Mining difficulty increased? What's going on?

[MetaMiner]

Hey,

For the past few days the mining difficulty has increased. I'm mining Zcash and the value went from 9$+/day per GTX 1080 TI to 6.5$/day.
Is this normal or will the difficulty continue to increase?

Thanks !

It'll probably increase as some eth miners likely saw the hashrate drop articles and panicked, switching to Zcash. It'll likely continue as ETH becomes less and less viable to mine on.

The hashrate drop for Polaris is largely overstated. My reported hash for seven cards went from 202.7 to 202.2 MH/s. with the new epcoh. I think it has more to do with the fact that AMD cards have been unavailable for a month now, resulting in large numbers of Nvidia sales which do better on ZEC than they do on ETH.

Doesn't mean it can still cause panic and cause people to switch algos. It'll go down over time anyways and eventually we'll see people switching over to ZEC anyways, as well as other cryptocurrencies.

Do a simple benchmark with Polaris on claymores. The drop increases as the epoch keeps increasing, so its 0.5mh between 129 and 130, it will be 5mh between 130-140 and 15 in 140-150 etc. In 6 months more than half of all Polaris owners will have switched to other algos.

Benchmarks are just an estimate. When I ran my own benchmarks on Claymore the figures were overstated. Claymore's benchmark for a 5 card RX 480/580 8GB and RX 570 4GB rig showed a 0.8 MH/s drop between epoch 129 and 130, from ~143.3 MH/s, at epoch 129 to 142.5 MH/s at epoch 130. The actual hashrate for the 5 cards was 144.1 MH/s and that was dual mining with DCR. For 7 cards, the actual epoch hash drop was less than 0.1 MH/s per card while dual mining. People also mine ETH with 1060's now at ~23 MH/s and 1/3 of the dual mining performance of the RX 570 4GB.

The difficulty bomb on ETH is causing miners to switch over as profit reduces, expect more in about 2 weeks.

That makes no sense. Mining ETH is more profitable than mining ZEC with the RX cards. Currently a single RX 570 4GB will make ~$150 a month on ETH dual mining with DCR.

On ETH alone it's $118

Compared to $92 mining ZEC.

It makes more sense than switching over because your hash rate will decrease in 6 months. 

The market probably just over reacted to the FUD and there is the Nvidia factor.

It's not a single issue.

Yep, and the biggest one being there are no AMD cards for a month now. Vega release is going to very interesting.

[phobosq]

Provided is not going to be paper launch, as usual with AMD lately. HBM2 volumes are limited, so I'd expect that all cards will be gone immediately.

Back then no one was mentioning about possible hash rate drop for RX cards. How does it work for HMB2 models? Will those have same issue estimating they will be profitable to use for mining?

Hey,

For the past few days the mining difficulty has increased. I'm mining Zcash and the value went from 9$+/day per GTX 1080 TI to 6.5$/day.
Is this normal or will the difficulty continue to increase?

Thanks !

same with 1070x6 farm + 1070x3 PC. nicehash.

profit was dropped about 25-30%.

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

[Juggar]

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.

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

[Elder III]

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.

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...

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

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.
