It’s quick and very easy! As soon as we receive your payment your contract will be added to your profile, and you can immediately start mining. Depending on the blockchain algorithm you select and the associated mining service agreement you enter into, you can either mine native cryptocurrencies directly or allocate your hashpower to other cryptocurrencies (marked with AUTO), and even choose a specific allocation for them. For example: 60% LTC, 20% BTC and 20% DOGE. The first mining output is released after 48 hours, and then a daily mining output will follow.
Top Questions
How does Bitcoin mining work with crypt-cfd
Are you mining for yourself?
Besides the fact that we ourselves mine with the very same hardware that we offer to our clients, our capital is limited. We believe that Bitcoin and Altcoin mining is one of the best ways to receive Cryptocurrencies, however, we do not want to “put all our eggs in one basket”.
Where is your mining farm located?
For security reasons, we do not disclose the exact location of our mining farms. As of April 2015, we are operating several mining farms that are located in Europe, America and Asia. Electricity cost and availability of cooling are important, but not the only criteria. See our Datacenters page for more information.
What coins I mine with each algorithm?
You are able to mine Bitcoin and various altcoins directly via our mining allocation page*. The availability of cryptocurrencies you can mine depends on the contract you have chosen.
You must allocate your hashpower 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 - BitcoinEthash contract - Ethereum
(*) “crypt-cfd Advanced Allocation” (special feature): 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 BTC while mining with an X11 algorithm! That is possible by mining the DASH coin directly, which is then automatically swapped to BTC by our algorithmic framework. The Allocation function is designed for customers to receive delivery of their mining results in their preferred cryptocurrency. We call it “mining BTC the smart way”. The same technique is also used to get mining results in LTC with a SHA-256 contract, etc.
How do your ether contracts work?
When you purchase an Ether mining contract, you buy a share of a GPU (“graphics processing unit“) to mine Ethereum. The hashing algorithm used to mine Ether is called Ethash (or Dagger-Hashimoto).
Ethash requires the so called DAG file in order to perform the calculations. This file grows over time, which means that more operations for each hashing operation need to be performed. This means that the effective hashrate decreases a little each time the DAG file grows.
This has to be considered when comparing the theoretical output of your hashpower. Online calculators do not take this into account.
Also, please keep in mind that some of our products have a maintenance fee attached.
What are the expected returns?
Bitcoin and altcoin mining depends highly on the prices and network difficulties of the Cryptocurrencies that you are mining, which cannot be predicted. It would not “look right” if we would provide data on the mining performance and sell contracts at the same time. Therefore, we recommend all our clients to do their own research and do their own performance calculation.
For example, you might want to have a look at coinwarz.com. Remember that some of our products have a daily maintenance fee which must be deducted from the daily mining rewards.

Isn't buying hardware cheaper?
On the first glance one might think that buying miner X is slightly cheaper than hosted mining. However, there are a number of “hidden” costs related to purchasing and maintaining a miner that change the economics significantly:
Shipping costs: few merchants will cover this, but in most cases they will charge you extra.
Customs dues / VAT: if it is an international delivery you will likely have to pay customs dues and VAT; generally this has a huge impact on the total cost of your mining equipment.
Delivery time: when you pay for your device you have to wait until the miner is packaged and shipped; if it is held up in the customs this can take weeks. And during that time you cannot mine at all (“opportunity costs”). You have to wait and hope. And if the merchant has a stock shortage; it is you who has to wait. Withcrypt-cfd you pay and get your hashpower immediately online. No delays!
Costs for additional equipment: when buying miners from larger retailers you often have to buy additional equipment like an extra PSU that matches the electricity specs for your country, control units and specific shelves to store them efficiently. This adds up significantly to the overall price for hashpower.
Setting the system up: when the device finally arrived you have to assemble and configure it. Beginners often underestimate the amount of work and technical knowledge that is needed to bring the device up and optimize its settings. People that used the first ASICs spend days and weeks on it. In monetary terms this costs you twice: (i) your time and (ii) lost mining opportunity.
Maintenance: hardware failures, outages and crashes could lead to downtimes between seconds and weeks. If your unit breaks you have to return it and start from scratch (by the way: check the guarantee time of your miner; it is often less than a year). With crypt-cfd you have a guaranteed uptime of 100%: in case one of your units fails another unit will be switched over and start mining for you the very same second.
Electricity: having the machines at home not only brings heat and noise, but also an increase of your electricity bill; an important factor that many underestimate. Please do not get us wrong: we do not want to discourage anyone from mining at home! We are often asked about prices and realized that many users do not know about all the hidden costs. If you compare the true costs, you will notice that our prices are very competitive. We want to provide you the best possible mining experience, so that you can focus on mining your favorite coins (and we take care of the rest).
Which pools are you using for mining?
We do not publish a list of pools we are using. Our main criteria for a good pool are: reliability, fee structure and reject rate. Going forward we will solo-mine a few coins (and pass the fee savings to our users!).
Our internal policy is: “be a good crypto citizen”. This means, that we will at least use two different pools (in some cases we use up to four) for each coin. This is to preserve the decentralized nature of the crypto networks! If we become aware that a pool is getting close to 50% share, we will switch away from it and use a backup instead.
What is the maintenance fee?
Some of our products have a maintenance fee attached. The maintenance fee covers all costs related to mining including, inter alia:
electricity cost
cooling
maintenance work
hosting services
The fee is fixed in USD but deducted from the daily mining rewards in the natively mined coin on a daily basis.
How can I mine different coins at the same time?
crypt-cfd allows its clients to mine different types of coins at the same time. You decide which coins you prefer and you can allocate hashpower accordingly.
Each mining algorithm is set up with a default delivery cryptocurrency. The crypt-cfd Advanced Auto-Allocation (in short “AUTO”) will apply to all cryptocurrencies which cannot be mined directly. In the user interface go to “Mining Allocation” and choose the hashpower allocation that is best for you. When you are done press “save allocation”.
Remember that the cryptocurrencies marked with (AUTO) are not directly mined, as mentioned in the “What coins can I mine?” section of this Customer Service page.
In order to get the mining output, please ensure to add your wallet address(es) to your crypt-cfd profile. Find out more details about how to add your wallet(s) in the next section.

Why is my mining output decreasing?
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. 2. If you change your allocation to any of the available AUTO coins (not natively mined), your mining outputs will be traded from the coin that is natively mined to the selected AUTO coin(s). Therefore, the exchange rate will affect your mining outputs. For any further questions regarding your contract, feel free to contact us via our web form or the “Contact Customer Service” section on your crypt-cfd account.
What are the expected returns
Since third-party calculators are a popular way of estimating mining performance, we have set up a Performance estimation tutorial on how to make your own calculations, 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.
Why is my allocation switching back to BTC (SHA-256)
The allocation is only reverting in appearance. Each time you click on ‘Mining allocation’, you will be sent to SHA-256 by default. Thus, to see the allocation for X11, Zcash, Ethash, Monero, or Scrypt, please click on X11, Zcash, Ethash, Monero, or Scrypt at the top of the page. You will be shown the correct allocation.
How does allocation work?
Every algorithm can mine only certain cryptocurrencies directly: SHA-256 mines BTC and BCH X11 mines DASH Ethereum mines ETH and ETC Zcash mines ZEC Scrypt mines LTC and DOGE CryptoNight-R mines XMR CryptoNightV0 mines XMC The other coins are marked with AUTO and they are not mined directly. In other words, mining outputs will be traded automatically from the mined coins to the AUTO ones at the exchange rate of that day.
The product is a monthly or yearly payment?
The cost is a one-off payment. In addition, some of our products have a daily maintenance fee, which is deducted from the daily mining rewards. You will find the details about upfront costs and fees in the Terms of Service of your contract.
What is the maintenance fee?

You will find the maintenance fee details of your chosen contract in the Terms of Service before the purchase.
Can I get a refund?
No refunds are accepted as stated in the contract.

Can I use my mining outputs to purchase additional hosted mining services?
Unfortunately, at the moment, that is not possible. We are working on an AUTO-UPGRADE option that you will find on your dashboard. Until then, you can accumulate your mining outputs in your private wallet, and then use them to purchase a new contract.
Why has my payment order expired
We only allow 30 minutes for the payment in cryptocurrencies to reach our wallet. After this period, the order will expire. Please try again or contact our customer service team directly to help you set your order manually.
Why is my transaction unconfirmed on the blockchain
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.
Why do I have less hashpower now?
This is probably due to some of your contracts becoming inactive. This means that the mining rewards are not covering the maintenance fee of your associated machines any longer, and thus your contracts have been terminated. Please contact our customer service team directly for further information.
