Topic: [www.easy2mine.com] 340$, the group buy of antminer s5(psu included) - page 69. (Read 123463 times)

Got my 3 miners.  Two of them had to be opened up to fix loose cables.  One to the ethernet, and the other to the blade.  After that the miners started working and are hashing away just under 1th for the last 2 hours.  These ones had different subnet mask and gateway IPs that i had to set that were different than my first batch of dragons.  Just in case anyone has issues, check those fields.

pcfli just PM'ed you

that is what the most of the people thinking currently, but i donot think so that the 17% increase on difficulty for 11 days will really happen by now, it is no reason, on one hand, you assume an very high increase ratio and on the other hand, you point out that wisdom people will not invest in miners. these two things are against each other naturally.
here is my roi analysis and i paste it here again
          ROI analysis
Many people make decision whether the miner is worthy to buy on ROI analysis , and i will share my thought on it with you.
First, you need to consider the following two questions:
is the mining itself will disappear after six month?
What is the speed of the fastest miner can perform after six month and what is its price? 

I will give you my answer to these question.
is the mining itself will disappear after six month?
The answer is definitely no, only the bitcoin exist, no reason that mining itself will disappear, and like most of the people in the forum, i have strong faith on bitcoin.

What is the speed of the fastest miner can perform after six month and what is its price?
I can’t tell you the exactly number of that, but my answer is not exceed 2T with the electricity consumption of 1000 watt, during the last one year, with the appearance of ASIC, the hash rate speed you can gain with 1000 watt has increased from 6G to 1000G. But it is almost the best value we can achieve based on current technology. Although i am not an professional electrical engineer, i can see that the increase of the hash rate of the chips are closely connected with its manufacturing technology, which have been increased from 110nm to 28nm by now. But as i know, it is almost achieve the limit of current chip manufacturing technology also the limit of physical law. Although 20 nm manufacturing technology is possible but the cost will also increase rapid and may be not worth to use. So we can achieve the conclusion that the life time will more than 6 month.

Now we can go forward to the second question here, what is its price.
I cann’t answer this question exactly also, but i does know that its price will not below its manufacturing cost. That is very simple to understand, the factory have no reason to sell them unless they can profit. As i know, the manufacturing cost for one dragon 1T miner will not below 1000$(chip, psu, Raspberry Pi, fans, shipment fee, all these thing need cost and will not disappear) .


Now we can go back to the ROI analysis, for most of the roi analysis, it will assume one miner will only have 2-3 month life, but based on above analysis, we can see that will not happen, so there is must something wrong with the current ROI analysis.

Here is my third question, what is the the most possible number(in %) of the adjustment of difficulty for one round (12 days) in Oct 2014?
I will give my answer later, but now, i want to hear your guys opinion

Last post since I don't want to derail pcfli's thread, but when you start a reply with "FYI,you will lose money and this miner is no longer profitable" in someone's thread who is selling miners instead of the appropriate Speculation section you should expect some upset miners.  There is always going to be the debate of mining BTC vs. investing BTC, but again this is not the appropriate place for that discussion.  

Who will support the BTC network if people didn't mine?  Purchasing miners with BTC strengthens BTC value and is another transaction for miners to confirm.  For a healthy BTC ecosystem you must have investors and miners sometimes they are not mutually exclusive.  


Anyway, thanks to those who have purchased Dragon Miner rebate coupons.  I have 11 more $50 rebate coupons $35 each or $50 buy on get one free.


Lee is rolling in the dough now.  He has hired a few hotties to "work" around the office.  

Yep, can see the tracking for mine.. Its on the way
Thanks also for testing them, knowing my luck I would have got a bad blade one  !

But the resell value is going to be higher and the power usage less than what I have now.
I have 6 x s1 ants running sucking 2280watts of power right now + the power supply bought for each one getting a total of .12 to .15 btc a day right now.
One dragon miner does the same for 1000 watts of power on one small footprint..
I might buy more yet and get rid of the ants

Jeez why is everyone so defensive? Just giving a heads up. All I'm saying is that if you were to invest money now, it would probably be much better spent buying BTC. You will end up with more BTC in the long run.

If you buy the miner, it would currently cost $2900 or around 6.4BTC. You will mine at most 5.5BTC and if you sell the miner, maybe you can get 1 more BTC. Maybe. It's a losing deal no matter how you look at it.

I have hired two girls to send advertisement with the account leegroupsale.1 and leegroupsale.2, but your guys still need to confirm the deal with my account: pcfli or email: [email protected]
sorry for the confuse,

all units in the batch of Apr 5 were sent today, all track NO. was also updated with buyers, most of the compensate were sent together, sorry for the delay again, hope you will receive them soon, the good thing is i have tested all the miners for three days and repaired the minor problem, two miners with defective blade was sent back to factory, so you guys will receive a good miners this time

Got my compensation for late and tracking number.  Thanks Pcfli!

Thanks daddy.  I appreciate the feedback.  I would pull the trigger if it were not for the poor profitability.  Can't see spending losing a bitcoin for the trouble.  But will keep watching.

Hi pcfli,

How things are going, you will ship today and send compensation to all buyers?

Regards,
Lenny

Thanks for the info OG

Assuming a static BTC value you maybe correct, but it was only a month ago that 1 BTC = ~$650 so it is extremely difficult to speculate on BTC value and mining.

I will gladly invest in your crystal ball that gives you the ultimate knowledge.

This is always an option, and though I am new this particular thread is about buying a particular miner not weather or not its still profitable.  There are other forums for speculation on profitability.

Thanks for the insight all the same

You can always buy btc while the price is low.

trader59, if you do not wish to buy a miner then do not buy one.  Why troll about and spew your nonsense?  What do you have to gain by tearing down others?  No trolls needed on this thread.  Thank you.

FYI, this is no longer profitable. It currently costs 6.4 BTC and at most you'll get back 5.5BTC with 17% difficulty increases. At most, you can hope to break even by selling the miner.

I agree, Lee is a great business man.

I wish the manufacture can hire him to handle sales. They will make tons more sales directly, completely bypass all the reseller.

Not a problem. I know these things happen, and I do appreciate you working with me to fix the issue.
