What should the price of a terahash be

What's your take on how much 1TH should run for? After factoring in electricity, what's the best price you'd consider for 1TH? I get that electricity costs are key, but what's a solid price-per-hashrate deal for you?

I've never done such calculations. I was more interested in the final profit, because you'll always have additional expenses. If your electricity costs 2 cents, you can use even the very first 19-series ASICs at 90 TH and you'll always make a profit. I think the main thing is to buy an ASIC that won't cause you problems with repairs and breakdowns.

You're not actually buying terahash, you're buying watts dressed up as terahash. And yeah, saying "if you have 2 cents power you'll always profit" is optimistic. Low power does help a ton, but difficulty climbs, price dumps, machines die, and all sorts of other disasters can occur. I'd prioritize efficiency and reliability first, then think about $/TH.

I know that most shadow miners choose cheaper equipment and places with lower electricity prices.

It looks like you are planning to buy terahash from some sellers on miningrigrentals? I think it depends on the unit power efficiency, like the sample. I think the S19 XP could draw 22watts per 1 terahash. Without the electricity fee, you could make $0.0383 per 1 terahash with the current difficulty. That should be the cost per day with 1Th.

If I sold him hash with my t21  I would want 10-15% over what it can hash I can give him 180th it earns 180 x 3.92 cents or 180x0.0392= $7.056   I would charge $8 or 8/180=0.0444 so yeah 4.44 cents a th would be my charge. 0.0392x1.13=0.044296 it is a 13% markup and that's fair because he never purchased the gear. so my markup is for the gear I own and the labor to program it for him. here are the 2 units 61th and 121th

Reasonably aim somewhere to 9 TH including shipping for BTC mining. And for electricity in USA you have quite good deals in Texas - but it is quite hot there. Or you can try hosted services where they have already good deals and lower electricity. So up to 9 USD . Like S21 200TH we get now for about 8 USD per TH including shipping and declaration and in USA. We locked about 400 pieces -- the last in the market Just I prefer to go with less expensive machines and pay little bit more for infrastructure to have cheaper electricity.

How much do you pay for electricity? My calculator shows that at 7-8 cents per kilowatt, this equipment is almost unprofitable. Cheap electricity offers many more advantages than the price of 1 terahash of equipment. The cheapest and most relevant are the 6th and 7th generation ASICs. The 9th generation is the most modern and expensive.
