SP20 Jackson Bitcoin Miner Review

Would bitcoin mining me worth it for me?

Okay so i have about a 1000$ i can use to get started with a setup.. I will be going to school full time in about a month so for the next 7-8 months i will not have to pay electricity.... With this amount of cash and not having to pay for electricity what type of yeild should i expect to make per month in bitcoins and $? Im a noob at bitcoins so be gentle lol

I'd like to invest in some ASIC machines, any advice on which to chose?

I am thinking of buying one or two to start, to see if it's feasible to make some profit and then looking to invest in up to 20 if it works out. What are some of the better machines on the market, I'm basically looking for some Watt per GH figures and also which machines are reliable and which to stay away from.
I should add that I am looking for some module / card type devices like this so I can scale up at comfortable rate.
Thanks muchly.

Getting started mining, Any tips?

I am brand new to bitcoin, I am hoping to mine some bitcoins. I am thinking about using https://github.com/ckolivas/cgminer and using Slushpool as my mining pool. As for hardware, I have the sp20 jackson. I am wondering if anyone has some tips for me about mining.
Thanks!
EDIT: I am not doing this (fully) for the money. I am mainly doing this because I want to learn about bitcoin mining, However I would like to at least pay back the machine.

My roommate and I have free power in our college dorm should we invest in some miners?

So I'm really on the fence whether to drop 200 bucks for a used spondoolies sp20 and some power supplies and was wondering if some pros think it would be worth our time to start with this and get a few more later since we have free power while in school? Also would a used sp20 be a good choice or would there be something better, it seems for the price/GH's this one would be the best but im a little worried about a used product.

New miner. Want to make a little set up. Need help.

Hi there!
As the title suggests im willing to jump into bitcoin ,but i cant figure out what would be best.
Before we start ,yes i have electricity included into rent ,so i dont have to worry about that.
I want to invest around 300£ and was wondering what would be the best i could get for that amount? I have been looking at Antminers ,but i just found Spondoolies SP20 and it looks like a reasonable deal.
What would you do if you had 300£ to spend on a set up?
Thanks for the replies in advance!
Keep mining!

-Limits risk and cost of equipment failure, and associated down time due to failures
-Saves shipping costs for heavy PSU's to and from hosting location for duration of your contract
-No equipment depreciation
-Helps eliminate ownership problems associated with Group Buys, when more than 1 member shares purchase price of PSU to host together
-All maintenance, replacement, shipping, setup, and lost revenue from down-time due to PSU failure is my responsibility
Please contact me for details.
Shipping
Shipping will be calculated individually, to make sure you are getting the best rate. All prices are in USD. I am willing to accept escrow through OGNasty, and can also do Paypal but buyer will be responsible for covering costs of either services (4% added to paypal, OG charges 1% for escrow).
Each package of PSU, breakout board & 10x PCI cables is approximately 16 lbs.
The BTC address for all non-escrow breakout board orders is here: 1GWQYCv22cAikgTgT1zFuAmsJ9fFqq9TXf I will not PM you asking for payments to any other address, so beware of F1nksy, Fink5y, or whatever scammy names might pop up.
Original Post:
Hi everyone,
I am the official North American distributor of Break-out boards for the IBM 2880W Bladecenter H PSU's, which are 80+ platinum rated (94%+ efficient) Edit: UN-VERIFIED AT THIS POINT and have provision for 22x PCI-E cables. Unlike other server boards, these don't rely on screw-down terminals and bare wires which can get loose and spark causing fire hazards, and limit the exposure of live contacts to surfaces above and below the PSU. Instead these use a double-sided PCI 6 pin cable, which only cost about $0.10 more than the standard PCI-6 to bare wire versions. Also, unlike the DPS-2000BB -which is the next largest server PSU available for miners- these have fans already built-in, so don't need extra work to set up up and deploy.
The PSU's themselves are available on e-bay and elsewhere (I sell them as well), and the boards will be priced at US $70 $65 each (better pricing for bulk purchase, volume structure will be the same as J4bberwock's). Each PSU can handle 2x Antminer S7's, 3x SP20's, 5 Antminer S5's, or 8 Antminer S3's. You won't find better value for power, and there are very few ATX-based PSU's that provide 80+ platinum efficiency (and none for under $200 for even 700-800 watts). Edit: UN-VERIFIED AT THIS POINT Lastly, unlike ATX-based PSU's, these can be run at (and I have found even over) their rated power, as they were designed that way for server use. They do, however, require 240V input. Also, running these over at over 90% load will give you slightly decreased efficiency, and could affect their reliability.
I have personally taken 3x SP20's to settings around 960 watts (at ports, not at wall) each for approximately 2 weeks, and the PSU drew 13.41 amps (@ 235 volts - 3150 watts @ wall). So at absolute full load (or possibly over), these will still hold over 90% efficiency. Very impressive, and I will be testing different fans to reduce sound for home mining (fans on these PSU's are slightly louder & higher pitched than SP20 fans). Sloopy informed me that he ran 11x Antminer S3's on a PSU for a while (over 3,300W DC!), but that is certainly not recommended, and will eventually cause the PSU to fail. It is simply a testament to how tough these PSU's truly are, and that spikes over their rated output shouldn't affect performance.
Here are some pictures:
Feel free to contact the developer of these boards if you have any concerns, he will verify that I am authorized to sell these. https://bitcointalk.org/index.php?action=profile;u=206446

Hướng dẫn cách kiếm tiền bitcoin bằng điện thoại cho nhà đầu tư Việt

Hướng dẫn cách kiếm tiền bitcoin bằng điện thoại cho nhà đầu tư Việt. Đào hay khai thác Bitcoin là quá trình mà Bitcoin và các loại tiền điện tử khác được tạo ra hay mua bán ethereum giá rẻ trên sàn giao dịch một cách nhanh chóng nhất.
Đào được thực hiện bởi các mạng phân quyền của các cá nhân, hoạt động độc lập hoặc trong các nhóm lớn. Một thợ đào cá nhân được biết đến như là một “nút” (node). Có hai mục đích của việc đào: một là để tạo ra nhiều đồng bạc hơn, hai là để xác nhận tính hợp lệ của các giao dịch sử dụng tiền trong lưu thông, một vấn đề quan trọng không kém.
Hãy lấy Bitcoin làm giả dụ. Các giao dịch được thực hiện với Bitcoin được nhóm thành các “khối” (block), được xác nhận bởi các thợ đào (miner). Có động lực tài chính cho các thợ đào xác minh những giao dịch này.
Đào Bitcoin là quá trình giải các thuật toán phức tạp với máy tính nhằm xác minh một khối (block), khi đó thợ đào sẽ nhận được một số lượng Bitcoin mới được coi như là khoản thưởng, và một khoản phí tổn giao dịch.
Máy đào Bitcoin là gì và cách kiếm tiền bitcoin bằng điện thoại
Máy đào Bitcoin hay còn gọi là trâu cày Bitcoin là thiết bị giúp những người thợ khai thác bằng cách giải các thuật toán và kiếm được Bitcoin.
Có hai loại máy đào tiền điện tử, một là loại máy chuyên dụng được thiết kế ra chỉ để đào bitcoin, không đào được các loại tiền điện tử khác cũng như không làm được công việc gì khác. Một số loại máy có thể kể tới như AntMiner S7, Avalon 6, SP20 Jacson,
Đặc tính của các máy này là tốc độ đào nhanh và cập nhật thông tin tiền điện tử, ổn định, giá ở nước ngoài từ 250$ – 500$. Bên cạnh đó nhược điểm là nó chỉ đào được bitcoin, không sử dụng vào mục đích khác và khi cần thanh lý thì rất khó. Bởi thế ở Việt Nam ít “thợ mỏ” nào sắm máy này.
Một loại máy đào khác rất được ưa chuộng tại Việt Nam và được đầu tư ào ạt đó là máy PC được gắn một hoặc nhiều VGA có cấu hình mạnh. Sau đó cài phần mềm mining vào máy này và chạy nó 24/7 để nó đào ra bitcoin và các loại tiền điện tử khác. Nhược điểm của nó là giá cao, tiêu thụ điện nhiều, chạy nóng, tốc độ cũng không bằng máy chuyên dụng. Nhưng ưu điểm là đào được nhiều loại tiền ảo khác (thường thì ít ai đào bitcoin vì nó có độ khó quá cao mà người ta tụ hội đào những đồng bạc có giá trị thấp nhưng dễ đào hơn rất nhiều như là ETH, ETC, XMR…), dễ dàng thanh lý,…
Ai cũng có thể đào? Về mặt kỹ thuật, đúng vậy, nhưng với Bitcoin, sự phức tạp của các thuật toán đã tăng lên rất nhiều, do vậy, số tiền mà bạn sẽ phải bỏ ra để tăng sức mạnh tính toán còn tốn kém hơn là số tiền bạn sẽ kiếm được từ đồng xu mới và phí giao dịch từ việc xác minh khối giao dịch. Nói tóm lại, bạn sẽ lỗ.
Chính vì lý do này, các thợ đào hiện giờ tạo thành các nhóm lớn gọi là “pool” để kết hợp sức mạnh tính toán của máy tính (gọi là “hashing power”).
Do thuật toán của Bitcoin, một số lượng lớn các máy tính làm việc cùng nhau có cơ hội tốt hơn để mua bitcoin sàn nước ngoài các thuật toán một cách nhanh chóng và thu tiền về – trong khi chi phí được giảm dần.
Những “pool đào bitcoin” (hay còn gọi là mỏ đào Bitcoin) này thậm chí đã phát triển thành các thực thể tiêu dùng, những người dùng thường xuyên tham gia sẽ mất với một khoản chi phí, phần nhiều các mining pool đều có thu chi phí trên lợi nhuận của mỗi thợ đào.
Tôi vẫn có thể tự đào các loại tiền tệ khác độc lập không? Vâng. Một số loại tiền mới hơn, và những loại có các thuật toán khác với Bitcoin, vẫn còn có thể đào chỉ với một chiếc máy tính. Ngoài ra, lợi nhuận có thể nhỏ và thậm chí đồng bạc có thể bị xóa đi do giá trị biến động.
Hãy nhớ rằng: Loại tiền mới được tạo ra sẽ có thiên hướng biến động hết sức. Ngay cả khi bạn kiếm được lợi nhuận đáng kể trong một ngày, cũng có thể dễ dàng biến mất trong thời gian tới, để lại cho bạn một khoản lỗ bởi tổn phí bạn bỏ ra cho máy tính để thực hiện công việc đó.

Help with selecting Bitcoin Cash mining pool.

Hey so a friend gave me some old miners (SP20's), but I was wondering what pool I should use. I am mining on bitcoin.com but wanted to know if there is another where I'd might have more luck?
I'm cranking out 2.4 Terahashes right now at 800w, and I know I'm gonna lose a bit of money but I really love the real Bitcoin, and want to help the network.

What are you doing with your SP20? Pool, Solo, or Shutting it Down?

With the drastic increase in mining difficulty my SP20 I feel, is on it's last legs.
I have it down clocked about as low as I can get it to run stable which has left with with 1080Ghs @ ~550 watts (it's been REAL cold here this winter). My power cost averages lets say $0.10 $/kWhr. So while I'm still profitable, it's not very much.
So my question is, what is everyone with this generation of equipment doing? Shutting it off? Operating on projected bitcoin values? Solo mining? I'm open to advise as this was my first miner.
Thanks!
