A month ago we have shared our negative experience with Giga Watt’s Miner Hosting Services and we just wanted to update you on the topic and still warn you to stay away from their miner sales and hosting services. Our December and January batches of miners that we have paid for back in November last year are still not deployed and not working and up until a few days Giga Watt was still selling new mining hardware for who knows when to be deployed (they have apparently stopped). Our disappointment with their services continues and it will get even worse for sure and they are just delaying and delaying month after month…

The WTT tokens are a bit better, but our disappointment extends there as well. There is still no price-varying real market for renting the tokens (you cannot use the tokens when your miners do not get deployed for months already). You still need to rent out all your tokens and you cannot rent them all even at the lowest price, so you are losing on that as well… no matter how much tokens you get you can rent maximum about 70% at the lowest price or less if you increase the price. Recently the company has risen the prices for electricity with 20% “in favor of the token holders”, but nothing really changes that much, at least your tokens should earn you a bit more. So we would also recommend not to go investing in WTT tokens now.

There are already a few variations available of the CryptoNight algorithm and different coins are using different versions, so it is hard to keep a track of all and use a different miner for the slightly different version. The SRBMiner Cryptonight AMD GPU Miner might help you here as it pretty much supports all of the variations of CryptoNight for now for AMD GPU miners, for example the just forked IPBC that decided to go for Cryptonight UltraHeavy (CN Light Custom v3) instead of the regular V7.

Supported CryptoNight variations:
– Cryptonight
– Cryptonight V7
– Cryptonight Lite
– Cryptonight Lite V7
– Cryptonight Heavy
– Cryptonight UltraHeavy

SRBMiner is a closed source miner and comes with a built-in developer fee of just 0.85%. The run the miner you just need to do some simple tweaking of the config.txt file like setting the intensity (leave it to 0 for auto) and choose the right algorithm, then just set the pools in the pools.txt file (more than 1 pool to have failover support) and run the miner. The miner works on older and newer AMD GPUs, including the latest RX series, but you should not have issues with older GPUs as well.

The Cast XMR CryptoNight GPU miner for AMD RX VEGA 56/64 GPUs has just been updated to version 0.9.5 with added support for the CryptoNight Heavy algorithm used by coins like Sumokoin (SUMO) and Haven (XHV). The new miner version comes with 0.5% performance improvement for the CryptoNightV7 kernel that it also supports. You can also use Cast XMR to mine the old CryptoNight algorithm, though now with ASIC miners available you probably wouldn’t want to do it. You can use the --algo command line option to set the desired algorithm: 0 for CryptoNight, 1 for CryptoNightV7 and 2 for CryptoNight Heavy. As a reminder, Cast XMR is a closed source miner and comes with 1.5% developer fee included as a means to support the further development of the miner.
