Well with ETH you don't know.

A month or 2 or 3?

Also

right now eth is paying 0.0704 cents a mh on viabtc

and they are giving 139% back on a block due to high fees.

so 101/139 x 0.0704 = 0.0511 cents an mh

translation for 3060ti

60 x 0.0704 = $4.22 a card per day
60 x 0.0511 = $3.06 a card per day

If eth price goes to 1800 due to the change it makes up for this.

So if you can get well priced 3060ti I say build.

even at 2 dollars a day for a card burning 135 watts 3.3 kwatts a day in power at 20 cents is 66 cent

so 2.00 - .66 = 1.34 profit. about 350 days to pay off a $469  3060ti
