As an alternative billing idea, why not try the route of forcing donations, even for the basic usage of the application. Something like, for every 1 hour of web mining, you extend the usage for up to 2 days. That'll guarantee that anyone using your software will be forced to at least mine for 15 hours per month across your entire user base.

I think a few things will happen that might keep XVG profitable:

1) XVG will suddenly become more "scare" - hopefully that scarcity drives the value up a bit, which will make the existing and newly mined coin to be worth a bit more, which helps with the halving of block reward.

2) With the huge drop in profitability, people might just drop off entirely, deeming it not worth the cost / heat. That lowering in difficulty will help profitability a bit, but I don't think it will be a huge amount.

3) It's warming up in the northern hemisphere. People previously happy dual mining in the winter may no longer be happy about the heat generated or can't cool the systems sufficiently. Combine that with lowered profitability, it may get them to shut it off entirely. Additionally, some states in the US (and possibly other parts of the world) have higher electricity rates in the summer months to cope with increased demand. This could push profitability even lower for those dual miners, so again, point #2 - more people dropping out = slightly increase profits for the people that remain.

I personally will continue mining XVG. My power rate isn't the great (I live in Australia, so not cheap), but it'll still be profitable after a halving of the block reward (for now). It's getting cold here, so I don't mind the additional heat coming off the rigs as it helps to warm the house without extra costs for other types of heating. I'm planning to keep an eye on things  for the next few weeks to see how it goes, but I'm hoping you don't cease to support XVG on your pool, as it's by far the best out there.

That's not even logical. Claymore wants to blow up every single person's rig that is using Phoenix, just so he can get back them back to Claymore to pay 1% instead? If he really is behind Phoenix, he's better off taking 100% of the .65% for people that use Phoenix, instead of getting 1% of the 100% of people with blown cards who aren't mining anymore...

The logic behind that comment is really non-nonsensical.

I've never used Wattman, so can't speak to it (but I believe it's installed by default with drivers?), but I've never had a problem with overdriventool running and sticking. Even if it doesn't persist through a reboot, it'll be applied again before mining starts, so it'll stick one way or another.

If you're tweaking memory clocks / power settings, stick with Overdriventool. You can create a profile for each unique card, apply the appropriate overclock / undervolt settings, and then use the overdriventool command line + appropriate parameters to run in the same batch file as your Claymore startup file. This will apply the appropriate overclocks, and saves the headache of modifying the BIOS every time you have a simple change you want to test.

Turn up the DCRI higher - I run mine at 130 DCRI - 30.5 mh/s on eTH And 1300+ mh/s on XVG.

Is there a process I should follow when donating? E.g. message you my address and the amount I donated so you can keep track of my donation to my dashboard ID?

keccak seems interesting if you're already mining ethash on Nicehash, but I wouldn't mine Smart/Max directly (nowhere that I can find to exchange it thus far). I'm happy mining XVG and converting to ETH weekly using changenow.io

With dual mining slowly dying and Phoenix taking the ETH world by storm, any hopes in adding support for it? I love your work, but it's only half useful at the moment since I switched to Phoenix.

Also, do you accept donations in anything other than BTC?
