Hey guys! I'm a newbie considering starting my crypto mining operation. I don't feel like chasing the maximum short term profits by mining shitcoins with GPUs, I just want a stable long term operation so I think the best is to stick with BTC.

My budget is 60k$. Im comparing some SHA-256 devices (10x Antminer S19 Pro seems like a good fit at the moment) and by my very rough estimates, based on current prices, I should be breaking even within 18 - 24 months. Electricity cost from where I'm based is around 0.03$ - 0.06$ kWh.

So now we get to the question. I haven't followed mining profitability over time, so I'm curious how much does the profitability change over time? And how long until miners such as the S19 Pro become obsolete?

If you don't mind, please tell me how you would set up mining operation with 60k$ budget and 0.03-0.06$ kWh costs.

Thank you!
