I get a flat rate for electricity here because my rent includes all the utility. So I was thinking of mining on my own to acquire more bitcoins. Is investing in a lot of money worth it to acquire some bitcoins? Also, how much money do I need to have to set up a decent mining system.
With the difficulty increasing and the block size to be halved again next year, in your position, I would really think about what you're getting into and use some ROI calculators and then think how much you really want to invest. Honestly, I started mining more to improve my understanding of crypto as a whole compared to just doing it for profit. In any case, I'd recommend that you rent some miners instead of buying, and if you do, mine some altcoins and hope they go up in value. Hope this helps.
