Shark Mining FAQ

Why Do I Want to Mine with a GPU Miner versus a Bitcoin Miner?

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 much more. These are considerably easier to mine with a GPU Rig compared to mining Bitcoin with a Bitcoin Rig. Altcoins can be 'traded' on exchanges for Bitcoin anyway if you desire.

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.

With a GPU Rig, you can select coins that are meant for the small guys like us, giving us an advantage by trading Altcoins for Bitcoins in a tech-heavy market for years.”

Can You Configure My GPU Rig so That I Just Turn It On and It Works?

Yes, one of the advantages of purchasing through 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, and within minutes you are hashing to your wallet. Depending on the pool you join ( etc ) you can adjust your payout amounts to payout hourly, daily, weekly etc to your exchange.

This is ideal for noobs who are able to move the crypto from exchange to wallet etc but can't build or configure their own miner and just want it done for them.

Why do your 6 GPU and 9 GPU rigs consist of several 3 GPU rigs, each with its own power supply, CPU, and motherboard? Why not make one big rig with 6 GPUs?

Our first rig models were equipped with 6 GPUs, one power supply, and one motherboard.

After additional testing and feedback from our customers, our engineers have concluded that this design has several major disadvantages.

Compared to mining rigs with one motherboard and one power supply, our mining rigs are better in several key areas:

1. Reliability.
A 1600 power supply that is used for 6 GPU rig operates under the maximum rated load or even slightly above it, so the power supply can deteriorate relatively quickly.
In our case, you will receive 2 1000W power supply, for a total power of 2000W.

2. Flexibility
If you connect a 1600W mining rig into a regular home power outlet, there is a risk to overload the electrical system, so the breaker will often cut out the power because the electrical system is already used at the maximum capacity, so you would not be able to connect any additional electrical appliances.
With 1000W mining rigs, you will have more flexibility, because you can place your rigs in different places at your home and the electrical system would not be overloaded.

3. Heat dissipation.
A smaller mining rig produces less heat, so you can place them more effectively and there would be no need to constantly run the AC to cool the rigs.

4. Shipping and transportation.
6 GPU rigs are very heavy and have a greater risk to be damaged in shipping.
If you are buying a 6 GPU mining rig, the changes that it would be bend and damaged in shipping are higher.
We ship all the rigs in industrial heavy duty packaging, each rig as a separate package, so there is no risk to receive a damaged rig.

How Long Will It Take for the Miner to Pay for Itself / ROI?

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, which beats the newest Bitcoin Rig by months and months.

Some people keep their mined coin 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 like to cash out daily, and with the right setup with Kraken or Coinbase, you can have your miner paying you daily cash to your real bank account / fiat money account.

Do You Offer Support If I Am Having Trouble With My Miner?

Yes, we offer support by phone, email and support form. We handle phone calls from 9a - 6p EST. Click on the Support Button at the top right to reach us!

What Is Your Return Policy on Rigs or Hardware?

You can find our Returns & Refunds Policy here:

What Crypto Exchanges / Wallets Do You Suggest?

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 Changelly, the lowest fee exchange for your top Altcoin trading at .05% instead of the usual 1% fee.

Do You Offer Discounts on Bulk Purchases?

Yes, we offer discounts on bulk purchases, please contact us via the support form with the details on what you'd like to do / how many of which product etc.

Should I use the special mining GPUs?

We do not recommend this because mining GPUs comes with only limited 3 months warranty and have no resale value as they do not have monitor ports.

I’ve opened my box, what do I do now?

Remove ALL the bubble wrap, tie wraps, etc. Make sure you can see the fan side on the power source from the top. Plug in a live internet cable to this socket. Plug your unit into a normal electrical 110V receptacle.

I didn’t have a wallet address but now I do, how do I put it in?

Call our toll free line, we can remotely access your rig with Team Viewer and help you put that in, it takes one minute.

I want to buy more, can I mine with multiple machines?

Yes. As long as you have a stable internet connection, and separate the rigs onto different receptacles, it will work fine. Most receptacles are on a 15 amp breaker, if the breakers shut off, you need to try different plugs in order to mine multiple rigs in that room on one receptacle.
