OK guys, I've been following this thread and I realized I could really use some ADVICE!
I'm pretty new to the mining scene, meaning that I just got into it. I started ordering my first GPU's about 3 weeks ago when ETH was around $350 but since then things have really changed...
Right now I'm mining with 5 nvidia GPUs 2x 1070, 2x1060 6gb and 1x 1060 3gb. I didn't overpay for these cards, actually I got a pretty good deal on them. Currently I'm mining ETH with ~130MH/s but after reading this topic it's clear to me that maybe I should switch, although it's not clear to me to what and why.... I check whattomine.com regularly but ETH is almost among the most profitable coins to mine, and even if it's not, the others are maybe about 5% more profitable.
Anyway, the thing is that I still have some GPU's that I pre-ordered (at a normal price of $320-$350) and I'm still waiting for them ( 5x RX580 8Gb) but after reading this thread I'm starting to have my doubts and thinking about cancelling these orders...
The most important thing to me right now (since I just got into the game) would be to ROI my GPU's as soon as possible. Ideally I should cancel my order for the 5 RX580's that I pre-ordered and should arrive in the next 2-3 weeks, and wait 'til august to see what happens to bitcoin and to the whole crypto market. However this also means another 3-4 weeks of waiting if I decide to re-place those orders again in august. On the other hand I see people here not recommending to buy AMD GPU's at all, since ETH mining will not be profitable very soon...
(By the way, returning those orders is NOT an options since they were ordered internationally and would imply a lot of costs)
So right now my mind is racing and I'm full of doubts if I should invest in another rig with RX580 or maybe in something else. I do have a limited buget for another rig, around $2000
An Rx580 that makes $3 a day, but costs $400 is a worse investment than a Gtx 1070 that makes $3 a day and cost $400.
You need to brush up on basic investment principles like value at risk, not just profit per day to GPU price ratio. Additionally, imo coin apperciation should be treated seperately when calculating rig ROI.
If I mine 0.1 eth a day, my mining rig made $20 (say eth = $200) that day. If I choose not to sell and the eth becomes $400, it's my investment portfolio that apperciated. NOT what my rig makes. If eth becomes $100, it's my investment portfolio that takes a hit, NOT my rig earnings that was cut in half.
GTX 1080 ti to the best of my knowlage has NEVER been under $699 on Newegg - and that's where they're at NOW for the bottom price "on sale" cards, I don't think the "market shortage" ever had a noticeable effect on them.
GTX 1080 did get a little bit of a shortage, but never completely ran out and the pricing didn't get jacked up a ton.
GTX 1070, GTX 1060, and RX 470/480/570/580 are the cards that have been getting hammered, and are STILL high on price and short on stock - though they are starting to drop SOME on pricing and availability seems to be seeing a SMALL improvement over the last few days.
1080ti was $659 on Amazon for a while. Gigabyte FE for $659 a few days. Then MSI FE for $669 for a few days. Following by Palit FE for $659. The Evga SC2 1080ti is $729 now. I have 2 of them, they hash at 970mh/s skein vs 930-950 for the FE cards. The FE cards are throttling slightly I think, 76 degrees hence are slower.
