The cost of the contract is a one-off payment. You will find the details about upfront costs and fees in the Terms of Service of your contract.

As soon we send out the coins, the transaction is within the blockchain waiting for confirmation. We can assure we send out the transactions with the proper fees but sometimes there are some delays in the blockchain. Unfortunately, we cannot accelerate this process from our end. Please keep in mind that some wallets only show the transactions once a certain number of blockchain confirmations have been reached.

All of GX Blocks products do not have a maintenance fee.

The GXB contracts covers all costs related to mining including, inter alia:

- electricity cost.

- cooling cost.

- maintenance work.

- hosting services.

A mining day usually starts at 00:00 UTC and ends at 23:59:59 UTC so your miners will mine for you 24 hours a day and act exactly according to your settings.

We have a number of scripts running, and there are numerous checkups that are being done, which even include checking some parts of the process manually, to maximize mining outputs for our customers.

Therefore, as a result of that, the time between two outputs can (and will) occasionally be longer than 24 hours. On the other hand, it can also be shorter than 24 hours. The fact is, you will receive a mining output for each mining day. 

Keep in mind that all of our mining outputs are daily and automatic, but the actual transfer to your wallet takes place each first 72 hours of the upcoming month.

Also, when you order via debit/credit card, your mining outputs will be held for 60+2 days. We do so because of fraud and security reasons. Once the two month passes, the full amount will be released to withdraw it in your personal wallet. 

For security reasons, we do not disclose the exact location of our mining farms. We are operating several mining farms that are located in and outside the Greek borders. Our location selection depends only on electricity cost. Low environmental temperatures are not part of our decision making, since we use liquid cooling methods. 

You are able to mine Bitcoin and various altcoins directly via our Smart GX Mining allocation page*. The availability of cryptocurrencies you can receive depends on the available coins we provide through our supported coins and wallets.

You must choose an allocation strategy for your GX contract in order to determine the cryptocurrency received for your mining output. If no allocation has been made, the mining output will default to the following for the given blockchain algorithm:

SHA-256 contract - Bitcoin

GX Blocks Smart Mining Advanced Allocation:

It allows you to get mining outputs in many different coins even if they are not mined directly by a certain algorithm. For example, you can get mining outputs in any other coin while mining with an SHA256 algorithm!

That is possible by mining the bitcoin directly, which is then automatically swapped to your selected cryptocurrency or stable coin by our algorithmic framework. The Allocation function is designed for customers to receive delivery of their mining results in their preferred cryptocurrency. 

It’s quick and very easy! As soon as we receive your payment your contract will be added to your profile, and you will start mining in the provided day of your mining contract. Depending on the blockchain algorithm you select and the associated mining service agreement you enter into, you can either mine native cryptocurrencies directly and even choose a specific allocation for them. The first mining output is record after 48 hours of contract activation, and then a monthly mining output will follow to your private wallet.

Remark: Every day of mining will be recorded and sent to your account in the first 72 hours of the upcoming month.

Please refer to section “When do I get my mining output?” for more details.

We do not control the market evolution and thus we cannot control the mining rewards. There are certain factors which may affect your outputs depending on the product you have purchased.

This is the way your mining outputs will mostly vary:

1. It may happen that due to the lower mining output, the global interest in mining the natively mined coin of your contract diminishes. This would mean a decrease in the mining difficulty, which would also have a positive impact increasing your mining outputs. Conversely, if difficulty rises, your output will decrease.

GX Blocks Energy is a hybrid company which offers Bitcoin Mining Contracts based on Cloud mining and Renewable Energy Sources. By combining the two sectors we are offering a scalable, eco-friendly and resilient to market conditions investment, with no hidden fees, electricity costs and contract disruptions. Our customers range from millennials, cryptocurrency enthusiasts to investment advisors at major institutions making purchases for clients.

To get started, please Sign up and purchase your total hashrate power of the GX Contract. You don't need any special hardware or software or even to keep your own computer on to do cloud mining, we will do the mining on your behalf. 

When purchasing a GX Contract, you gain access to the computing power from the leased dedicated ASIC Hardware (miner) for the purpose of cryptocurrency mining. Our contracts are of fixed duration and computing power without any ongoing or unexpected fees. The computing power belongs to you, as well as the rewards from the cryptocurrency mining for the duration of the contract.

You will be receive the selected Digital Assets on a monthly basis, depending on the Type of the miner you have leased.

GX Blocks mission is to provide to our users an all-in-one, user friendly, end-to-end solution that facilitates fast and easy access to cryptocurrency mining. Our facilities backed by renewable energy assets, contribute to create the ideal conditions for experienced and newcomer users to get engaged in the DLT ecosystem through a risk averse business model. That is why GX Blocks has developed a fully automatized mining infrastructure solution with mobile mining unit that can be connected directly to the power source. This allows us to always strategically position our Mobile Mining Units in areas with a limited access for development or difficulty to be connected with the grid.

Maximum energy efficiency.
Our GX mining concept allows targeted placement of our mining hardware units at sites where clean energy plants produce 24/7 energy which is required to run the miners. This way, we “cut” the energy fees and grid costs for the power used for mining. With this strategy, we achieve revolutionary, low electricity prices.

Cutting-edge cooling technology.
We will use self-regulating liquid cooling system specifically designed for the blockchain mining industry. This liquid is patent cooling system from 3M achieves a best-in-class energy efficiency by lowering the cooling costs by 80%. That is translated in 16-20% of the total power consumption of a mining unit.

True scalability.
  Mass production & scalability has been deeply embedded into GX Blocks DNA from day one. Our Mobile Mining Units use a wide range of standardized components that facilitate the mass production. Our investment in software is safeguarding our growth trajectory by providing the necessary means to operate a large fleet of MMUs. According to recent benchmarking studies, the centralization of hashing power in the hands of a few is a risk universally perceived as high by large- and small-scale miners. However since GX Blocks is able to “mine” a broad set of cryptocurrencies, our mobile mining units reduce this concentration of power, as well as the dependency on a single government (e.g. regulatory changes), single energy providers (e.g. energy shortages or rapid price increases) and single cryptocurrencies (e.g. crash of single cryptocurrency).

Supporting the smart grid.
Our mobile mining units are designed and built to operate at remote locations near energy sources such as solar plants, wind turbines or hydropower plants. Our mobile mining units can be integrated into a smart grid and flexibly take the load off of energy grids. 

The pivotal parameter for cryptomining is the electricity price, where rewards and the depreciation of hardware are similar for every market participant. For commercial miners, the cost of data center infrastructure is equally important. At GX Blocks we address both of these cost drivers with our concept of Mobile Mining Units: it is a modular, simple, robust and highly cost-efficient framework for any data center operation with the flexibility and standardized size required for a global deployment strategy.

Hash Rate - A hash is the output of a hash function and, as it relates to Bitcoin, the Hash Rate is the speed at which a computer is completing an operation in the Bitcoin code. A higher hash rate is better when mining as it increases your chances of finding the next block and receiving the reward.

TH/s (terahash per second) - this abbreviation represents computing power of your account and has direct influence on your mining results.

You also need to understand its effect on your capacity to mine the coins. Having good knowledge in hash rate can help you make the best decisions when you are creating you GX Mining Portfolio.

Defining A Hash Rate

In simple terms, a hash rate can be defined as the speed at which a given mining machine operates. Crypto mining involves finding blocks through complex computations. The blocks are like mathematical puzzles. The mining machine has to make thousands or even millions of guesses per second to find the right answers to solve the block.

In other words, to effectively mine a block, the miner should hash the block’s header such that it is below or equal to the “target”. The target changes with every change in difficulty. To arrive at a given hash (or target), the miner has to vary some of the block’s headers, which is known as a “nonce”.

Each nonce begins with “0” and is increased every time to get the necessary hash (or target). Given that the varying of the nonce is a game of chances, the chances of getting a given hash (or target) is very low. The miner, therefore, has to make numerous tries by varying the nonce. The number of attempts that miner makes per second is known as the hash rate or hash power.

Measuring The Hash Rate And Its Units

Hash rate is computed in hashes per second (h/s). Some of the common terms used include mega, giga and tera depending on the number of hashes. For instance, a machine with a speed of 60 hashes per second will make 60 guesses per second when trying to solve a block. Kilohash (KH/s) is used for 1,000 hashes, megahash (MH/s) for 1,000 kilohashes, terahash (TH/s) for 1,000 megahashes, and petahash (PH/s) for 1,000 terahashes.

The various machines used to mine different cryptocurrencies don’t have equal hashes. For instance, a mining machine for bitcoin has a different hash rate from that of ethereum. This can be defined by the different algorithms used by the cryptocurrencies as they don’t use the same amount of memory and computing to be mined.

Payouts are generated monthly, but you will receive your outputs only once they have accumulated to a certain quantity. These minimum mining outputs are set in order to avoid that customers pay multiple fees for receiving small amounts in their wallets

World Energy Demand Growth is increasing and will peak before 2030 due to unprecedented efficiencies created by new technologies resulting to stricter government policies on carbon emissions. Blockchain network is estimated to consume at least 133.1 Terawatts of electricity per year currently and will continue to grow. Investors entering the market have difficulties such as slow processes, difficulty in transferring capital, intermediaries, location restrictions and Power balancing alliances.

GXB Platform's advantage compared to other businesses is its contracts income diversity, which comes by generating growth based on the production of sustainable energy and by financially supporting projects on renewable energy sources and blockchain technology. GXB Platform offers also, the opportunity to the user to track in real time the overall status of the operations , participate in the overall progress of future plans and access our Web Applications Solutions.

Bitcoin Mining calculators are a popular way of estimating mining performance, along with the general explanation about potential mining scenarios. When evaluating the benefits, please keep in mind that mining, and using our service, is subject to a daily maintenance fee (if applicable to your mining plan) which must be deducted from the daily mining rewards. The results of cryptocurrency mining highly depend on the price and the network difficulties of the given cryptocurrencies that you are mining. Neither of those can be predicted, so each customer must make an independent decision about the benefits of cryptocurrency mining and, in doing so, should consider the risks and their own circumstance when choosing whether to mine.
