Bitmain Antminer KS5 Pro. The state of the art mining rig today, pumps out 21TH of hashrate. You can buy one to receive this month for 30k, or wait until august and get it for a cheap 11k$.

21TH, will make you 1$/day.

That's 27 years for ROI (obviously not because of difficulty and price changes, but let's assume.)

Say you buy 20 of these bad boys.

This is going to set you back 220,000$. For a hashrate of 420 THs.

It will take you 500 days, to be able to accumulate 11k, to add one more miner to your farm.

Remember I am completely disregarding any electricity costs here, just to realize how absurd it all is.

Is there any conceivable scenario, where buying a bitcoin miner today, is more financially profitable than just buying bitcoin?

I think from Genesis it was more expensive to buy a miner and mine bitcoin compared to simply buy bitcoin.

Even when you could cpu mine bitcoin, you still need to buy the pc, and even assuming the hardware was free, the electricity was higher than the price, which was $0 for a couple of years or so.

I think the benefits of mining are simply that someone will do it, so might as well be you. But you have to be able to do this for the long term, otherwise you won't be able to survive and pay the bills today.

Also, you can see this as a lottery ticket as well, for solo mining. Much cheaper than paying multiple lotto tickets.

the op is talking about the wrong miner. a ks5 has nothing to do with mining btc

the t21 burns 84 kwatts a day.

if you pay 10 cents it costs $8.40

it earns $11.40 a $3 a day profit for 10 cent power cost.

but if you pay 15 cents it costs $12.60 that is a $1.20 loss

so

10 cent power = $3.00 profit
15 cent power = $1.20 loss
