Thanks for the reply.
Well I tried this already, but gave it another shot with a different asic. and sure enough the Green light finally came on (no red light either!)
BUT.. Still cannot see it on the network. Soo not sure where to go from here.
Well that is a good sign. I would now try reseting it via the button with that bad ASIC unplugged. That fixed it for me when I had the same issue. |

Talk to CrazyGuy. He probably has some available.
Alright I will find him and see what he has. Do you know if the newer Prisma are more stable than the last ones? I have read a lot of mixed opinions on them. I recently have ditched mining Scrypt so I am now getting back into SHA256. |

It is not hard to believe that China mines so much of the coins since they produce most of the miners. I would imagine that the cost savings on shipping alone makes a huge difference.

I was looking to purchase one of these Prisma 2.0 miners since I had good luck with the cubes. Does anyone know if these are still currently for sale or if they are even worth it?

I had a similar issue and it turned out to be a bad ASIC board. Try booting it with only one ASIC board attached and see if it responds. If it does respond then add a second etc..

Do they offer us a discount if we purchase multiple units? Has anyone attempted a group purchase of these miners to drive the prices down?

My guess is 2.26 - 2.50
Hopefully my luck will be better this time around
edit: this is +2.26-2.50
(+2.26) to (+2.50) correct? Please use that --- to ---- makes it easy to read Yes sorry. My guess is +2.26 to +2.50 percent (an increase). Sorry for the confusion |

What is going on in the bitcoin mining world that is having these awful swings in block time?
This is just variance. It doesn't have anything to do with the fact that difficulty is 'too high'. Even if the difficulty 'matched' the hashrate perfectly (it never will because of changes in the network's luck) then it would sometimes take 41 minutes (or longer) for the network to find a block. The 10 minute block time is only a target average |

From the looks of it I have received my last signature payment from GAW miners (via EvilPanda). It has been quite a journey and it is sad that it has to come to an end. I wish you the best of luck and hopefully you will find another signature campaign to manage in the near future  |

I did read throught supportment site and articles and he really got arrested for trading btc without licence that isn't even needed? WTF?!
He was indicted for transmitting money without a license to someone who was planning on using the proceeds of the transmission for criminal purposes. In other words he sold bitcoin to someone who was said he was planning on using it for something illegal. |

What everyone (except one person) fails to realize in this thread is that different miners will consume different amounts of electricity per TH/s then can do. As a general rule, newer models (based on when they were initially released) tend to be more efficient then older models. Since a cloud mining company would need to be constantly buying newer hardware their average age (and efficiency) of their farm is going to be worse then what you can buy with the latest and greatest
please put some links with the latest hardware and let's make some calculations after that it seems new : http://www.spondoolies-tech.com/products/holiday-special-sp20-mini-farm-batch-2 you can earn up to 2 USD per DAY Smiley Hardware cost = 5500 USD Electricity = aprox 10 cents per hour This one would have roughly 21 TH/s of mining capacity and would consume roughly 18 KW every hour they run, or 432 KwH per day ( source). Assuming you pay $0.09 per KwH (which is low and below the national average) then you would be spending roughly $38.88 per day on electricity. Based on current difficulty you would earn roughly 0.2002 BTC per day assuming you have 100% luck. Based on a $250 price of bitcoin that works out to $50.05 per day of revenue. If you were to assume the price of bitcoin is $200 (where is was only a few days ago) then you would earn only $40.04 per day which although is above the cost of electricity, it does not give very much room for error. http://www.bitfury.org/productsBF4500 Cost : around 10,000 USD Specifications 4.5TH/s 3000W you can earn up to 15 USD per day without electricity cost. Please correct me if I am wrong. I don't see where you got your cost from. However I would agree with the rated hashrate and electric consumption. The gross revenue would be closer to $10.72 assuming a price of $250 and closer to $8.58 assuming a price of bitcoin at $200. In order to realize $15 of gross revenue you would need to assume the price of bitcoin is ~$350. Based on 3 Kw per hour of use of this device, you would use 72 KwH per day which works out to $6.48 based on $0.09 per KwH. I am not sure what your point is. The SP20 is an older model miner |

OMG! BurtW was a great guy and very active here. I believe he mostly did cash transactions, I hope this isn't another one of those localbitcoins "stings".
I'm afraid it might very well be. he needs a good lawyer. Has there been many of these "stings", whereby the undercover officer mentions illegal activity halfway through the deal and thus "entraps" (IMO) the suspect into incriminating themselves if they continue the transaction? from the Tips for local transactions thread: https://bitcointalk.org/index.php?topic=137272.0the general rules include: - agree on price and procedures in advance
- meet in a neutral place with video surveillance and secure wifi
- verify that both parties have all the required Bitcoins and cash
- perform incremental transactions, exchange small amounts first
- if the other party wants to change the procedure, walk away
- never do a transaction with anyone who tells you that it will be used for something illegal
Those rules don't work because you're still acting as a money services business and most LEOs will make small trades first to build trust. Hell, they might even take you out to dinner and go bar hopping with you first. I don't think law enforcement is out to get people who are selling bitcoin like this. I would speculate they are primarily after people who are willing to trade with people that openly admit to intend on breaking the law with the bitcoin they are purchasing/selling |

If the manufacturer is providing the hardware at cost then it would be contrary to your above point because they would not be making any money off of the sale.
The cloud mining contract is the sale, not the provision of miners. The third party would need to make it's profit from somewhere. There needs to be a difference between the amount that is sent to the manufacturers and the amount they receive from customers. There will also be additional costs like paying someone to monitor and adjust the miners, someone to handle customer service, someone to handle potential customer's questions, someone to handle payouts. Plus management to manage these people. |

If you still have your old wallet backup, you could extract your private keys and import them into another client. You can then access your old addresses and send the coins to your new wallet. There is no need to ask for refund from blockchain.info.
The private key associated with the address the withdrawal was sent to were compromised and an attacker was able to sweep the funds into an address that they control. As a result the OP has no way of getting the funds to himself. |

Nefario taught an english class in china. he had some assignment where he got his students to do something on the forum. That's all I can remember. edit: Sorry, mixture of slow and lazy.
3 Classes we're involved, with roughly 80 students per class.
The classes were broken into companies of their own choosing, each company needed a CEO and CFO
And that's all the rules really. The general idea being that they had to do business with foreingers for bitcoin (as at the time only Westerners had bitcoin).
When I started I did have lots of complicated rules, but that just confused everyone, so kept it really basic MUST MAKE BTC, marks given for genuine effort.
The total amount earned by all companies combined was 75btc in a period of about 1 & 1/2 months.
The largest being 31 btc by a single group.
Next being 16btc
10,8....0
There were 17 companies, only 8 of them had any bitcoin at all, the rest got nothing.
I had expected an internal market to develope where companies would specialise and people would be lent from one group to another for a price but nothing like this happened at all.
What did they do?
Apart from spamming the forum and pestering people here are some of the things that we're tried.
Translating Chinese jokes to English
Selling Mp3's and video's about Chinese culture
Making a Chinese cookbook and attempting to sell recipies.
Having a magazine about Chinese medicine
Making two homemade KungFu Movies (which were actually very good but no one bought)
Giving advice on how to enter the Chinese market, open a Chinese bank account etc.
Selling traditional Chinese Medicine advice.
Begging.
The most successful of these was translating jokes, so successful that it convered the majority of bitcoin for the first 3 groups (two of which saw how we it was working and jumped in).
Problems
Language, obviously many of the students could not write a clear advertisement to save their lives.
Understanding bitcoin
Knowing how to use a computer
Having a computer or internet access (most students dont have).
Product ideas.
In roughly the above order.
Of all the students involved about 20 really made an effort or took part. And it seems to be those from this group that are continueing to use bitcoin (after counting they asked for their bitcoin back).
In most ways I would deem this experiment something of a failure, it was poorly executed on my part, and most of my hopes (of developing an internal market inside the college based on bitcoin) came to nothing, but there were some minor success.
Most of the winning companies were in the same class, most of the failing ones were together also, it seems success and failure are contaigous.
Questions?
Wait, aren't bitcoins illegal in China? Or did he run this class before China banned them? China banned bitcoin in 2013 (using the word banned very loosely). The experiment was done in 2011. I find it interesting to see just how many problems the experiment had. I would never had though that so many college students in China would not even have access to a computer. Maybe his experiment had some level of impact on the chinese eventually adopting it the way they have so far....... |

Do you ever think that cloud mining will become profitable again?
It still is, just over a longer period of time. This is not true. As it stands now it is not profitable having your GHs running at CEX. They will become even less profitable as time goes on as the difficulty tends to increase (although the adjustment in ~3 days will likely be an exception to this). You need to remember that when you are cloud mining verses "home" mining you are adding an additional layer of people who need to profit which will make it generally less profitable then if you purchased your hardware yourself He never said CEX.IO. He said cloud mining. All the manufacturers offer their their own services now so it means being able to mine without having to pay for shipping, PSUs and ridiculously expensive electricity. That is just one example. A PSU is just a capital expense and can be sold when you no longer need it for nearly the entire cost. You still must (indirectly) pay for shipping as the manufacturer still needs to ship the miners from where they produce them to wherever they will be hosted. Electric costs vary from place to place so your argument that you pay higher electric costs by running them at your home is invalid. This topic is about cex therefore it should be assumed that he was talking about it. Even if he was not then the overall point of my post is still valid. Mining rewards (net of maintenance) will generally decrease over time as the difficulty increases (although this time around the difficulty will decrease, although not enough to counter the fact that the price of bitcoin has fallen so the net mining reward will still be lower) |
