The Cudo Miner software is free to download. We take a 5% mining commission to cover operational and development costs so that we can continually improve the software profitability and features.
Cudo Miner will automatically mine multiple different coins and select the most profitable at any point in time. By default this converts all coins to Bitcoin so your value is held in Bitcoin. You can select other coins to earn in instead, so for example, if you’re a firm believer in the Ethereum project or you believe the value of Ethereum is going to increase and wish to accrue Ether as your chosen cryptocurrency, you can receive this instead. Then by default our software will still mine other coins should they be more profitable at the time and convert into Ether for you. This means you get the best of both solutions, the most profitable mining all the time as well as your preferred currency. The mining fees are normally at the same rate of 5% when directly mining for your chosen coin, meaning in this example you are mining Ethereum and getting paid in Ethereum. i.e. 5% but if we are mining the same algorithm we are paying out in, this rate may sometimes be reduced as there is less work for our platform to do.
There is a small withdrawal fee which is in the withdraw answer.
