When you're buying mining equipment, make sure you compare price per GH/s (remember to add power supply, if not included), electricity usage, etc.
There are some very bad deals out there, which can never break even. Whether you pay $10 per GH/s or less than $1 per GH/s is important.
It's just the last 1.5 weeks that have been crap.
Last 10 days we found 19 blocks, so 1.9 blocks per day. The average we can expect with our hashrate currently is 1.6 blocks per day. I wouldn't call 1.9 "crap". Or 1.72 blocks per day the last 11 days, which is still good. Depending on whether 1.5 weeks is 10 or 11 days.
Try not to focus only on the unlucky rounds. It will make you think you are having bad luck when you're actually being lucky.
Which means the next 1.5 weeks should be pretty good in theory
No, past luck has no impact on future luck. Thinking so is called "gambler's fallacy", which you can read about on Wikipedia.
Every time you play the lottery or roll the dice your chance of winning is the same. It doesn't matter whether you won or lost the previous time(s).
The graph you put up clearly shows an oscillation, that then translates into an average. From my view we had that 3 day block, then a day with like 4 in one day ( glorious ), and then after that we have 1 block per day for the next 4 days. Then 2 so far today. In 9 days we picked up 10 blocks. Which is below the 10.9 per week quoted by someone a few posts back.
Following the cycle so far ( not gambling in the true sense ) that would suggest we now have a few days of good times coming.
Which naturally means I have just jinxed it
Hence why I advise to think monthly. Good weeks happen, bad weeks happen, and it's what it adds up to at the end of the month that counts ( as in, can you pay your electricity or not ).
This pool does appear to perform well. You just have to allow for the odd duff week, as life is life.
I chose to pick up an S3 to add to my Coindesk unit. My Coindesk is running at 700 GH/s for 770w at present, and can be dialed back to 530 GH/s for 500w later in it's lifetime ( as difficulty rises ).
The s3 is brand spanking new, so based on that I should get maximum profit on a 1.1 GH/s per watt unit. Not sure if I'll be able to pencil-mod it later in it's life, but I would assume it's the same as the S1 here.
