You don't really need to worry about it being unprofitable ASIC mining unless you have old hardware.

Sounds like nonsense to me. Now I'm wishing I had made this thread self-moderated.

Please check out whattomine and plug in your numbers to see what you'd earn.

Thank you for uselessly repeating what has already been said by two other people in this thread.

Here is the thing. You don't want to go off of just "amp pull". You want to look at profit and how you want to leverage it.

The other thing is, profit per amp is important, because once you get bit by the mining bug, you may want to buy another.

Right now, I'm looking for a garage heater that earns a bit of Bitcoin to offset it's costs a bit. If it does a good job of keeping the garage above o degrees celsius throughout the winter, then I'll probably become more interested in helping friends and family do the same than in taking up mining for myself at any scale. Mining for any significant profit is an arms race that has never interested me, and most of the time it seems like I can get a better return purchasing bitcoin than purchasing mining equipment.

You may be right, I might change my mind once I get started, but for now I can only plan based on what I know about myself.

So take watt / volt (240) = amps.

Thanks, I'm already aware of the relationship between amps, watts, and volts (as well as the many other units of power, work, energy, potential, current, resistance, etc).

My most protifable miner right now is mid pack on the amp pull, so I actually bought another one last week.

At the moment, I think I'm probably more interested in the most effective heater. However, there are a few other variables to consider...
If two different pieces of equipment each emit roughly the same amount of heat and one of them costs significantly more to purchase (or to run), then the cheaper one is preferred.
It two different pieces of equipment each emit roughly the same amount of heat and one generates significantly more revenue, then the higher revenue is preferred.

Obviously those variable play against each other quite a bit. It's likely that I'll find that one unit costs more to purchase but ALSO generates more revenue. What I'm trying to figure out is how to balance those competing incentives.

You will find your house to be amp constrained really really fast.

Just to heat the unheeateed spaces? I doubt it.

just raise the garage door and put a box fan behind it. I live in Texas, the garage is 99 degrees so I flush out the heat (but I am moving to immersion cooling).

None of that sounds appealing to me.

If it gets "too hot" then just unplug it for a few months and come back!

Yep, it will probably remain unplugged from March through October. It's possible I might decide to leave it running until mid-May.

The main problem with any calculation is it will be wrong tomorrow.

The result of the calculation is constantly changing, but the formula should be consistent. If I can get the formula correct, then I can write some software to gather the inputs and text me when the result crosses a threshold. That way I'll know when to run it and when not to. However, now that I've come to the realization that I'll still want to run it even when it isn't profitable (since what I'm really looking for is a heated that simply offsets its operating costs a bit), the calculation that I initially asked about is no longer so important. Far more important is getting enough heat for a reasonable initial purchase price, and maximizing the revenue for a given amount of heat.

The price varies every day and the difficulty varies every 2 weeks.

I'm well aware of how often the bitcoin exchange rate and the difficulty change. Initially, I thought I wanted to take that into consideration, but I now realize that neither of those really matter for this purpose.

The biggest winners this year are those mining last year with new equipment back then, that didn't switch off and sell their hardware due to such calculations.

I'm not looking to "win" any contest. I just want to heat my garage, but I'd like my space heater to earn as much bitcoin as it can.

The main point would be to not pay ridiculous high prices for miners,

This is what I have no experience with. I'm moving into this process slowly and carefully to try to avoid overpaying and avoid getting scammed.
