So, I’m comparing gpus on cryptocompare. If I look at a cards hash rate, and its profitability... if you’re going to buy say 8 cards...

Does it stand to reason that because your one cards hash rate becomes exponential dependent of # of cards, than your days to profitability would also be exponentially as well? But going in the opposite direction?

Card X gets an annual return of $10k 8 * card x = $80k

If one card X profitability is 256 days, would 8 cards be 256/8? Or would you just aggregate them all as a combined expense, and then compare the cumulative hash rate against the machine costs to calculate yearly profit minus expenses?

Would it be:

80k - entire machine cost = yearly profit?

If that is the case, would New machines exponentially impact profits? I’m trying to see how this could scale to maybe make a large scale mining operation and calculate 5 years of potential profit.

Thanks in advance!!
