Hey,
I am a regular bitcoin user. No, I do not own a ridiculous 10 Ph/s bitcoin mining farm in Antarctica with liquid nitrogen cooling. I have a normal computer with your standard r9 280x (7970) GPU. I can hash at around 700Mh/s and for scrypt I can hash at 720kh/s. I am here to tell you very bad news. If you are in this for profits, leave now, right now. I can generate 27 cents a day with BTC with my over average GPU that most regular people will not have. Or, I can mine scrypt coins and depending on the coin make at least 8$ a day, which could get you some good quality free beer every day
. Even standard ASICs are getting to be unprofitable. The BFL Jalapeno is 230$, and mines at 5 gh/s. That is probably the most popular ASIC for its attractive price, and noob friendliness. With one of those, I would make approximately 2$ a day. A BTC ASIC, made for mining BTC and nothing else, makes only 2$ a day, and then theres power costs (although fractional). Once mining is irrelevant, that machine is useless. All it does is generate heat, waste electricity, and looks good in the corner of your room. Buying a graphic card for 1.5x the price, will mine 5x more money in a day (yes take up more power, but this is only 1$ a day of power), and once scrypt mining is obsolete, you will have a very very nice GPU to play games with, edit video, or do other things. At least you could do something with your miner!
All I really wanted to say in this post, is that I don't reccomend mining BTC at all, even if you are going to buy an ASIC. And even if you already have a nice GPU like mine, and even want 26 cents a day, just don't. It makes noise, destroys your graphic card quickly, and generates tons of heat. Even if I had the capital to invest in a very nice ASIC, I probably wouldn't because, what if BTC crashed the next day, and all I had was some stupid brushed metal box. At least if I spent twice that much for the same hash rate in GPU's, I would have a ridiculous amount of gaming power, and could sell those cards, or build a supercomputer or use them as a heater for your house. I don't know what you want to do with 100 GPU's. The possibilities are endless!
Thanks for reading this, and please take my advice to stop mining those stupid
BTCs. We need to start using it as a currency!
