Why Is A GPU Miner > ASIC 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 hash rate 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 Miner So That I Just Turn It On and It Works?

Yes, one of the advantages of purchasing through sharkmining.com 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 ( EtherMine.org 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.


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 hash power 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.

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.
