Yes but the trade off is the frequency of blocks will increase with the higher hash rate and more people we get. It evens out.
So I was able to rent around 5-10 Th/s for about 12 hours yesterday. That upped the amount of shares I produced, which is what is important, right? Even if I were to rent for 6 hours... it's better than not renting at all because I'm producing more shares during that 6 hour time period and it won't be wasted. As opposed to renting 6 hours on Slush's Pool where if no block is found in that 6 hour period I wasted the rental. Do I have that correct?
