Do not buy ASIC, you will never get your ROI (Return Of Investment).
Especially if it's not the latest hardware, anything older than "latest" is a worthless scrap that some people try selling like if it's worth something. It's not.

Big mining companies struggle to get their ROI and have been mining at a loss for some time - reason they are replacing ASIC's for HPC and switching to AI training.
Hint: it's not only the kWh cost! the whole infrastructure costs a lot of money to maintain.
You just destroyed your own argument!
Private small miners don't have to care about infrastructure as you don't need the same thing for a 30kw draw as for a 400MW farm, and everything is pretty scalable from scratch when you're a small two fans fan and one room would be enough, you won't have rent, you won't have maintenance guys, you won't have an accountant to care about and pay.
You have dirt cheap energy or even free one, you're better than the best farm by exactly buying and running scrap.
I thought it's a common knowledge and a logic thing to understand that big mining operations scale a lot better than small miners
I wrote about infrastructure costs just as a side note, small miners always overpay due to the fact that this big companies have better deals, earn a lot more with latest hardware and then sell it to idiots who still want to mine with this now outdated junk.
Of course, if you live in a third-world country where people starve and don't have water to clean their bottoms then sure, go ahead and buy it and mine with it on your unstable electric line.
Serious question: How old are you ? am I talking to a 13 year old kid ? what is this ?

If you still didn't get it, it's a rhetorical question.
