CEX.IO Bitcoin Commodity Exchange Adding Trading Fees

cexio-trade-fee-introduction

The Bitcoin cloud mining service and exchange CEX.io has announced its plans on introducing trading fees on their exchange. Up until now trading there did not have any fees, making the exchange very attractive place to trade due to the large trading volume as well. The lack of fee was also interesting if you were using an automated trading solution as it could more easily realize a profit without having to take into account a fee when executing trades. It was expected that sooner or later a fee would be imposed as crypto currency exchanges usually do get their profit from trading fees.

The introduction of the trade fee should happen within two weeks according to the official information and it will be implemented in two stages. Starting with a fixed commission of 0.2% for everyone and and then a month later moving from a fixed to flexible fee between 0.2% and 0.5%, depending on the 30-day trading history of each user. It is interesting to note that the reason given for the addition of the fees is because the platform is currently preparing the necessary foundation for the introduction of US dollars trading on the exchange and apparently BTC/USD and USD/GHS trading pairs will soon be introduced. CEX.io has also announced their plans on soon introducing Litecoin cloud mining as well, though no date for that is yet announced and it could take some more time before they have the right ASIC hardware available to provide the mining power they need for that.

If you are mining crypto currencies using Nvidia-based graphic cards such as the very popular new GeForce GTX 750 Ti or other models you might want to check out the recently launched forum called CudaMiners. Since the forum is still very new there is not that much information, but it is more focused and you should be able to easily find help on Nvidia mining questions and problems and also keep up to date on new developments easier. The forum has a dedicated section for CudaMiner, the most used GPU miner for Nvidia CUDA-capable hardware and you can even find its author Christian Buchner (cbuchner1) posting in that forum as well. So do bookmark this website and keep an eye out if you are using Nvdia GPUs for crypto mining.

The New Gridseed Blade Miner is Almost Here, For Real This Time

If you remember the story from last month about an supposedly upcoming 19.2 MHS Scrypt ASIC based on Gridseed chips that was briefly put for preorder on aliexpress by a Chinese seller with not a lot of details, then you would be interested to read this exclusive information hat we just received. We just got some real and exclusive information and photos of the upcoming Gridseed Blade Miners from MinerEU.com, an official Gridseed EU distributor. It seems that the new Gridseed Blade Miner will be officially released next week and we already have some real photos and information about the specifications of the hardware.

The new blade miner will still use GC3355 ASIC chips, the same same as in Gridseeds USB miners. There are 2 PCB panels in each Blade Miner and each panel has 40 GC3355 chips, or you get a total of 80 chips on a single Blade Miner device. Each PCB of the miner has own power socket and USB port to control it, so it is like having two miners in a single package with. The official Scrypt mining hashrate is 5.2 MHS (2.6 MHS for each PCB), but we believe we should be able to improve that hashrate a lot as what we did with their USB ASIC miners by overclocking and modifying them.

We should note that apparently Gridseed is no longer advertising the new Blade Miners for use for BTC (SHA-256) or Dual Mode mining, instead they are intended for use for Scrypt mining only. Using these devices for BTC mining could create power and cooling issues and the resulting hashrate you could expect is definitely not worth it compared to what you should be able to get in Scrypt only mode… especially after overclocking and maybe voltmodding.

The new Gridseed 80-chip Blade Miner is equivalent to 16 Gridseed 5-chip USB miners, the official total hashrate is quoted as 5.2 MHS or about 65 KHS per chip, so there should be some room for improvement with overclock and possibly voltmod. The total power usage at default frequency should be around 64-70W for each panel or a total of about 140W per Blade Miner. The device should be compatible with the already available software miners such as cpuminer, cgminer and bfgminer with Gridseed support as it essentially uses the same way of communication with the computer as the smaller 5-chip devices.

If you are eager to get your hands on these new Gridseed Blade Miners, you can order from MinerEU now and expect a delivery probably sometime next week (deliveries are scheduled to start around April 8th). Due to limited availability at the moment, the new miners are not yet publicly listed in their online shop, the order link is intended for their resellers. You can see the official product page of the new Blade Miner on MinerEU’s website with photos and specs, link below. We are going to be ordering one of these devices to be able to play with it more and meanwhile we have been invited to test the new miner by MinerEU, so more details will follow very soon.
