    And maybe someone can tell some guide fof dummies))

    To answer this I'll go backwards in what you asked.

    Yes it is mined in the same way as bitcoin with some alterations, bitcoin uses the hash algorithm SHA-256, while Decred uses Blake-256 with 14 rounds compared to the default 8 so it needs to work more compared to Blakecoin which also uses the default Blake-256. (This is a lite explanation as it's more complex but there will be a full doumentation that will be released when the mainnet is released by the devs.)

    For some guide right now (Again because there is no testnet/mainnet software and full documentaion) I would recommend using AMD GPUs as the software is more designed for their architecture but Nvidia is a close second but not recomended when getting a new card.
    I would recomend the R9 Nano at this time as it's cheaper than the fury from the stores i'm looking at and you get more performance for less wattage.

    but if you have a few GPUs arround or already have a close modern card in the last 2 years, I would use them/that until the next series come out later this year as they will cost the same and have a better performance/watt ratio to this series.

    Im thinking the nano aswell, but im struggling to decide wether to mine with it or just buy dcr instead, wondering which method will earn more dcr.

    From the little information of the amount of decred gets mined per block per day(s) I would follow this untill the testnet is available and there is a real world figure of output to benchmark against.

    For this example; if each decred is worth $0.49 and a cheap R9 Nano is $499 (not including tax and shipping)
    dividing .49 into 499 will get you 1018.3673469... decred so untill the figures comes out and is shown that you can get more than that per year by mining using a single nano excluding electricity cost,
    I say buy decred for now and maybe if you want to min get the Rx 400 series range of amd gpus comming out Q2/Q3 this year but if you want to start mining when the mainnet is launched I would get the Nano around now.

    Are u saying it could take around a year to reach 1018 dcr with a nano?

    Not really, as it's was a simple example as that is how much the nano cost in decred with the starting rate of $0.49 and setting a milestone in a year to see if you can get back the cost by mining as most people will mine 24/7 and profit mesure on a yearly basis.

    Many factors and variables of mining decred are the among to the performance of the card (giga hashes per second), the amount of decred per block, the difficulty level to mine, etc.
    Freedom2Choose here estimated on mining using very rough values to estimate a profit and jolan stated here that an nano is close to 2GH/s from early tests.
    So utill there are real world figures to use with the info that has been stated on the forums, my last post is what i recommend for now

    Nvidia hashrates are comparable to AMD hashrate at the moment and this algo has not received many optimizations. I would say both would be good to buy & mine with, its just a matter of preference.

    I think its better to wait for testnet so we can get a more clear picture?

    Actually, they are the best. Keep them and mine.

    Hi,
    I have been reading on the forum but at the end i had to create a account myself :)

    Would like to ask about if there would be any relevance in this article saying Nvidia is the way to go
    http://www.forbes.com/sites/jasonev...ocurrency-mining-crown-from-amd/#6ff98a91519e

    Would of course be much cheaper to buy a GTX 960 or something than a R9 Nano. The R9 is three times as expensive and use more energy. Compared to what you get out...i dont know?

    Is it possible to put in more GTX cards to extend if you like? AMD have crossfire or what it is called.

    Regards
    Rikard

    That article is from 2014, and AMD has had some advances since then. :) And right now, the code works better with AMD. That said, the 750ti is very power efficient. (That is why I own one, and may get another for my media PC) And nVidia is much better on Linux for all the other things you use a graphics card for. (Like graphics)
    So buy a card you would like to have when you stop mining... (If you stop)

    I'm sure that if someone with cuda expertise ported the ccminer for the Nvidia people who mine decred, then things would change very quickly.

    I have chance to buy second hand Sapphire R9 295X2 for about 500€. Any ideas how much MH can I expect from it?. I would assume it should be about 2x-2.5x more than R9 280x, but I might be wrong.
