All About BTC, LTC, ETH mining as well as other alternative crypto currencies
A user called ghostlander on Bitcointalk has released a new optimized OpenCL kernel for the Myriad-Groestl algorithm that is supposed to give you at least 10% increase in performance compared to the public kernel available, but in reality the hashrate increase is much more significant. We have tested the new kernel with a Radeon R9 280X GPU and got over 31 MHS while with the latest sgminer kernel we have managed to get only about 10 MHs or with other words about 200% increase using intensity of 19. You can try to increase the intensity a bit more if your GPU manages to handle it ot squeeze a bit more extra performance as well over 19. So if you are mining a coin using the Myriad-Groestl such as DigiByte or Myriad on AMD hardware you should definitely consider upgrading the kernel (just replace the old .cl file with the new one) to get a lot of extra performance and increase your hashrate.
The last few days the exchange rate of Bitcoin (BTC) has been steadily going up and today it has surpassed the $270 USD mark and that may not be the highest point it may reach this time. So you might want to keep a closer look at how things progress, though unfortunately it seems that the peak in price of BTC is not affecting much other coins as Litecoin this time. LTC has been keeping a steady exchange rate for a while now at a little above $3 USD. The exchange rate for ETH/BTC is going down, but due to the increase of the price per BTC the USD/EUR rate for Ethereum is still keeping relatively stable, but low level. This market situation is resulting in miners looking for some alternative coins to try mining and maybe get a better profit instead of the more established or popular ones in the last few days. The results is clearly seen in some altcoins having temporary spikes like DGB or GeoCoin among others, so you might want to keep an eye on the altcoin market for other not so popular names as well.
The alternative crypto currency DigiByte (DGB) has shown a temporary peak in interest with trading on exchanges that literally skyrocketed many times over other coins that are more popular, but again this was only a temporary peak in interest and thus in the price of the coin. The interesting thing about DigiByte is that it uses five independent mining algorithms to process transactions over the network with each algorithm accounts for about 20% of all blocks discovered on the network. This allows for greater decentralization as currently three of the five DigiByte algorithms are ASIC resistant and much better for GPU miners. The best GPU algorithms to mine on are Skein, Groestl and Qubit and you can also mine Scrypt and SHA-256 with an ASIC if you already have one. The DGB coin is traded on some of the large altcoin exchanges such as Cryptsy and Bittrex among others, so if you are looking for something new to try on you might give DigiByte a go though in the next few days we are probably going to see it get back to the previous price levels.
