They've made it apparent they don't like I would waste such money for the cost of the mining machines and pay for the monthly cost For running the machines.
Have you delved into the operational aspects of this business? They might be correct. Bitcoin mining operates within an intensely competitive market. It's significantly harder to generate profits compared to a few years ago.
If any of this makes any sense to anyone else, can someone share their thoughts on if maybe I sound like I'm being too stingy or unfair?
I'll be frank with you. I feel the same way, and yes, I may come across as a stingy Bitcoiner, but it's solely because I see its potential. My suggestion to you is to persuade or educate your partner about Bitcoin. It's challenging to maintain a harmonious relationship if one person recognizes the significance of DCA while the other fails to see its value.
Your primary focus should be your mental well-being. Now that you've grasped the concept of Bitcoin, you can't disregard it. It must either become a priority alongside your partner, or you may need to pursue separate paths.
