As I previously read I think you mining with only 100ghs correct? May I ask why? Also where are you located? I may have a deal for you if you are in the us. To get you a little more ghs. if you are in the US leave your zipcode and I will post my offer for you here.
Unfortunately, I am not living in the US. As I have put into my profile on this forum, I am living in Vienna, Austria. I have only 3 Antminer U3 miners but only 2 of them actively mining on public pool servers. So yes, practically I only use about 100 Gh/s hashrate for trying the pools. I am using the other miner for testing and learning about the miner software and pool server software on my spare time.
As to why I have only that much of hashrates, I am just a hobbyist miner and I don't want to put too much investment on this. I can definitely buy Antminer S7 for instance, but I still don't think I would make profit in short period of time due to the cost of the electricity. And there is no space in my apartment to put big mining rigs. I also tried renting the hashrates but I practically didn't make anything out of it even I have mined on Antpool which always find a new block at least every hour.
You wont make anything off renting unless the renting price is lower than the reward per block. So take my hash rate 3 s3's around 1400 give or take a few ghs I make rough .009 to .01 supposedly from eligius. I only say supposedly because it depends on if they find any blocks. For me to make that mark they would need to find on average 3 blocks per day.
So let see what it will cost with nicehash.
On Nicehash to get the same speed for 24 hours I would need to purchase 1.5 ths at .0070 have a balance of .0105 to get 1.5 ths for 24 hrs. But this is only if you use the fixed rate. If I didn't use the fixed rate and the cost of rentals went up I would loose time on my clock fast and not receive the full 34 hours I need to get the same rate as I needed to achieve the same result on eligius.
Now this is still based off if the pool found only three blocks in one day. Lets say they found more with in the 24 hours. Say they had a good day and found 5 block within the 24 hrs. That could give me a balance of 0.0156417 if the pools hash rate stayed the same the entire 24 hours. If the pool hash rate increased, my reward would decrease if the pools hash rate decrease my reward would increase. So it is all a gamble, If they found 5 blocks even with a little flux in hash rat ether way. I would still make money on my renting only by .005145.
But lets they pool had a bad day and only found two blocks. Since my reward at current pool hash rate is .00312834 per block I would only make 0.00625668. And this would be a loss on the rental.
But this example is apply this this type of pool though. If you say rented hash towards a pool like kano's and they same amount of blocks where found on a good day and bad the payout would be completely different because his pool has a ramp up and ramp down rate meaning you wouldn't receive a full payout on the first or second block until you ramp rate was to full speed and then once the renting was over you would have a ramp down rate that would still be running even after the renting was completed. meaning you would still be getting paid even after you renting was complete as long as the pool was still finding blocks.
If say Kano's pool was finding block left and right during your renting you could end of make huge money off your renting. Well no huge but I have rented in the past and spent .2 over a course of a week at kano's and made .05 off my renting trial period I tried. But this was only due to the fact the pool had good luck during my renting stent. If the pol would have had back luck I would have been in the black.
So you see you can make money off renting you just need to play the market. Rent while it is low and not when it is high. and hope the pool your mining with has good luck.
And sorry I was going offer you a free S1 I have sitting here collecting dust if you wanted to pay the shipping on it. But the cost of shipping over to Vienna, Austria even at snail mail would still not give you a reward for a very long time if any, if it where to break at some point in time.
