my current is 0.16 cent(euro), besides this where the $1.5 is coming from, currently a 480 mining only etheruem with 0.1 cent electricity is making less than $1($0.9), you're telling me that with dual mining they almost double their income?
digging around, a 480 can only do 27MH on ethereum + 150 on pascal, that is hardly $1+($1.15 to be precise) no where near $1.5.... a 1070 can do $1.7 and has better density....
edit...seems that the 470 can do 29+150MH and the 480, 26 + 400MH, well this look better, but dual mining will not last, in fact pascal is tanking without limit, will follow same fate as sia and decred...
I'm talking about revenue, I always talk about revenue because everyone has different electricity cost. It's pointless to try and compare 'profit' when that number will always be different. For a 480, it has almost a identical power envelope as a 1070. That means it will be about the same, depending on your electricity cost. Of course some algos use less electricity, but that's usually peanuts compared to the overall revenue with the exception of Equihash on 1070s.
Not sure why you don't think it will 'last' any better then mining small coins with Nvidia hardware that are over saturated with Nvidia hashrate. The only reason altcoins are going up right now is because AMD users aren't mining Zcash anymore. All of Nvidia mining income right now depends on Zcash. There is too much Nvidia hash to be supported by the other altcoin algos like Lbry and Lyra2v2.
Ethereum and Pascal are not niche coins. Decred and SIA aren't niche coins. They're as mainstream as they get with the volume and market to show for it. SIA and DCR have been around for quite some time, you have no idea what you're talking about if you think they're going to magically tank faster then say Library.
If anything AMD mining profits are more likely to last then Nvidia as Nvidia is a niche. Our nice profits depended on obscurity, mining things AMD users aren't good at. Now that there are so many of us and there is so much Nvidia hashrate floating around, that's ruined. We generally have to mine the same things as Nvidia users once profit on coins tanks enough and it all equalizes with Zcash, which AMD also isn't bad at mining. There is no reason to buy overpriced Nvidia hardware unless a new coin comes along or some sort of optimization is made that makes Nvidia better at with a really big market.
