We’ve talked about Bitcoins before, and even put together a list of 20 places where you can spend them.But a list of places to spend Bitcoins isn’t of much use if you don’t have any Bitcoins.Sure, you could go to a Bitcoin exchange such as Mt.Gox and exchange your money for Bitcoins, but there’s always security risks involved in doing so.If you decide to mine Bitcoins yourself, it’d probably take you forever just to mine one Bitcoin using an everyday computer rig.So, what’s a budding Bitcoin enthusiast to do?Well, if you’re serious about getting into Bitcoin, and don’t want to deal with the potential dangers of online Bitcoin exchanges, then there’s only one thing left to do: invest in a Bitcoin mining machine.These are purpose-built computers where the one and only aim is to mine as many Bitcoins as possible, as quickly as possible.Here’s a list of 5 machines that will be shipping in the near future.Make sure you have some cash to burn!There are three machine models in the Fast-Hash One series of Bitcoin mining machines: the Silver Edition, the Gold Edition and the Platinum Edition.

These are 19″ rack mountable Bitcoin machines, with the main differences being their expandability and the power of the included mining modules.All three machines come with one mining module, but can be upgraded to have six.The Silver Edition is powered by a 64 GH/s module and tops out at 384 GH/s.The Gold Edition is powered by a 128GH/s module, with a maximum hash rate of 768GH/s.The Platinum Edition comes with the most powerful 256 GH/s module, and can go up to 1.536TH/s.Overall, when fully upgraded, these machines will mine anywhere from 0.2 up to 0.85 Bitcoins a day.While the Silver Edition does not support expansion cases, both the Gold and Platinum Editions support up to six expansion cases, with each expansion case able to hold up to 16 modules, for even more mining power.The Fast-Hash One mining machines are available for pre-order.Price: $2,499 – 5,999 for base units CoinTerra’s TerraMiner IV is a water-cooled Bitcoin mining machine powered by CoinTerra’s own in-house ASIC chips, the GoldStrike I.

The TerraMiner IV is built on a 28nm process and comes in a 4U enclosure with a power supply included, which is a rarity in Bitcoin mining circles.The TerraMiner IV has four ASIC chips, and with each boasting a 500 GH/s hash rate, it means that the TerraMiner IV has a total hash rate of 2TH/s.At the current mining difficulty, that translates to just over 1.1 Bitcoins a day.CoinTerra also claim that the TerraMiner IV is power efficient, although there are no numbers available yet to prove this claim.The April batch for the TerraMiner IV is open for pre-orders.Hashfast’s Sierra is a high performance water-cooled Bitcoin mining machine powered by three Golden Nonce ASIC chips.It is built into a 4U rack mountable case and comes with two Seasonic power supplies built in.The Sierra has a nominal hash rate of 1.2 TH/s, which translates to about 0.66 Bitcoins a day as of the time of writing.The thing with the Sierra, though, is that it doesn’t have an on-board controller, so you’ll have to connect the Sierra to a main control unit via USB.

This main control unit can be anything that will run CGminer, a mining software.The Hashfast Sierra is open for pre-orders and is guaranteed to ship by March 31, 2014.Black Arrow’s Prospero X-3 is powered by 20 Black Arrow Minion ASIC chips built into a 19″ rack mount unit.bitcoin reward calculatorThe Minion ASICs are built on a 28nm process and are an in-house design.buffett bitcoin not a currencyThe Prospero X-3 will also have a built-in LCD display that will show statistics and diagnostics.bitcoin wifi sharingThe 20 Minion ASIC chips in the Prospero X-3 give it a hash rate of 2TH/s, good for about 1.1 Bitcoins per day as of the time of writing.litecoin coming to mt gox

The Prospero X-3 has been designed with up to 20% under- and overclocks in mind.It also supports the lightweight Stratum mining protocol.The Prospero X-3 is available for pre-order and is scheduled to be available at the end of February 2014.wts bitcoinThe KnCMiner Neptune is quite possibly the grand daddy of all Bitcoin mining machines.sell bitcoin amsterdamThe Neptune is basically four modular 20nm ASIC boards, designed so that the machine will continue mining even if one (or more) of the boards fails.The Neptune follows up from their previous miner, the Jupiter, which was built on a 28nm process.The Neptune has a minimum hashing speed of 3TH/s, which translates to about 1.66 Bitcoins a day.This is a vast improvement on the Jupiter, which was only able to mine 0.6 Bitcoins a day.KnCMiner also mention that they have the right to increase the speeds as it nears shipment, so the Neptune might end up being even faster once it gets into miners’ hands.

The KnCMiner Neptune is currently available for pre-order, and is scheduled to begin shipping in Q1/Q2 of 2014, limited to 1200 units.The following page reviews the best hardware available today in order to make some sort of a profit with Bitcoin mining.If you’re completely new to Bitcoin mining please read our “Is Bitcoin mining still profitable?” post before moving on.It will give you a good idea about the profitability of mining and will make you think twice before entering this very competitive niche.If however, you are aware of the competitive nature of Bitcoin mining and still want to get in the game, here you will be able to find the best Bitcoin mining hardware available.The good news is that there’s not many mining hardware companies left that make ASIC miners so choosing will probably be easy.That’s also the bad news.Even though many websites state long lists of Bitcoin mining hardware, only a handful of mining rigs can deal with the rising Bitcoin mining difficulty that’s out there these day.

Below is a side by side comparison of all relevant miners.Underneath the table you’ll be able to see a summarized review of each of the miners.Keep in mind that in order to see how profitable you can be with any Bitcoin miner you’ll need to make some calculations based on your electricity cost, the Bitcoin exchange rate and the increase in difficulty throughout time.Since not all of these variables are knows you will have to guess some as best as you can.88%Read review95%Read review81%Read review83%Read review79%Read review76%Read review70%Read review KH/s MH/s GH/s TH/s PH/s The AntMiner S5 is the entry level Bitcoin miner for someone who isn’t ready to part away with more than a few hundred bucks.Users who have purchased it seem mostly pleased with the device.However this is an outdated device and with today’s mining difficulty and decreasing block reward you won’t make more than 0.05 BTC each money in revenue.This means you’ll need to run it for about one year and 8 months to get a full Bitcoin.

Some customers also complained about the device being too noisy, but that’s just how a miner works – it’s loud and hot.Click here to learn more about the AntMiner S5 The Avalon 6 is a great contender for both S5 and S7 AntMiners.From the small amount of reviews that can be found online people are saying that it’s not nearly as loud as your usual miner and the hash rate is pretty reasonable.However at the current price tag I see little reason to choose it over the competition, it’s $100 more than the S7 that brings to the table superior results.Using the Avalon 6 you can make a revenue of 0.12BTC each month, hardly something to write home about at the moment.Click here to learn more about the Avalon 6 The AntMiser S7 was the raining champion up until a few months ago.Even at today’s difficulty levels and with the block reward halving you can still make 0.15BTC a month.It’s not a lot at the moment but if the Bitcoin price continues to rise it may be a profitable investment.

However I would’t suggest buying this rig due to the fact that it’s neither here nor there.It’s too expensive for an entry level device and it’s too weak to generate any substantial amount of Bitcoins.Users who bought the device seem generally happy with it however it was first introduced on August 2015, so it’s not that new.Click here to learn more about the AntMiner S7 The most advanced and most efficient Bitcoin miner today.If you’re serious about Bitcoin mining this is your rig.But since this miner just came out it’s possible that Bitcoin mining difficulty will now increase even more.At the current difficulty this miner can mine around 0.5 Bitcoins every month which makes it seem pretty profitable.However we did not take into account the electricity costs, pool fees and hardware cost.Not to mention the fact the difficulty can rise and the Bitcoin price can drop.It seems that even though this is the toughest miner out there, there’s only a small amount of time until it too will become outdated.

Until that happens though, it looks like a pretty reliable piece of equipment.Click here to learn more about the AntMiner S9 The Antminer R4 is intended for hobby mining – basically people who want to mine Bitcoins at home.Even though it can’t compete with the S9 it will probably be a good contender for the S7.The main advantage it has over other miners is the fact that it is has a specialized cooling unit that is much quieter than any other Bitcoin miner out there – since it’s made for a home environment.According to our calculations this miner should break even in about 12 months making it a pretty risky investment as most miners become obsolete after 6-9 months.However if Bitcoin’s price continues to rise this miner may yet yield a good return on investment.Click here to learn more about the Antminer R4 The avalon 721 (or Avalon 7 as it is known commonly) is the latest Bitcoin miner supplied by Avalon in late 2016.It has a lower price tags than most of the advanced miners but is also less powerful.
