I stopped using localbtc since I am going from mining with a single card to mining with 10 rigs, so that all these selling and receiving money from unknown Individuals in my account activity might trigger some unnecessary doubts in my bank peoples mind (or It may be just me being paranoid). In Unocoin's case it is a registered and legit company, so there isnt much to worry about.
May be that might create some issues,because if the money you are receiving is tainted then you might get into trouble,you can never know what kind of people you are dealing with,the chances of that are really low,but it is better to avoid that risk because a user named Pankaj Bhardwaj claims that he got into trouble because of that and the police linked him with some illegal activities because of the funds he was receiving and he never had any idea,so i would advice to deal with legal exchanges.
Well why not try here on forum where you can buy/sell btc as probably you will get much better rates than what you sell on Unocoin. SO how profitable is mining and from when you are mining and what is your total expenses per month?
I am starting this July 1st week, as I am waiting for the new mining cards to come from NVIDIA. With my single card, mining for nicehash I am making an avg. 30-32 $ per week. This may be because I am dual-mining Eth + Pascal and also running cryptonight on my CPU (4770k). So, now I am planning (if the new cards come around 15 to 20k INR), to build around 6-10 rigs with anywhere between 40 to 60 gpus (depending on price) because my budget for the build is around 12.5 Lakhs.
I ve made a list of my build based on AMD A-series processor, FM2 motherboard which supports upto 5 gpu, DDR3 RAM, Riser etc..etc..and everything does fit inside the 12.5 L Budget. As for the profitability, I am not expecting any miracles since ethereum difficulty is already rising exponentially, but still I am optimistic and hoping to hit ROI within a year or year and half. As for monthly expenses, I get electricity for about 4.5 rs/ kwh when I register as an SSI unit (IT Industry). So, that is very convenient.
Since, this is going to be my full time business and I am kind of paranoid about what user (Marma Kalari) said, I would only be dealing with Unocoin or coinsecure and the like to avoid any 'Snag' on my way, since that ll be the last thing I would want to happen.
