When I was mining circa 2017 - 2021 (approx. 1 BTC/month and 25-30 ETH/month) and planning it all out, I prepared myself psychologically to operate for up to 2 years without any profits or selling. It was a hard pill to swallow and a huge risk; my costs were $8500/month in electrical and then another ~$2200 on a lease for the warehouse. When it dropped to $3,000/BTC a few months after I came online and stayed there for 6-8 months, I started wondering if I was the biggest dumbass in my county.

Thankfully, it all worked out in the end very well. I don't know how anyone would put in the effort/money to get a major crypto farm going and plan to just cash out every month to pay bills. What's the point? I always thought of it as a long-term bet on the price going way up, which it did.
