You do not have to do anything to make money only keep and hold your bitcoins.. Maybe you can join bounties and more but you can not make a lot of money.
This.
I found an old wallet from 2014. Means I was hodling the LTC in there for almost 4 years. Managed to find an old piece of paper with a password. At that time, I was a nOOb and had some wallet crashes, and gave up on LTC.
I had mined those coins with 2 x 7950 Radeons and a 7850.
Figured out the password.
Anybody that tells you cryptomining has no ROI is a total idiot and has no experience.
The best thing you can do is to keep doing it, and don't worry about the ROI. The money will come, eventually.
Good luck. I hereby give you some of my good luck.
