Topic: Mining difficulty increased? What's going on? (Read 3350 times)

Doesn't need panic.

 A lot of miners will switch coins when one gets noticeably more profitable than another - and many cards are quite good at mining both ETH and ZEC, so with ETH profitability dropping due to the combination of folks adding new rigs and hashrate + price has been DROPPING some since the ATH ballpark a week back, I suspect some have moved to ZEC as it poked a bit higher than ETH on profitability for many cards.

 This is why I tend to refer to a "basket" of profitable coins, which will keep their profitability close for the majority of cards used to mine them all with.

 GTX 1070 is a lot better on ETH than the GTX 1080 ti is, due to the GDDR 5X memory latency issue with ETH that hammers cards that use that memory type.
 It's WHY the GTX 1070 mines ETH at a HIGHER hashrate than the GTX 1080, despite having a quarter fewer cores and a tossup on clocks.
 GTX 1080 ti has enough more cores to make up for the memory - partly - but eats noticeably more power to do so.

 As of right now though, even the 1070 can still make better $ mining stuff other than ETH.

 For stuff like ZEC, the 1080 and 1080 ti are viable options - very close on hash/watt and pretty close on hash/$ even before the recent 1070 price climb.

 GTX 1080 Ti on ETH would be closer to 250 watts I suspect. Perhaps 200 if you drop the TDP but you'll also be seeing reduced hashrate by a bit.
 Might be more efficient though for those with high power cost.

why to spend nvidia mining power for eth if there are much better currencies for nvidia available?
e.g. for ZEC you make + 470 Sol/s with 1070 and ~ 720 Sol/s with 1080ti - from Sol/W the 1080ti is even a bit better there what i saw from numbers here in the board (have just 1070 by myself).

and i do not say the 1070 is worse, just to consider it e.g. for higher density per rig - of course it's harder to power / cool 6 x 1080ti than 6 x 1070

TIs use a ton more power like 200 watt and max out at eth at 37.5 or so

1070s are better as long as you can get them under 500

I would might even consider 1080ti as the 1070s are already hard to get and from price / performance you are very close with that cards and you get higher density with 1080ti in addition.

I did some epoch increase tests and found that my Pascal Nvidia rig was pretty much unnaffected, while the AMD cards suffer, though with my 290s not so much. It's going to be interesting times.

I'm seriously considering just selling and swapping over to 1060s and 1070s. They are awesome for hashrate vs. power and looks like the difficulty bomb isn't going to effect them much.

Can't wait to scoop up their gpus for 50 bucks 

difficulty is nothing new thing. its always gonna get higher . never gonna down. You already must understand this.

as long as ethereum rise, no problem for miners. For myself, if my electricty costs: 200$/month. and if i get 400$ profit from ethereum. its still worth!

Nowadays profits are crazy. This wont go forever i know, but mining still be here!

I think even if the difficulty of ETH rise 4 times, it is still profitable for most miners.

i am sure that the difficulty will be increase more like bitcoin mining. this is what you need to thinking before you start your own mining hardware and you should know this. i think soon the difficulty of the coins will be increase again and if finally you think that mining is not profitable again for you, then you need to stop the mining and don't mining again.

It will keep increasing for sure. The reason is very simple and I think I have mentioned it to many miners that the more people will come into mining industry the more the difficulty. It is simple maths that, if there is one miner in the world doing all the mining then finding a block for that miner is 100% true. Now, if we have two miners in the world then they divide the smart work to 50-50% profit. In similar way you are having thousands of miners now a days and it has broken down the share of hash rate to tiny percentage. So hope this will explain your question smoothly.

Actually I have seen cards on Ebay that are pre-modded for Ethash.

I would not call it fraud either , they would be getting exactly what they paid for and won't have to tinker with the bios or anything.
If they fail to understand difficulty, then that's their problem.

I intended that more as a joke, actually. 

What you are doing is plain fraud. Never cheat a newbie into believing something that is not,everyone starts from zero and never be an ass to take advantage of people who does not know anything.@ OP mining difficulty will keep on increasing and there is nothing you can do about that,make the most when you can and get out when you think that profit is not that good.

Promote a RX 470 with "custom mining bios" with adjusted memory straps on Craigslist and I bet newbie miners bite.

LOL...it's only going to get worse...

...if I was looking to get into mining right now....I would run.  There is no way you are going to ROI any equipment that is purchased at the current prices for a very, very long time...

Nvidia GPUs are selling out now too, the stock of 1060s is very limited and usually overpriced right now and 1070s are starting to do the same. I don't know if they will be able to put more in stock quickly or if it's going to be a repeat of AMD the past month.

Nobody will buy a RX 470 for $400 second hand when they can just buy a 1070 for the exact same price.

Of course we are seeing people switch over to Zcash, but better it be slowly like this than all at one time right?

Anyone here planning to hold onto their RX cards is fooling himself, why not get a free upgrade to 1070 while you still can? Dont be stupid. 

It's normal that the diff increase they are adding new gpu all the time there is no shortage of nvidia gpu  the supply is unlimited it make sense that the diff is rising
