Seeing the cost of cards now has me tempted to dump my 5x 1070 and 6x 1080ti, still have the boxes and everything.
As far as coin price,I'm not at all concerned; they've always been moody.

It makes more sense to sell the cards and buy coins than to mine them... its always made more sense to buy them than mine once the difficulty spikes.

Sounds about right man. I paid $155 for my 480 back in October and after a few days of off and on mining I'm thinking it makes more sense to sell this bad boy for a tidy profit.
You have any suggestions on a good place to sell besides Ebay? I know I can do it here but guys around here seem a little indignant about paying a higher than new asking price for a used card.

Whats wrong with Ebay? Craigslist is another place or try reddit? The biggest markup will be Ebay though or maybe CL if you live in a large city.

I guess Ebay is ok but I don't have a high feedback rating as a seller. I get a little anxious selling such a high demand item on Ebay. Craigslist is a good idea. I've had some luck in the past selling on there. What is reddit? Is it kind of like Ebay or Swappa but for desktop gear?

Honestly, further price drops would probably be healthy not only to slow the insane difficulty jumps but also to cool down the crazy price jumps on GPU's and lack of inventory. I think the mining craze has really hurt availability/prices for gamers.

Just wait for the next gen of miners (aka vid cards) to hit the market, you'll be able to get 580's for $75 and people won't be able to give away 4xx cards.

Hm, I've just been using NiceHash so far, and I've certainly noticed a drop in overall gains. I wasn't sure if it was just from miners being added, but it seems like some of it may be related to the latest drop in price.
I noticed a fairly substantial drop on mine as well, around a 40% profit/mo drop. It's okay though, it's actually just barely under what my original prediction for profits/mo were when I built this rig, I had a solid month of mining at ~30% over original calculations, now it's like 10% under so I'm not sweating bullets or anything. Still on track to break even by Sept sometime, then it's all profits.

Yeah, prices tanked from profit taking I would guess. Healthy cool-down so far, possible buying time. Need to keep an eye on those ICOs though.

Just need a price increase before Vega appears

Haha, I'm banking on NV not taking as hard of a hit on the open markets for used cards, if I can resell these 1080ti's for even half what I paid a month ago I'll break even at end of July. I genuinely feel bad for the folks that will be holding on to 20+ AMD cards.

Interesting point. I could sell my RX480 right now for more than I paid for it. Problem is, then I can't play anything.

I think I'll probably just keep it as a secondary mining card after getting Vega.

Yup, timing is everything in mining hardware. As with the last 2 or 3 cycles you don't buy hardware at peak values. The price of entry on AMD cards was so low with 480 & 580 cards when the first miners got them they paid for themselves many, many times over by now, no need to feel bad for them.

Does anyone have a good source to really learn about this topic for beginners? I have seen so much information on it but very little in the way of explaining in laymans what it exactly is and how it works?

Unless you already own the hardware, we're way past the time when you should invest in new hardware.

This is likely true. Even if you're quick on the uptake, you've probably got a few days of reading to get everything pinned down, and you'll pay an exorbitant price right now to 'enter the game' as it were. You can get a way with a little cheaper if you go NV instead of AMD but you might want to just hold off entirely until the next card gen drops (and even then it may not be worthwhile).

Start by wiki-ing about bitcoin in general, and then google up some pages on things to consider, like electricity costs, heat generated, and a -> b -> c of mining (hardware, software, wallets, etc).

I'm just wondering if it'll get much better. To give you an idea, the calculations stated that I could pay off a card in a little over 3 months, but at this point, I'm looking at around 40% more time with around 127 days or more. (A lot of that is due to the drop in Bitcoin.) That's not necessarily a bad thing, but the issue is whether it will get even worse in the future. I've never really been a huge fan of the wary state of crypto-currency, which is what largely made me ignore it for so long after mining Bitcoins a few years ago.

Unless you already own the hardware, we're way past the time when you should invest in new hardware.

He can always consider investing directly in the coins rather than mining. The coins hit some pretty big lows yesterday (Eth at ~$220), and he already would've made ~$30 per coin if he purchased some yesterday.

That would be my suggestion. Still risky, but a lot less risky than mining right now.

I would suggest buying coins directly rather than mining at this point, especially since Eth/Zec/etc went down a decent amount from where they were.

And Eth had a low of $211 in the last 24 hours. If this bubble bursts similar to how bitcoin bubbles have burst in the past, it should dip to around $40.

When looking back at past performance (not always an indicator of future performance) the general consensus is to buy instead of mine.

However, for a few solid months this year, the opposite was true. If you had an investment in mining gear and could mine coins at a decent rate (when Ether jumped in price quickly, before the difficulty really spiked) you were actually making more Ether from mining than from buying.

I consider this time short time period an anomaly but still recommend both mining and buying. Mining more as a "hobby", to learn more about how Cryptocurrencies work, markets, exchanges community, fun etc. And buying some cryptocurrencies for longer term investments, or for trading if that's your thing. If you really want to get involved, obtaining the skills of learning a new programming language like Solidity will likely be a huge asset.

Right now, with the fluctuating price of Ether and the cost of building a decent mining rig, it's admittedly hard to see the forest for the trees. However, the fundamentals of Ethereum are still very strong even with the current ICO and scaling issues (problems that are being actively worked on) so I have little doubt the price will continue on an upwards trend over the rest of the year. This is mainly the reason I'm not selling any mining gear (or Ether).

I only sold some AMD cards to get some nVidia cards to "diversify" my mining rigs a bit. nVidia cards with a 50%-60% power limit and memory OC are very efficient at certain algorithms/coins.

Not a bad idea to diversify cards. I'm worried the about the downtime (between selling and buying -availability of NV cards has dried up). Hydro costs killing me, especially with AC on so I should probably unload some anyway.

It's looking like 1060's are hitting nice numbers with the new Ethminer release. Around 10% faster than Claymore with no dev fee. Can't wait to try this on my 1060 ghetto miner. Even 1050 Ti's and 1070's are getting a small boost.

It doesn't appear to be giving much, if any boost to 1080 and 1080 Ti cards per user reports. I get around 26 MH/s on 1080 and 37-38 MH/s on 1080 Ti cards (each card has memory OC'd, power limit 50-60%) on Claymore. Theoretically due to no dev fee it would still be worth switching over, all other things being equal.

It can be kind of rough during summer /w the extra heat I threw my main mining rig in the basement to address that issue. Now I only have 2 video cards heating up my main office.

Thanks for the feedback, did you notice any spike in CPU usage?
