The advantage of buying a GPU Rig instead of a Bitcoin Miner such as the Bitmain Antminer S9 is that the GPU Miner allows you to mine Altcoins, such as Ethereum, Monero, Expanse, and many more.  These are considerably easier to mine with a GPU Rig compared to mining Bitcoin with a Bitcoin Rig and Mining Software is able to automatically pay you in Bitcoin when mining these valued Altcoins using Nicehash Mining Software.  You also have the option to mine the Altcoins such as Ethereum, Monero, Ubiq Coin and more directly to your wallet if you prefer this option instead of being paid weekly in Bitcoin.   Over the years your GPU Rig will allow you to mine the most valuable Altcoin at the time, by changing your pool settings in the config file, and even allows you a higher resale value because it consists of high-end graphics cards, motherboards, power supplies, frames and more that are easier to resell on the market than a Bitcoin Rig alone.  Also, a Bitcoin Rig will have a certain power or hashrate to it, and over time this power will hash less and less as the difficulty factor of Bitcoin rises, the Bitcoin Rig will mine less and be less valuable for resale simultaneously.  Eventually Bitcoin will become un-mineable where the only way to obtain Bitcoins is by purchasing them and therefore Bitcoin Miners will become obsolete where the other currencies that you can still mine for will become more popular. With a GPU Rig, you can select coins that can be mined that are growing in value such as Ethereum and hunders of others, giving us an advantage by keeping these Altcoins as they grow in value like Bitcoin started out or you can trade the Altcoins for Bitcoins in a tech-heavy market for years.  You also have the options to receive weekly payments of Bitcoin as your Miner is mining Altcoins.

Yes, one of the advantages of purchasing our miners is that if you prefer, we offer custom built Rigs with your wallet already setup in the configuration file. This makes our rigs turn-key in that you can open the box, plug it in, connect an ethernet cord or wifi adapter and within minutes you are mining to your wallet. This is ideal for individuals who are new to mining and would like their systems setup so they can power up the rig and start mining immediately without having to configure the hardware the mining software.

This depends on many factors including the coin you choose, the amount of hashpower that your rig has when purchased and more.  Most of our rigs will ROI in under a year and as new other Altcoins increase in value the ROI also increases. For example Ethereum has tripled in value over the past 6 months and other Altcoins such as Ubiq Coin gone from $.16 (May 2017) to $2.92 (August 2017) or Ethereum that has gone from $11 per coin (Feb. 2017) to over $440 (Dec. 2017). Customers will also use their Bitcoin from mining to purchase these Altcoins in exchanges to generate increased ROI.   A resource to determine ROI mining Ethereum for example can be calculated Here. Please contact us if you would like to know the estimated ROI for mining other coins. Some people keep their mined coins for a while, for example, they will hold their Ethereum for months and keep it in the exchange until they want to ‘trade’ for Bitcoin at the most advantageous time.  Others prefer to receive weekly bitcoin payments, and with the right setup with Kraken or Coinbase, you can have your miner paying you weekly Bitcoin or receiving other Coins which you can trade for USD or your select currency and deposited into the account of your choosing. If you would like to begin trading your Bitcoin or decide to sell it we recommend using Coinbase’s GDAX Exchange.

We offer a 100% Satisfaction Guarantee. If you run into an issue and need to return your Rig or Hardware you can find our Returns & Refunds Policy here:

You are welcome to use any exchange you’d like that accepts the Altcoin you are mining.  For most Altcoins, popular exchanges include Poloniex or Kraken. For Cryptonote coins like Monero, Bytecoin and such there is HitBTC.   For sending funds from an exchange to a wallet, we suggest using an online wallet such as Coinbase which allows you to withdraw to your regular / fiat bank account.  We currently also support GDAX, the lowest fee exchange for your top Altcoin trading at .05% instead of the usual 1% fee. Note that these fees may change over time and to please look review these crypto currency wallets/exchanges. Keep in mind most Altcoins will have their own wallets where you may have to download their wallet software for mined Altcoins to be transferred to, otherwise if you wish to receive Bitcoin the Nicehash Software will mine the highest value Altcoin’s and pay you weekly in Bitcoin to your Bitcoin Wallet.
