What does it take to mine 1 Bitcoin?
Posted on Jul 19, 2013 by Paul White
When you are considering upgrading your computer's hardware in an attempt to mine for Bitcoin
, one the firs tthings you want to know is how much processing power does it take to mine a single Bitcoin
, and how long will it take? I have worked the numbers based on the current difficultly level.
|Amount to Mine||How Fast||Hashing Power||Via GPU||Via USB ASIC||Annual BTC|
|1 BTC||370 Days||138 Mhps|
( My current Pathetic Setup)
|GTX 560 Ti||-||< 1 BTC|
|1 BTC||90 Days||572.83 Mhps|
(Where I will be in a week)
|HD 7950||2x||4 BTC|
|1 BTC||30 Days||1.718 Ghps||3 x HD 7950||5x||12 BTC|
|1 BTC||14 Days||3.682 Ghps||3 x HD 7990||11x|| 26 BTC|
|1 BTC||1 Day||51.555 Ghps||43 x HD 7990||154x||365 BTC|
|1 BTC||12 Hours||103.11 Ghps||86 x HD 7990||310x||730 BTC|
|1 BTC||1 Hour||1.237 Thps||1031 x HD 7990||3715x||8760 BTC|
The previous values were based on the Difficulty Level Today.
You can see my current setup. The GTX 560 Ti makes a pretty lousy Miner. Just purchased a used 7950 off ebay, which should help me generate a few coins. I will only be running my system during the day when I work, so After a year I might have earned 2 BTC. I might add some a second 7950 or upgrade to the 7970 depending on where prices go. The 7990 would be nice but its just priced a little too high for my tastes. $500 for a used Video Card is a bit much.
However next year or this fall, when I build a new workstation I am going water cooled all the way, so I should be able to push my system pretty hard assuming bitcoin
mining is still profitable at the future difficulty level.
So if you were thinking of getting rich mining for bitcoin
, now you know how much power its going to take.
