The DigitalX Mintsy service has been available for a bit already (currently in beta), but we haven’t checked it until recently when we decided to register and give it a quick look. It essentally combined multiple services into one with some nice features and also some integration with the Cryptsy crypto currency exchange. What you get at Mintsy is a service where you can mine with your own mining hardware, you can sell your hashrate ot rent from other users for mining various algorithms or you can purchase a contract for mining hashrate to mine SHA256 or Scrypt-based crypto currencies or with other words cloud mining. It is all integrated into a clean and useful interface with a user friendly wizard intended to help bnot so advanced users to get started. So far, so good… things do really look like promising, or at least until you take a deeper look and do some math.


We are going to be focusing on the Mintsy Contracts which are essentially giving you cloud mining hashrate for a limited time – 1 month, 3 months or 6 months. The contract price includes all fees, so you do not pay anything extra for maintenance for example, but still the process are a bit higher than you would consider them profitable and worth investing into. Here is a quick example, if you buy a SHA256 mining contract for 100 GHS with a 30 day duration you would have to pay $19 USD for it, but with the current market condition mining for Bitcoins you would be earning just about 0.0317 BTC or about $7.2 USD at the current exchange price. Longer term contracts and for more hashrate do seem a bit better in terms of return of investment, though they are riskier, but you would still end up a bit short on what you have paid and that is if the market conditions remain as they are at the moment. The good thing is that you have the ability to mine in a pool and a coin of your choosing and soon there will also hopefully be a market for contracts where you should be able to sell them to other users if you decide to get out earlier. The situation with the Scrypt mining contracts is slightly worse, so the return of investment there and the risk is even higher.

It is up to you to decide where to invest and how much if you are interested in mining contracts, but for the moment we do not plan to go for any of the mining plans offered by Mintsy. As for using their mining pools or using the rig renting or leasing functionality, there are also better and more advanced services focused on either of these available that we would prefer.


Nvidia has just announced their new GeForce GTX 980 Ti GPU, a model that should take the space in between GTX 980 and the Titan X both in terms of performance and in terms of price. The GTX 980 Ti is essentially a slightly stripped down version of the Titan X GPU with slightly less CUDA cores that are 2816 here and with a bit less TMUs – 176 units. The other significant difference in comparison with the Titan X is that the GTX 980 Ti comes with 6GB of video memory instead of 12 GB. The recommended end user price of the new GTX 980 Ti GPUs is $649 USD so it is significantly better priced as compared to the Titan X and considering that it should be showing a very similar performance it sounds like an interesting product not only for gaming, but for crypto mining as well.


So we are taking for a spin a single Nvidia GTX 980 Ti to compare it to the the GTX 980 and the Titan X GPUs using ccMiner 1.5.45 SP-MOD. Note that we are not using the latest version of ccMiner in order to compare the results in terms of hashrate on the other GPUs that we ran a bit ago. We’ve compared using the latest ccMiner as well and there is notable performance increase in some algorithms such as Quark, but for most others there is no significant difference. Just as a reference the GTX 980 Ti using the latest ccMiner 1.5.51 SP-MOD manages to provide a 23230 KHS hashrate for mining Quark, but as we’ve said there is not much of a difference with other algorithms. Other than that as you can see from the results the GTX 980 Ti GPU is very close in terms of performance as compared to the Titan X and much faster than the GTX 980. So if you are looking for a new high-end Nvidia GPU for gaming and crypto mining when not using your PC, then the GTX 980 Ti does seem like a great choice…


HashFlare is a new cloud mining service that we’ve just discovered, apparently a part of the European company HashCoins that manufactures ASIC miners. There is a bit of controversy surrounding the ASIC maker, but it has been available for a while and apparently has shipped some miners already with more available for pre-order. We have not tested any of their hardware miners, but their cloud mining service is something that we are going to be testing. If you are interested in their mining hardware we suggest that you read a bit about the company and their products released so far, as their upcoming products do not seem very attractive price wise at the moment. Their cloud mining prices do seem a bit more interesting though, but don’t expect them to be the best out there.


It is interesting to mention that the cloud mining service does offer Scrypt Cloud Mining at $9.95 per 1 MHS, something that is not worth investing at all at the moment in due to the very high price per megahash and very low ROI you can expect (less than 1 USD a month) due to the daily fee of $0.01 USD per megahash. The Bitcoin cloud mining hashrate prices do seem much better than he Scrypt ones, though we’ve seen better than $4.45 USD per 10 GHS with a daily fee of $0.01 USD per 10 GHS. Interestingly enough the service apparently also plans to offer Scrypt-N cloud mining powered by GPUs, even though that has not been profitable to mine for quite a while now and with the mother company having already announced upcoming Scrypt-N capable ASIC miners. So if you want to check the service out the only thing that is worth to go for is the SHA-256 cloud mining hashrate, and as usual we would not recommend to go with a large investment in a new service that has recently been launched.


We have already purchased 100 GHS worth of Bitcoin cloud mining hashrate as an initial test at the service just to test things and we have even found some promotional codes that can give you discount from the regular prices. So if you do want to try HashFlare you might want to use the promo code for 5% off for purchases over 250 GHS – HF15SMMR5P2 or 20% off for purchases over 2500 GHS – HF15SMMR20P2, the codes should be valid for Scrypt hashrate as well. We have paid for the hashrate with Bitcoins and as soon as the first network confirmation was received the hashrate was available in our account, so it started mining for us. There are alternative ways to pay for hashrate such as with wire transfer or a credit card also available aside from the BTC option. You can apparently also purchase additional hashrate with coins you have mined and have available in your balance, so you can easily reinvest some of the miner coins for more hashrate. Another interesting feature is the ability to select up to 3 different pools to spread your hashrate from a list of pools available, you do not need to add workers or to have registration in any of the pools available. Do note that apparently the poos you choose and the percentage of your hashrate available at each pool may apparently affect your mining profitability.
