By now there’s a good chance you’ve already looked at purchasing yourself one or two asic scrypt miners to replace your CPU or GPU mining rig.If you haven’t you can learn more about them here.They’re less expensive, don’t take up near as much space and won’t send your power bill through the roof, but is it profitable?With the expected increase in difficulty for many of the altcoins out there, can you realistically expect any return on investment or will you end up with an expensive paperweight?Are you better off purchasing altcoins rather than mining them?What does Litecoins stagnating price yet increase in difficulty mean for miners?There are several questions you should ask yourself before purchasing your asic miner.The first two questions are easy to calculate.Using a mining calculators – this one., a website that has useful features including a mining calculator and currency converter.If you plan on using a multipool you can expect slightly better numbers, but this is still a good place to being.

Using these tools you should be able to calculate the amount of coins you expect to mine, and if you can expect a positive ROI.Assume you have $20,000 to invest in an asic scrypt miner and here are your specs.What are some of the variables you should consider?While you can’t know the answer to these questions, that doesn’t mean we can’t make some educated guesses and calculate estimated ROIs in several different scenarios.Using excel combined with a mining calculator I was able to produce these projections.If you haven’t turned a profit in four months, there is little chance you are ever going to.Setting the difficulty at 21772 gives time for your asic to be shipped, arrived and set up as many asics are still only preorders with promised shipping dates.Looking at this chart, we can see that the mining difficulty will greatly determine how many coins you are able to mine, and so the question of ROI is that of difficulty increment and Litecoins value.In short, the graph confirms what we already know, but gives us some numbers to work.

What can possible miners hope for then?Can you make money mining?Looking back on history, we can see that when asic mining came out for Bitcoin, there was a huge leap in the difficulty for awhile before leveling back out.The truth of the matter is that the difficulty can double, but it takes an equal amount of hasing power to be added for this to happen.It would take double the hasing power to increase for the difficulty to increase by double.bitcoin mining pro pdfThe current network hash rate for Litecoin is 400,792 MH/s, or 400.792Gh/s and the entire scrypt base network hash rate is 1.573+ Th/s as of June 29th, 2014.bitcoin not ponzi schemeA miner with 1.2G/h mining power would only represent a .0029% increase in difficulty for Litecoin, but a hundred of these units would be nearly a 30% increase in hashing power and a thousand of them would be near 300% increase.bitcoin preis 2009

It’s not crazy to think the entire network hashrate will double, and with multipools we can expect to see this hash rate divided among the most popular coins, with Litecoin taking a large portion of this – right now Litecoin makes up 25.477% of the total network hashrate.Yes, you can turn a profit, but with the imminent increase in difficulty, your profit is more than likely too small to make the risk worth it.ethereum coin profitabilityAt the current rate of Litecoin ($8.83USD) you could purchase 2265 coins with $20,000.bitcoin bedeutungThat’s more than you’d expect to mine if the difficulty increased at a rate of 9% or even 8%.bitcoin anti money launderingBut let’s not forget mining is one of the best way to be apart of the system and that it is what keeps cryptocurrency decentralized and working.bitcoin atp

The best thing for investors is a mix of proof-of-work and proof-of-stake investing.In the end, you have to ask yourself two question.How much faith do you have in cryptocurrency and how risk adverse are you?Carter Graydon is not promoting nor invested in any ASIC Mining companies nor cryptocurrencies mentioned.Information provided in this article is not intended to constitute an invitation or an inducement to engage in any investment activity .bitcoin developer india linkedinWhile it is now considered too late for hobbyists without expensive ASIC processors to start mining bitcoins, many of the alternative digital currencies are still well suited for mining on your home PC.bitcoin php gatewayIn this guide, we’ll take you through all you need to know to start digging up a few litecoins, feathercoins or dogecoins without any costly extra equipment.

For the most part, cryptocurrencies employ either SHA-256 or scrypt as their proof-of-work hashing algorithm, but many of the newer currencies have opted for scrypt.Scrypt tends to be the more memory intensive of the two – however, home PCs with reasonably powerful graphics cards can still mine those cryptocurrencies quite effectively, as there are no dedicated ASICs to compete with – yet.Perhaps surprisingly, it’s still possible to use just your computer’s CPU to mine some of the digital currencies.This holds true, even if you have only a laptop with integrated graphics; though this may not prove terribly effective and is not a set-up we would recommend.Before you start mining, you will need a wallet to keep your hard-earned coins in (see our guide to storing bitcoin).A good option is to head to the homepage of the currency you intend to mine and seek out the download link for the default wallet app.If you would like to do more research into litecoin specifically, we have a guide on how to get started.

If you find yourself in need of help and advice, most altcoins have community forums, as well as their own subreddit.The majority of wallets are based on the original Bitcoin-Qt client.Be warned, though, that before these wallets are truly usable, you may face a lengthy wait while the coin's entire block chain downloads.Unless you possess specific mining hardware, there are two ways to mine cryptocurrencies: with your central processing unit (CPU) or with your graphics processing unit (GPU) – the latter being sited, of course, on your graphics card.Of the two, a GPU offers far better performance for the cryptographic calculations required.However, if you are making your first foray into mining and don't possess a souped-up gaming computer – a laptop with Intel integrated graphics, perhaps – it will still be possible to mine those altcoins, but at a far slower rate.The catch with GPU mining is that it requires a dedicated graphics processor, such as you may have fitted inside your desktop PC – the Intel integrated graphics cards found in most laptops are just not suitable for the task.

To keep speeds up to a respectable level, most altcoin miners build dedicated machines using motherboards that can house multiple graphics cards, usually via riser cables.Be aware, too, that mining digital coins is very system intensive and can reduce the lifespan of your electronic components.It's a good idea to make sure you have adequate cooling in place, keep an eye on those temperatures and keep hold of any warranties – just in case.Mining can either be a solitary venture or you can join a mining 'pool', where a number of people combine their processing resources and all take a share of the rewards.It can be helpful to think of mining pools as joining a lottery syndicate – the pros and cons are exactly the same.Going solo means you get to keep the full rewards of your efforts, but accepting reduced odds of being successful.Conversely, joining a pool means that the members, as a whole, will have a much larger chance of solving a block, but the reward will be split between all pool members, based on the number of 'shares' earned.

If you are thinking of going it alone, it's worth noting that configuring your software for solo mining can be more complicated than with a pool, and beginners would probably be better off taking the latter route.This option also creates a steadier stream of income, even if each payment is modest compared to the full block reward.Deciding which altcoin to mine will be something else to bear in mind, however, some pools, such as Multipool, manage this for you and switch coins based on profitability.A handy piece of software called cpuminer is the easiest way to start mining, but does require the ability to use the command line on your computer.The program can be downloaded from SourceForge and is available for Windows (32 and 64 bit), OS X and Linux.For the purposes of this guide, though, we are making the assumption that you are using the Windows OS.First, download the appropriate file for your operating system.The zip file can be extracted to anywhere on your hard drive, as long as you remember where it went.

A good idea would be to create a 'cpuminer' folder on your desktop.So, how to set up cpuminer with the parameters needed for your mining pool?Well, it's usually simplest to write a one-line script (known as a 'batch file' in Windows) to launch the miner with the correct instructions.To do this you will need the following: Now, open Notepad or your preferred text editor.Do not, however, use a word processor such as MS Word.Next, enter the script using the following formula (note that this method assumes you are mining a currency that uses the scrypt algorithm): start "path" minerd.exe - -url URL:PORT –a scrypt - - userpass USERNAME.WORKER:PASSWORD So, using the example details above, you would have produced the following text: start "C:\cpu-miner-pooler" minerd.exe --url stratum+tcp://pool.d2.cc:3333 -a scrypt --userpass username.1:x Save this file with a ".bat" extension; for example: "my-mining-profile.bat".Once the batch file is saved, double click it to activate the miner program.

Your mining pool will most likely have a web-based interface and, within a few minutes, the website should show that your mining worker is active.Now that you know how to mine with the CPU, let's have a look at using your GPU.For those that intend to mine with GPUs, or USB mining devices, cgminer is the program to use and can be downloaded from the developer's website – unless, that is, you're a Mac user, in which case you will find some unofficial binaries here.Versions of cgminer following version 3.72 do not support scrypt mining, and support for GPUs was removed in version 3.82.Therefore, the latest version isn't necessarily the one to download.Instead, seek out the version appropriate for your needs.Again, in this example, we are making the assumption that you are using the Windows OS.However, if you are using Linux or OS X, the command line arguments (ie: the parameters) are the same.Furthermore, the instructions below once again assume you will be mining a scrypt currency.Extract the software into a folder that can easily be found, eg: "c:\cgminer\".

Before going any further, make sure that your graphics drivers are up to date.Next, press the Windows key together with the "R" key, type in "cmd", and press "enter".This will open the command terminal.Use the "cd" command to change the directory to the one housing the cgminer zip file.Then, type in "cgminer.exe –n".This will list all recognised devices on your PC.If your graphics card is detected, you should be good to go.If not, you'll have research the steps required to properly set up your specific graphics card.You will now need your mining pool details, just as with the CPU mining section above: Now we'll make a batch file again, in order to start cgminer up with the correct parameters.In this case, the command structure is: Start "path" cgminer -- scrypt -o URL:PORT -u USERNAME.WORKER -p PASSWORD Start "C:\cgminer\" -- scrypt –o stratum+tcp://pool.d2.cc:3333 --userpass username.1:x Now the mining software of choice is set up, you will see various statistics scrolling across your command line terminal.

If you are using cgminer, you will see more information than you would with cpuminer.In the case of the former, you will see information about the currency and the mining pool, as well as about your mining hardware.If you're running cpuminer, you will only see references to blocks that your PC has solved; although, it does, at least, show your hashing speed.Good news for miners who own PCs with dedicated graphics cards: it is possible to run both cpuminer and cgminer at the same time.To make this possible, add a "-- threads n" argument to the minerd command.Here, "n" stands for the number of CPU cores that you wish to employ for mining.Remember to leave one or two cores free to control your GPUs, though.Setting minerd to use all CPU cores will mean that the CPU will be too busy to send data to the GPU for processing.For example, if you have a quad core CPU, try setting the "--threads" argument to "2" or "3".Mining with both GPU and CPU concurrently reveals just how much better GPUs are at mining than the CPU.
