to continue to grow, or if the money would be better off being moved elsewhere?

If I should move it, should I look into opening a Roth IRA or some other type of account?
