Bitmain’s Equihash ASIC miners Z9 mini as well as Innosilicon’s A9 ZMaster are apparently being shipped and are getting into the hands of some users already. This essentially makes mining Equihash with GPUs pointless and not very profitable, so ZCash (ZEC) is already in the territory of ASIC miners, but not all of the crypto coins that used Equihash are going to just move from GPU mining to ASIC miners. Bitcoin Gold (BTG) for example is going to switch to a new proof of work algorithm they call Equihash-BTG which is essentially a modified version of the Equihash algorithm that will not be ASIC mineable.

Equihash-BTG is essentially going to fork to a modified version of the Equihash PoW algorithm with parameters that will require significantly more memory thus making ASIC miners harder to be made for it and no so efficient. We have already seen that with ASIC miners having a higher memory requirement makes it not impossible, but more like much less efficient performance wise if we consider as an example the Bitmain Antminer E3 ASIC miner for Ethereum’s Ethash algorithm. So Bitcoin Gold (BTC) will not become ASIC resistant forever with its algorithm change, but it will be safe for quite some time at least as we all know when there is an incentive (a lot of money involved) nothing can stop the ASIC miners.

The change of the PoW algorithm used by Bitcoin Gold will become active with a Hard Fork, though there is still no information or a planned block number or date when the fork will happen. So for the moment BTG is still using Equihash and can be mined using ASIC miners designed for this algorithm, but when it switches to the new algorithm it will be GPU mineable again and hopefully it will be still worth mining it by that time.

It has been a while since we have seen an update of tpruvot’s ccminer fork (source), but there it is now a new version 2.2.6 that comes with support for the new PHI2 algorithum for Luxcoin (LUX) that has just forked from the old PHI1612 as well as support for the new Allium algorithm for Garlic. There is an official binary release compiled for Windows available for download, do note it is a 64-bit only and it has been compiled with CUDA 9.0, so make sure that you have up to date video drivers for your Nvidia GPUs installed.

On a side note, Mining Rig Rentals has also just added support for people willing to buy or sell their PHI2 mining hahsrate. So if you need more PHI2 mining power or want to sell your hashrate instead, then you might want to check it out as well. There are still just a few rigs available, but with demand there should be more appearing and if there is demand you can also make some extra profit leasing your rig(s) as well.

CryptoDredge is a new simple and highly optimized crypto currency miner software for Nvidia GPU mining rigs that supports just a few algorithms at the moment, but performance wise it looks very promising. It support the following algorithms: Allium, Lyra2REv2, Lyra2z, NeoScrypt and PHI1612 and requires Nvidia GPUs with Compute Capability 5.0 or newer (Maxwell or Pascal architecture). Currently Lyra2z support is only limited to GTX 1050 GPUs, all other algoritms should work fine on other Nvidia GPUs. Also have in mind that CryptoDredge is a closed source miner available only for windows at the moment and it comes with a built-in developer fee of 1%.

What caught our interest initially with this new miner is the claim that it is the fastest Lyra2REv2 miner, so we had to compare its performance with the most popular Lyra2REv2 ccminer from from Nanashi that most people still use when it comes to mining Lyra2REv2 on Nvidia GPUs. Well, we can confirm that we are getting around 15% better performance with CryptoDredge vs the same settings using the ccMiner 2.2-mod-r2 fork by Nanashi Meiyo-Meijin on GTX 1080 Ti. So if you are mining a coin using the Lyra2REv2 algorithm or are selling your Lyra2REv2 hashrate on NiceHash you might want to check out the CryptoDredge miner.
