So I am pretty much brand new to mining, just using my Dell Inspiron 15 5000 laptop to mine while I am sleeping. My SO and my electricity is included in rent, my internet is $15 a month and our apartment is under $500 a month on the beach, obviously immediate return on investment would be crazy, but with the explosion of crypto I am certainly considering selling some to purchase a mining rig and play the long game in the market, but the question is how much would I need to drop to do a decent bite out of $500 rent?

Currently on Cudo Miner I am looking at an estimated 6061 satoshi, 1.05 kh/s but I am sure I could get a lot more with the 2 by 4 ft empty space I have next to my router. I guess the goal I would have for my rig would be ROI in 2 years. I also know nothing about building a rig so I guess advice on that or just purchasing the rig since I wouldn't have much time to build it before I would go commercial fishing anyways and it would be nice to have another form of passive income in the future.
