Re: ★★DigiByte|极特币★★[DGB]✔$250k Investment, DigiByte Gaming, #DigiByteTip, DigiSpeed
this is a lot to handle at once. I'll start reading before doing anything. for now I'm going to test every single possibility, then chose the best way. I have a vps to test on and I may try with ASIC, and I'm right now going to test my cpu mining and gpu mining.
I've crunched the numbers, partly because I was curious, and partly because I'm a nice guy who wants to lend a hand. 
At current rewards, in order to mine 5000 DGB with modern SHA-256 ASIC equipment, you'll need ~2.4 kWh. With modern Scrypt ASIC equipment you'll use ~7.5 kWh. And with the GPU algos (all very similar) you'll consume ~9.9 kWh.
As you can see, there is quite a bit of difference between SHA-256 and GPU, but whether that difference is enough to cover your fixed hardware investment or not, that is if you buy an Antminer or not and can reach ROI, for example, is up to you to figure out.
The difference between scrypt ASIC and GPU is much less pronounced, but if you've already got a gaming rig set up, it probably won't take too much convincing to just use what you've got and get with installing and configuring your miner since we're only talking about 30-40 cents a day of difference.
Edit: I've always been in favor of rotating out SHA-256 and substituting it with a more widely distributed friendly algo BTW.
I have some old laptops that are no use to me but they still work, I may try to eliminate the display and why not the hard disk too, to minimize the electricity consume, I have like 4 2 (Pentium 4) and 2 (core 2 duo) I may use there cpu.( I have a electronic degree, that won't be a big of a deal)
without forgetting my nvidia.
I tried to do some calculation but, I had really big struggle with mining !! I downloaded the soft and followed the instruction, but my ind kept telling me that I'm not mining, so I changed to the websites that had worker thins so I started mining with there url etc.. and my worker status kept being inactive.
so I had no luck testing my stats.
Crazy, 5000 is a base figure to compare with. It is not the block reward and nothing was said suggesting such. Please read more carefully.
BTW, it's customary to quote the entire discussion, especially when there are items relating to to various parts of the discussion. We don't normally eliminate what you don't want to hear, and only quote what suits you.
If you have a laptop, you're going nowhere fast with mining. Sorry I misunderstood you when you said you were a gamer. Theoretically, you could mine with a CPU, but you'd be looking at maybe 5 DGB a day or so if you're lucky in practice, or, to put it another way, 1000 times less than my comparative figure to work with . . . so if you want to do a mining yield comparison with electricity use, you'd have to divide those kWh usages by 1000. Are you following that? The CPU's you mention are equally impotent - it's the graphic card that matters.
There's an OP, a website, a myriad of information in this same thread that can be searched, and Google (as I pointed out in a previous post). Get serious, will you? Or do you get your jollies wasting other people's time?
As for everyone who is serious, hopefully the time we've taken to post important informative information won't be completely lost and we'll remember where it is to post for future, more serious community members looking to get up and running in a knowledgeable manner.
