Right now a RX 470/570 4GB if you Dual mine brings in exactly $2.20/day.
The 1080Ti mines ZEC at ~700H/s and makes $3.41/day.
Even though the 1080Ti is slightly more efficient, its should be negligible at these profits.
So the card costs triple, and only makes $1/day more than RX 470. How does that make sense?
Yes I know its very optimized in certain algos like LBRY or NXS or Skein, etc. However those coins have very low market caps and can easily crash in the near future. You can't depend on them for mining in the future.
So which is smarter...
1)
Buy RX 470 and make $2.20/day today
In 6 months make $0.50/day
2)
Buy 1080 Ti and make $3.41/day today
In 6 months make $0.75/day
Which one do you think will make you more money in the long run? The 1080 Ti most likely won't even be able to cover their depreciation when they hit eBay.
In my opinion the 1080ti rig will, depending on what you're mining. On ETH sure the 400/500 series cards are a better choice, but how long will ETH mining last? When you look solely at profits and not account for other factors like power usage I think you're doing a disservice to your argument. During the craze I sold all but one of my 480 rigs and out that cash into Nvidia rigs. (1070/1080ti) I now have a much higher hash rate on the equihash based coins I mine with a 10-15 amp savings on power. I pay .14kWh so I not only have to look at purchase price but annual power costs. I loose more profit keeping my AMD cards than I do going with Nvidia. Yes there's a higher initial entry price, but a lower total cost of ownership. So I rather buy once, cry once vs buy once and then cry with each month when the power bill comes in.
However I do agree with the overall premise that one shouldn't be buying any GPUs right now till markets settle and we know what the ETH team is going to do if you mine ETH. In my opinion there are going to be so many cheap GPUs soon that anyone who buys GPUs at inflated prices, even MSRP, are going to be kicking themselves.
Also where can you get 470/570 for $200? At a minimum you should be using $300 to reflect the current climate and accurately represent the situation.
Yes I am thinking long term and what do you think will be minable long term?
When ETH goes POS at the end of the year what is left.
ETC
ZEC
XMR
Add 2,500,000 GPUs to those coins and what happens to the profitability.
The RX 470 will be making $0.20/day, while the 1080Ti will be making $0.25/day. So it really worth buying the 1080Ti so you can make an extra 5 cents a day?
New coins? Most devs are greedy and most news coins are all ICOs. This isn't like 2013 when there was a new shitcoin released every day which was GPU minable.
You clearly are a for profit only miner and are only thinking about things from that standpoint...I however am not
I've ROI'd on my 12 rigs and I pay my electric bill out of my own pocket, so I like to do speculative/VC mining now where instead of fighting the crowd on a given coin, I mine various coins under the radar with lower initial profits in the hopes that the coin at some point pumps so I can take profit. This allows me to fill my bags faster and hit my target much quicker because I'm not constantly fighting the crowd/difficulty. In VC investing you may invest into 10 startups with the hope that at least 1 of the startups makes it big, so you make the money you invested into the failing 9 startups back from the 1 successful startup. Those 2,000,000 GPUs don't matter to me as they most likely won't be mining what I'm mining; I pay my electricity out of pocket so immediate profits don't matter to me; worse case I just shut my rigs down and take a nice vacation till things die down. Plenty of options if you have ROI'd and sitting on a nice portfolio. Only those with more money than brains will suffer.
Such example is I'm currently mining ZenCash and have already mined close to 1000 coins...the project started off rough but they've been posting regular updates, have formed a foundation and should have their complete secure nodes system released in a few months. Once the project takes off and everyone swarms in to start mining it because of a price increase/increased profitability and crash difficulty, I've already mined my coins and moved on to another coin. What's currently $4000 can easily become $20,000 if the coin hits $20, which I think is quite possible down the road....until then I just HODL
So in my case all I care about is power costs since I will be paying that bill not my coins. So for that I like to use Nvidia as much as I can and only buy open box GPUs from my local PC store or EVGA/Gigabyte cards on the secondary market as the warranties transfers with the serial...
To each his own when it comes to mining. My system works for me but it's not for everyone. I'm just waiting for the cheap GPUs to hit the market so I can pickup all the 1070s and 1080 ti's I can from all those with more money than brains as I'm sure you and others are...
