Does anyone here do it or know the cost comparison between coins and cost of electricity. Or have knowledge of mining rigs?
Don't. It is no longer profitable to mine BTC. Not unless you have massive capital. Your best bet is LTC mining. Much more profitable for miners. The profit margins are extremely dependent upon your hardware and utility cost. ---------- Post added 29th Jun 2014 at 05:27 AM ---------- Litecoin Mining Calculator and Profit Calculator - CoinWarz - Scrypt Hash Rate 11,000.00 KH/s https://litecoin.info/Mining_hardware_comparison Also, https://www.havelockinvestments.com/fund.php?symbol=AM1 However, I must point out that depending on your opinion of BTC, many believers of bitcoin believe it is far more profitable to just buy bitcoin outright. I tend to agree. Also note that the difficulty of mineing BTC rises dramatically month over month. Thus hardware that you purchase might seem to have a breakeven point of a year or less, but once difficulty adjustment is accounted for you might never break even. Also, I love btc and it has been my passion for almost two years now!
I'm not in any way discouraging you, but it is no longer feasible for ordinary folks like us to mine bitcoins. Bitcoin's cryptography today already escalated into big number crunching, that requires computers that costs tens of thousands of $$. Only big time companies and organizations with deep packets can afford high-end computers to do the complex number crunching nowadays. It is a very different now than lets say 2-years ago when an ordinary Pentium-based computer can resolve a bitcoin crypto-mining numbers.
