Anya, takes out her calculator, says to herself now there is a proposition, 271 Ghs at .55 btc.  She furiously pushes a lot of buttons, inputs a lot of data. Stops, does some of the math in her head. Comes  up with about 26 weeks, possibly less. Decides, to offer .52 and bring it  down to 23 weeks.
            Then she sits back and wonders?   I've seen these people wanting to sell. Is this OK?  Ok with PB?  for someone  to want to sell  and transfer a contract,
      As a young lady and a student of math, I would maybe consider something like this offer, however is this ok  with PB, to do this , can I be safe with my  bitcoin?
    I would never want to do anything that might not be approved of by PB, And I would want to be sure the transaction was smooth.   Anya puts her calculator  away, decides to think about all this for a while.
       

Ok, so you did some math.  I would be curious to know more.

Are you taking past contracts and calculating how long they took to break even?  Are you then taking that data and extrapolating future break-even dates?  Are you assuming that difficulty increases will decrease or remain constant?  What is the average difficulty increase that you predict over the next 30 weeks?  These details would go a long way in helping me understand how you arrived at your opinion.

       Anya, - All good and intelligent questions to ask Netwerked, you deserve an answer. Yes I am doing all that you mention above. I bought contracts each week and each difficulty period and and from these I'm extrapolating future data. Difficulty has never remained constant or dropped in this time period we are considering. Therefore I am adding a substantial difficulty for each two week period.  As for what the difficulty will be for the next 30 weeks, its going to be increasing but not the huge jumps like we saw a few times when huge mining farms came on line. We will see the small jumps like we saw a few weeks ago, this next one is also slightly smaller than some we have seen.

Have you actually plugged this in to a spreadsheet, or are you telling us what your intuition is guessing?

Yes, February contracts broke even in July, and I don't doubt that April contracts have broken even or are breaking even now.

This does not automatically mean that all future contracts will break even.  Past performance is no guarantee

For a mining contract to be profitable, you have to receive more mining income than the purchase price of the contract.  While the cost/GH of contracts has fallen significantly since February, so has the weekly mining income from each GH.

This calendar year, difficulty has risen around 16% on average.  If someone purchased a contract at the beginning of August, and difficulty continues to rise 16% each time, then they will never break even.  This is part of the risk we take with Bitcoin mining.  Hopefully we will have some more single digit difficulty increases in the near future to increase our odds for profitability.

   Anya            I agree with some that you say. Some dosen't add up.  Future contracts will break even, it is a mater of how many weeks.  Again, this word (never)  is problematic.  I dont want to discuss spread sheets and such, 
       August contracts will break even. but the amount of weeks to achieve this is rising.
 If you bought in August, your looking at 30 to about 32 weeks, a ten or twelve week jump from buying in April. I predicted the April breakeven long before it happened, i know that even if my math is way off, say it 35 weeks to break even from August,  I then am way more accurate  in my calculations than what I hearing out here.  (never)
No that doesn't add up. 
       Profit, that a whole different thing,  I loved being part of the birth of bitcoin, I love how people were actually mining at home, creating a new future  in trade for us.
Pb gave me the chance to have the fun of mining with out being complicated.  I love the math involved with it all. I wipe a tear from my eye that the glory days of mining is over,  We are now approaching the commercial stage of bitcoin mining.   Therefore, no I'm not saying there going to be much profitablity,  I am saying that that contracts bought through August will reach breakeven, it not a matter of if , or never,  They will in 32 weeks. 

[quote author=PBmining link=topic=  Our business model is pure awesome and so we will continue to run things the way we have been.   

     Anya Thanks you for this. One of my enjoyments of life is waking up each Sunday morning, making my coffee and sitting down to enjoy my Mining payment.

Hi, can we hear from the winner and have information on the results of the contest?

It's a good Morning! Three contracts reached breakeven, and are into profit.  Twenty one payments, Thanks PB.

It is  bothersome that someone can not state their opinion with out someone calling them a plant. I am not a plant, I am mining on PB just like everyone else. Some of you have your terms mixed up also. R.O.I. means return on investment. Spouting off that your never going to reach R.O.I. is foolish. Your going to reach R.O.I. each Sunday no matter what. Breakeven  is when you got back the BTC that you paid for your contract. That is also going to be reached, most likely in near 26 weeks if you bought in June or July. If you live to this Sunday you will reach R.O.I.  Waiting 26 weeks more or less you will reach breakeven eventually.  I am not a plant, customer #6606.

Hi  My name is Anya, I'm a student of math and science. I've been reading many things here that don't add up and tend to be wild speculation with calculators which is producing inaccurate information.  I think we all agree bitcoin mining has seen better days, difficulty has soared, and mining going to be pretty difficult from here on. That being said, it is possible that any home or cloud mining might not be such a great thing to do in the future. What I disagree with here, is we have people saying these contracts will never reach break even or turn a profit. That just is not true. Math shows me, that all contracts bought in March have already broke even and are into profit. I have three contracts bought April 6 and 7th , next week they will reach break even on their 21 week.  In the weeks after that I have other contracts bought later in April and May, My Math shows me they will also break even, although some of them depending on where I bought them in the difficulty cycle ,may take a predicted 22 weeks.  Those are the facts, not speculation.   I also bought contracts each month and bought two in August.  Do I expect that in 21 weeks these will break even?  NO. I am predicting a 24 to 26 week break even for these. One last thought, I was involved with many investments in the past. I was a rocky road  filled with potholes. Sometimes I lost my investment, other times I was lucky to get 75% of it back, sometimes things worked out very well. When you look at your PB mining investment, think about it in terms of how many weeks will it take to break even. I see newcomers in here who act like they expect to be into profit after they been into this for two weeks. With any investment if in 5 or six months you have broken even and still have 4.5 years to go of weekly rewards, I would say your doing pretty good. Yes difficulty is quite steep, maybe the profits will be small, but still it is a profit and will continue for a long time. I'm a girl so please be polite.

I think buying and holding is a good thing to do, however I don't believe that buying contracts with PB can't be both fun and profitable. I started small back on April 6, buying small amounts 25 or 30 and as weeks went on buying larger amounts 50 and a hundred and then eventually contracts of hundreds. I now own 2,000 GHS and plan on increasing more soon. The way this works out is after 22 weeks the first contracts I bought in April will have paid me back what I have paid for them. This includes all the difficulty increases as well as near future difficulty increases. I'm having a lot of fun, I am being paid more than a third of a bitcoin per week. The past eight weeks I have averaged a payment each Sunday of about $230.00 dollars. So when I read some of the post in here saying don't invest in this because you will never get your money back.
Simple math shows me that if you wait 22 weeks, you will receive back what you have paid in, worse case possible, lets say it took 26 weeks which is exactly half a year. Then even with a miserable difficulty I will still be receiving a payment each week. It may be smaller but then again bitcoin might also be much more valuable than it is right now. using my math, I am willing to bet that all of the people who bought back in March are now seeing break even on what they paid for those contracts. Another aspect of this for me is, I bought much of the bitcoin that I purchased these contracts with when it was in the 400 dollar price range, and now it's paying me back when bitcoin is in the 600 dollar range. That's my take on this, sorry it so long. 

Hi, I notice the PB Android app isn't worked since yesterday. Anyone know about this?
