Since you aren't in any form of hurry then it can work, you will need alot of patience because in coming months crypto market can decline alot making every dream not worth it anymore, think about this very well before doing it and also make sure your electricity bill is nearly free ( cheaper ) just for the sake of continuous mining in bear market period
cheap power and good card deals do the trick.
all my 1080ti evga hybrids ran from 2017 to 2021 I sold all of them in Jan of 2021 for close to list price of 2017. my partner and I had 28 of them. not a 1 failed. well a fans on the radiator needed replacement but that is nothing.
So they all paid off fully more then once and were sold close to original price in 2021.
needless to say we did well.
we have a lot of gear again. but we have cheap power and do no run the gear hard.
