Questions about mining bitcoin

[SKYBTC]

Hello all I have some questions on the subject  mining bitcoin

I have to search for devices bitcoin mine, and I found a lot of different devices and I do not know, whichever is better for me

At the outset I would like to do mine to do support my site with bitcoin And sell surplus of bitcoin


now i find all most 4 device

1_ spondoolies divices  with 5.5 TH/S

this is description from official site 

The SP31 included an improvement to the ASICs that delivered more hashing for the same power consumption. With the SP35 we replaced the PSUs to squeeze out even more out of the RockerBox ASICs. This new design will deliver 5.5TH/s while maintaining a slim 2 U case suitable for both home and data center hosting. Note: With the current power draw the SP35 is only suited for 208V and above power outlets.

I have bought from bitmain and have been VERY pleased.  Fast delivery, hasing matching the quoted hash rate.


coinwarz.com will answer all your questions about profit.

REMEBER as the difficult goes up you get less reward from mining, however it seems to have steady out.. thank god for me my S3's are still profitable .  Odds are high I will buy the S7, and S6 that only runs on 240vac would be useless to me sad panda.

I would consider only buying one or two S5's and waiting on the S7, maybe even grab a used S3 super cheap.

Here questions

1. any use of the best equipment and longer lifetime and efficiency
- all 3 of those compines have solid reps, I have bought bitmain products, all of them have been running solid, my S1's running solid for a year and a half straight. 

2-I watch a difference in the price Is price of the device depends on the hash rate or other factors.
I don't get your questoin.. coinwarz.com

3-how many bitcoin can i mine by this deceive cointerra or Bitmain or spondoolies  and how calculate amount of bitcoin can i get from any device
coinwarz.com will answer this.

4-bitcoin amount be specific amount per day does increase or decrease difficulty
coinwarz.com hehe

5- this machine work 24 hour or what  and must be use additional Cooling fan as example
no extra fans are required for these units, I HIGHLY stress they should be in a low dust area.  Or put panty hose over them and clean the panty hose every day.

6-Are there certain characteristics of the laptop or desktop device user with bitcoin mine devices
these all have controls built int you don't need your laptop or desktop to control them only to set them up.

I think he meant to ask how the price of the devices (the miners) varies - that is, if, and to what extent, it depends on speed / hash rate, power consumption, efficiency, and so on.

[jt byte]

I would answer the 5th one.
5- Yes they are made to run for 24h and to keep them more secure for you, you can add external fans.
To keep them cooler than they are. This is additional so you can put them or not.

You're fabricating "facts" about the S6. It hasn't been released so how do you know that it only runs on 240v?

yeah bitman

that miners that you linked isn't good at all too heavy in cost, with the same price you can buy 5 S5(used), which have better hashrate(1155 x 5 vs 5.5) and lower consumption(590 x 5 vs 3600)

[alh]

Assuming you are interested in earning more money than you spend, your FIRST and most important question to answer is:

What is the cost of electricity where you will run the miner?

If the answer is less than 10 cents (i.e. .10 USD) per KWh, then it makes sense to worry about all the details above. If your cost is over about 15 cents, then you will spend more on electricity than you earn in BTC. Only you can answer the questions regarding your electricity price, and how important it is to make, or not lose, money by running a Bitcoin miner.

1. I have friend who use Cointerra device, he has been using for one and a half years and still good till now 
2. I do not understand about this question
3. For Cointerra if using difficulty today you can make BTC0.01/day
4. Using this calculator for calculate increase or decrease difficulty https://alloscomp.com/bitcoin/calculator
5. Yeah this machine work 24 hours I think dont must be use additional Cooling
6. This does not run itself does not need a laptop or desktop

Hmm, are you sure the video is recent - that is, that the difficulty at the time of shooting wasn't significantly lower (maybe early last year lower)? Or perhaps the video was referring to those 0.22 BTC daily as coming from more than one miner, or within a pool?

Using the www.coinwarz.com calculator for the Terraminer model you posted above, current difficulty, and assuming I'm not missing something, I don't see a single miner as getting more than about 0.015 BTC daily - not considering the costs to run the miner.
