lets say going rate is 0.0105 a th and you get 0.0102 a th you rent 100th which is 1.02btc which is .03 under the going rate. to do this alone is very hard and it just means you rented at a discount.
You pick a pool and hash and the pool sucks make hardly any blocks = you get fucked and lose. even though you paid a good rate.
In this case I paid a very good rate and the pool whaled = the best of both worlds.
Kano's pool is the best ppns pool to do this because the 500% gives more days of hashing having earnings which tend to flatten the risk out a bit.
here is what is left of my earning power. I ended on a high rental this keeps the avg up I was
100-100-100-100-10-10-10-10-10-10-10-10-10-80 more 10's-200 I am left with some of the 10 rentals and the 200 at the end my avg is down to 4.84th
4.84/1800 = 0.00268889
0.00268889 x 25 = 0.067 btc if we hit a block and that will decline.
the key to renting get a good price. High---low---high.
I did 100 then 10 then 200
My rental was simpler: 100TH (from WestHash.com) pointed at CKPool in the wee hours of Wednesday morning, the 29th, at like 1 or 2am.
Cost me 1 BTC to run that for about 21 or 22 hours, basically all day Wednesday.
I've gotten .162 BTC on every block since then, so far 8 of them. Which brings my total payouts from CKpool to about 1.35 btc ...and counting!
But don't hate me yet. My last bet before that, also 100th for 21hrs for 1 BTC, paid just a fraction on two blocks that were solved just as my hash power came online, after which this pool saw a run of bad pool luck like I have never seen, and didnt crack a block for like a week.
I do love the 500% pplns because long after I'd thought it was over, I did still get paid a little more, on the two blocks that hit after that long run of nothing. But, all told, that 1BTC bet barely paid me back .5 btc
So yeah -- pool luck can be a cruel mistress!
