Okay I am planning on getting a R-BOX Rockminer 32-37GH/S as my first bitminer and I have seen good things from it but I am still on the fence about it. Can I just it some more input from others on here about it.

Good gear but uses a lot of power.

You are talking about the small sized one the bigger one does about 100 gh.

It needs a pc or a rasp pi to plug into.

So more power used.

Why do you want it?

It it your first piece of gear?

is waste of money because you will get only 0.0007106 bitcoin per week with this

home mining is not worth any more expect you want only to see how it works and only for hobby.

Are you looking to learn with it?

It will spend  close to 50 watts with a rasp pi running it.

Maybe more like 60 watts.

Yes this well be my first piece of gear and I am just planning on trying to supplement my income not get rich.

I'd recommend you to look into for example Bitmain's Antminers (Antminer S7 is the newest) or Canaan Creative's Avalon -miners (Avalon 6 is the newest).

If you do not have free power this will lose money.

It is basically 1 watt gear.

The s-7 is .28 watt gear

The avalon6 is .31 watt gear.

If you pay 10 cents a kilowatt you need .4 watt gear or better.

To have any chance of profit.  If you want to learn and point it at ck's solo pool

It would most likely never hit but you could learn.

What do you pay for power?

I'm not really sure this is what was stated on the top on one my last bills 1P 3W 240V-KWH not sure if that is helpful

Those are a little out of my price range unless the pay for themselves off fast.

I think very few people try and "supplement their income" via Bitcoin mining these days. To see where you are in terms of income (not profit) and your mining hardware, take a look at:

https://bitcoinwisdom.com/bitcoin/difficulty

On the left hand side of the page, you'll see a set of boxes with 1  filled in for GH/s. You can over-type that box with 32, and all the other numbers will adjust. You'll see that your income will be about $.30 (30 cents) per week. If you spend 30 cents per week generating that, then you aren't really earning anything. That why the current bitcoin profitability discussion revolved around:

- Electricity cost where you are mining?

- The current price of BTC (i.e. how many dollars for BTC).

- The efficiency of your mining hardware (i.e. how many GH per watt of electricity used)

- The cost of the mining hardware.

- The upcoming "halving" (i.e. in roughly July the BTC reward per block will be reduced by half).

Don't be surprised if the picture pained by the number is pretty bleak in terms of earning money. Bitcoin is, and has been, become a more and more centralized production enterprise these days. While it's interesting to learn about and such, it's not likely to provide many folks much in the way of "profit".

If you have free electricity, you might manage to eventually achieve RoI on that Rockminer.
Otherwise, forget it except perhaps as a hobby/toy type thing - it's TOO inefficient to make a profit at most available electric rates.


 NOTHING currently available is going to "pay itself off fast" - even with VERY VERY cheap electric (3c/KWH) nothing currently available has a reasonable chance to pay itself off before the halfing kills it's profitability.

 The golden age of mining ended years ago.
 The silver age of profiting easily due to the SP20/S5 price war has been over for months.
 Now us small miners are hoping the 14/16nm gear initiates a bronze age.....

I would say it's a good option to kick in your mining experience but don't think of getting ROI (at all). Another option that would be within this range is Antminer U3 (although it's not as efficient as other expensive miners) but it has 63GH/s although it's a bit unstable. The good thing is many of users have bought U3 and as result you could find a good 2nd hand U3 on this forum with good price as opposed to R-BOX (since I've seen only few bought it as comparison to U3 - over the years).
