Great job so far!
I gave u some merit.

Thanks I'm glad you like it.


Shouldn't that read 'ideally less than the value of BTC mined' as in you earn more than the cost to run?

Thanks, great catch I corrected that. Good old night shift fog. Wink

If you are wanting to start mining here is what you need...and what you need to know

This is written for home miners/small farms, but can be used as a guideline for most operations. Use this post as a reference for what you need to research, or what questions you need to ask before jumping in.

What you need to mine can be broken down into the following categories: Hardware, Electricity, Location, Internet connection, Information

This quote by CK is a great launching point to the hardware requirements. It can be found here.

Mining BITCOIN is done exclusively with dedicated BITCOIN mining hardware based on ASICs - https://en.wikipedia.org/wiki/Application-specific_integrated_circuit . You CAN NOT meaningfully mine bitcoin today with CPU, GPU or even FPGAs. Bitcoin difficulty adapts to match the amount of mining done on the network and has reached levels trillions of times too high to mine meaningfully with PCs, laptops, tablets, phones, webpages, javascript, GPUs, and even generalised SHA hardware. You will not find software in this section to help you mine bitcoin in this absurdly inefficient manner in this subforum. It would cost you thousands of dollars in electricity per year to earn only a few cents in bitcoin. Even if you combined all the computers in the world, including all known supercomputer, you would not even approach 0.1% of the bitcoin hashrate today. Any discussion outside of ASIC related mining, except in the interests of academia, will be moved to the altcoin mining section. There isn't any point attempting to mine bitcoin with CPU or GPU even in the interests of learning as it shares almost nothing with how bitcoin is mined with ASICs and will not teach you anything

Hardware

Asic Miner: Here is a list of the companies currently manufacturing Miners for public purchase. Each one has their Pro's and Con's it is up to you to do your research and decide what is best for you. A few points to consider while researching are: efficiency, reliability, warranty period/policy, power draw. Each company has a different way of handling warranty repairs, depending on your situation and the policy repairs can become cost prohibitive. I will touch more on efficiency and power draw in the electricity section.

Current list of competitive hardware

Power supply: You will need to purchase a power supply to run your miners. You will find ATX and Server grade PSU's, the latter being preferred for mining BTC.
When it comes to selecting a PSU purchase something with a capacity 25% higher than your miner is rated to draw. This will have you operating within the 80% rule.(explained further in the electricity section)
EX. Miner draws 1000 PSU should be able to provide 1250W.

** Many current generation miners are now being manufactured with Integrated PSU. Again do your research to see if your unit comes with or without. Generally you will still need to source a power cable.**

Auxilliaries- Avalon miners require an external controller, 1 per 20 miners. You may have to run additional fans for intake and exhaust depending on your location.

PSU's can be purchased large enough to run 2 Miners; or the opposite 1 Miner fed by 2 PSU's. Ensure the PSU you have selected will have the correct amount of PCI-E connectors required to operate your miner(s)

You can also find a large supply of used miners and PSU's. Again it's up to you to do your research as these often are a no return transaction.

Electricity- Follow all local codes and regulations

This is the number 1 factor in whether mining is right for you. As discussed with Miners being a 24/7 machine drawing power those costs will make it cost prohibitive for some people to mine. You need to be aware of what your costs/KWH are and run the numbers. This will be done in a profitability calculator. This is just an example of 1 there are many out there.

(Miner usage in KW)*(Hours run per day)24*(Cost/KWH)=Cost per day to operate (ideally less than the FIAT value of BTC mined)

The second part to the electrical requirements of mining is the available service; written for North America. You will need to figure out the amperage you can spare, what circuits and receptacles you have in place, are you setting up on 220V or 110V. You will need to make sure that you have the right cord end for your PSU to match the receptacle, picking the wrong one can cost you a few days of mining if it has to be shipped.

If you can try and set up on a 220V circuit for 2 reasons. You will pull half the amps, and it is more efficient. Doing so requires 2 breaker spaces in your panel. Breaker sizing will depend on how many miners you plan to run. Here is the formula for calculating amps.

Watts/Voltage=Amps

Here is where you will bring the 80% rule back into play by sizing the continuous miner load to 80% of the breaker rating. 12 Amps on a 15 Amp breaker, 16 Amps max on a 20 Amp breaker, 24 Amps on a 30 amp breaker.

If/when you increase the amount of miners you are running you may want to look into PDU's, as opposed to more receptacles.

Location

This is something that is often overlooked to the headache and frustration of many would be miners. These machines are loud and hot. You essentially have an electric heater that also uses an industrial fan to keep it from melting itself. This space will need to have the electrical requirements as discussed previously.

So make sure you have a space that is well ventilated with a plan to exhaust heat, and bring in fresh dust free air. I say this as using AC to cool the room will eat into your profits and may even make mining unprofitable. The noise issue is a consideration you can sort out depending on whats available. (garage, basement, remote building)

Both of these issues can be handled with hosting, which is further explained in the information section.

Internet connection

Some miner setups have the option to use wifi. It is advisable to use a wired connection where available. This will provide a more stable connection and ensure you are submitting the expected amount of shares which is directly related to your payouts.

Please note that mining uses a negligible amount of bandwidth, and will not affect your other internet usage.

Information

You can use this information in this post as a good baseline to get you going. In addition to this you will want to research network difficulty; this readjusts every 2016 blocks to maintain a 10 minute block time on average. While this can go down it generally increases.

Solo or Pool?

You can solo mine but this is essentially a lottery even as a large scale miner. Should you chose this you can check this out as a starting point. [∞ YH] solo.ckpool.org 1% fee solo mining USA/DE 250 blocks solved!

Odds are most of you will join a pool. I will only say that it is in your best interest to mine at a pool that pays transaction fees (miner rewards). Then you will want to consider the fees associated with the pool. When it comes to these pools you want them to be large enough that they are getting at least 1 block every Difficulty adjustment period. Larger pools will offer smaller rewards paid out more frequently, and vice versa.
3286  Other / Ivory Tower / Re: Bitmain controls close to 51% of mining hash on: July 10, 2018, 02:40:33 AM
I think it is Samsung that is planning to release "domestic" ASIC chips. If those can be incorporated into vehicles, then a fleet operator could run a mining pool to reduce his costs.  For example, a delivery company has a fleet of 1,000 vans, and they are in constant contact with the head office. Installing a couple of "domestic" ASICs would generate a bit of hash power from the surplus electricity generated by the engine. Multiply that by 1,000, and you could have an economic mining pool. Include aa leisure battery, and the miners could be run for 24 hours per day. Run this as a service for other fleet operators, or even individual car owners, and you could create a reasonable sized mining pool.

I wonder if I've got a domain name to exploit this. Smiley

Well I have no doubt that you will find a name to exploit the this,  Grin

The idea itself would put some hashpower out there; I just don't think it would be enough to be relevant in any way. Not sure how many you are thinking, but lets say you manage to set up 10 chips/vehicle. Depending on the quality of the design, you need about 11 vehicles approximately to match an Avalon 841, or 19 vehicles to match an S9. This is just based on chip numbers.

So even the fleet would be a drop in an ocean. So if you are only concerned with having hashpower that doesn't belong to Bitmain; it's something. The idea just isn't feasible as a profit maker in terms of FIAT.

Your red trust will never go away.

While selling accounts is not against forum rules, it is a shady practice.

Trust is subjective and any DT member who feels they can't trust this account because it could or has changed hands would rightly tag it.

This let's people know that this account may not be in possession of any person they may have dealt with in the past.

In the meantime you can "tap" who ever you trust to find quality posts. Whether they be board specific is between you and them. They can then PM you with a list and amount they feel the post deserves.

This will still require extra effort for you and your Mariners, but would be minimal.

This also ensures the full amount is given, without them being awarded to a middleman, and them only being able to provide half of those. (Not knocking the initial awarding)

If you are promoting your store for sales you should post this on the services board.

Can you clarify the warranty part, as far as I'm aware the bitmain warranty only applies to the original buyer.
3292  Other / Meta / Re: It is possible that banned account can be unbanned ? on: July 06, 2018, 10:57:45 AM
It's not impossible, but is improbable.

Your friends ban notice should have given a time frame. If  one was listed it was a permanent ban.

They can follow the instructions in the ban email, and can create an account only for the purpose of posting here to inquire about the ban.

Odds are that ends with someone here finding out they plagiarized a post, then promising to never do it again, and the ban remaining.
3293  Other / Ivory Tower / Re: Bitmain controls close to 51% of mining hash on: July 05, 2018, 10:31:11 PM
Unfortunately as far as miners go there aren't many new concepts available.

All they can focus on is efficiency, to try and make any waves in the market. This can go 2 ways depending on the climate people are living in. For colder arctic/subarctic climates you could get away with creating an efficient heater by using an inefficient miner design. This isn't far off from when I move my 741's into the basement to feed into my furnace air intake. This could even breathe life back into non profitable miners. Then there is the efficient miner that needs to use the least amount of electricity per hash, and this is beginning to flatline, at least until a company improves on the current 7nm chip designs.

I like the idea of popping a few chips, or even an entire miner into anything and everything you can. The problem is most items won't be able to handle many chips, making the added cost of the equipment undesirable when trying to convince someone it will pay off in the end. The concept will appeal more to the old guard of BTC as they still hold the decentralized belief near and dear; you don't find that much amongst the current wave of crypto supporters.

Unfortunately regardless of how much hashpower is created in this way, Bitmain can continue to produce an efficient miner to more than offset this new hashrate. The only comforting thought someone pointed out to me in discussion about a 51% attack. Bitmain has so much invested in BTC that it doesn't make sense for them to due any damage to the network. It is of little comfort but I'll take it.

Poetry.
That's how you write an argument.

Thanks.

There is an article that says Patrick Byrne from Overstock invested a lot of money in this coin. Is it true? This is a POW coin so the question is when did he make that investment? When it was on exchanges?

Not sure which article you mean, but yeah overstock is invested heavily in RVN. I believe they mined it super early on, they may have also bought some not sure. RVN has been on exchanges for months now.

You should PM the bounty manager with your findings let them decide what to do in that regard.

Moderators likely won't do anything as multiple accounts are allowed.

DT may tag the user, it's at their discretion. They may need more substantial proof.


Did you try following the transactions further to see if they wind up in the same wallet?

This is a realistic price for the coin at the moment.

The real purpose of the Raven blockchain is right there in the title of the ANN thread, Asset Transfer. We are waiting on the DEVS to test the Asset Layer and once they are satisfied it can go live. This is when the coin actually has value.

Currently what the miners are doing is creating a strong robust network, so that there is something secure behind that Asset Layer.

The problem right now is that there are so many miners out there who just mine for the profits that day. Nothing inherently wrong with that but with a high volume of coin generation per day it can really drive the price down. So, no RVN isn't dead, some of the initial hype of the x-16R algorithm has faded and there is a lul between noticeable developments from outside the community.

People just have to decide if you want to get in early in hopes of seeing the project go further, do you mine something established to get a fairly setamount unless you HODL ( and for how long), or do you go chasing the pumps of random "coins of the day"

Yeah it happened to me several times and wondered if i reported that post or not, the solution was to look on my history for the name of the user and the topic.
Don't know if it will be accepted by theymos since it isn't an essential feature but it is a good one essentially for big snitches Tongue

Snitches get stitches duplicate reports??

I think that a good idea in the meantime would be for anyone to view their own report history regardless of how many posts you have reported. I don't understand why there's a minimum for something like this that could prevent people from submitting duplicate reports and make less work for the mods.

I agree seeing your reports earlier on would be nice, I think I need another 30 or so then I can review mine which will be nice.

We had this discussion some months ago:
Indicator for "marked as reported" in the forum

Thanks for that, I didn't find it when I searched.
I guess it wasn't an idea that was worth implementing.
