Hi. I'm new to BTC. I read a lot about it, but still don't have clue. My main question is: is it worth to enter mining by GPU at this time? BTC is very expensive now and correction is obvious- dunno how deep. I heard about ASIC devices, but TBH in my opinion it is megafake- no one will sell fe. Butterfly BitForce 5 GH/s SC for $274 according to current course; it's better to keep it in mystery and making money by yourself. And as far as I know there is no trusted person who owns ASIC. I configured rig:
CPU: AMD Sempron 145 MoBo: GA-970A-DS3 GPU: 2x Radeon 7870 XT Tahiti LE Club3D 2GB 975MHz or 2x Sapphire Radeon HD7870 XT Tahiti LE 2GB DDR5 256bit (975/6000) [better cooling] RAM 2 GB 1333 Goodram PSU: thermaltake smart 630w (2x 6pin + 2x 6pin from MOLEX) strong single rail HDD: 40GB SATA Case: CM elite 310 140 or Lian Li PC-T60A ATX Test Bench ~770-790 USD for this
According to my researches this rig will be able to generate above 1Ghash/s, power consumption- 500W
Is there any point to enter at this time with this rig to 'miners company', seeing that correction will come? On current course it is very profitable (investment will pay for itself after 3 months including electricity), but will this digger earn even for electricity after correction? I know that is the relationship between the number of miners, difficult and BTC course, but TBH I don't know how it exactly works and how it can affect BTC course. I will be glad if someone can dispel my doubts even in piece. I know my English sux, but I hope I wrote it understandable
