I think everyone is waiting to see what happens to BTC first. So depending on how the next few weeks pan out will depend on when or if GPUs start flooding the market. Right now everyone is waiting until after August 1st to make any decisions. If the price of cryptos start to climb again, I believe new miners will hang on to their cards. people who have ROI'd already have no immediate need to liquidate and have a bit of room yet to eek out some profits.

As others have already pointed out, mining is still profitable, just not as crazy profitable as before, but profit is still profit. If I invest $0.30 per card a day in electricity and get back $2.00 ($1.70 in profit) there really is no reason to panic sell quite yet, especially with all the hope out there that this downturn will soon correct. Not until profits dip under costs does this really become a concern. Eth price would need to go under and stay below $100 for some time for profits to start to really get tight.

Even if some people do decide to start selling their GPUs early on, I see two big factors keeping the prices up for a little while longer. One is a lot of people here have already expressed desire to start buying up these GPUs at slight discounts, probably also anticipating a return to mad profits once things blow over. Another factor is that a lot of Gamers worldwide are pissed off of miners buying up all the stock and waiting on prices to come down to normal levels so they can get the GPU upgrade they been waiting on but refuse to pay a premium. Once cards start to return to somewhat reasonable prices this pent up demand will need to be filled and will absorb a lot of the early sell off.

So I think we will need to ride out a period of at least a month or two of very low to negative profitability to start shaking out weak GPU hands and see any type of GPU tsunami.

The tsunami of selling GPU's will start not before the coming of new cards in the market, especially the AMD RX VEGA cards which are projected to hit the market right just after the August 1. I don't know if that is a good time or a bad one but if the new cards are not available in the market no one will sell their cards, 29 Mhsh on Ethereum still makes you 0.0007 btc daily so 6 of them makes you still 0.0042 btc daily and for miners like me that is a good amount to have daily. I don't care that the price is going down, I am sure it will recover so as long as I am collecting new amount of bitcoin everyday no matter how low amount I am happy.

Lol, these threads are hilarious, a lot of noobs crying now
It' s good lesson, nothing is that easy as it seemed a few months ago

I was hoping to see cheap GPUs popup, but they are all still expensive.

Makes me sick that a lot of sellers are still promoting these GPUs as very profitable atm. I'm doing max 3 euro per day with my 1080 Ti! 

My advice is to only buy more gpus with profits because soon they will be really cheap and widely available. You're paying a premium right now for the GPU's at current market pricing.

No chance I will spend 7k for a 2gh miner.  The iBelink is far more efficient, much higher hash rate for less money.  Baikal has missed the mark completely here. 

Which OS are you using Marvell?
I'm using nvOC, haven't played with the clocks on ETH yet.

Absolutely not a waste. My 1070 6 card rigs do 170mh on ETH @ 1200w.
Currently earning slightly more than equihash selling on nicehash 

I will eventually run them all headless and login via the lan to mess with them.

If your wondering why I went with E5-2660 V1 cpu's it is that right now they are the best performance vs price. I paid a little over $50.00 each for them.

The E5-2660's are half the price of E5-2670's and have ~ %85 of the performance.

Hi,

My account is  locked and the admins are not responding to requests to reset. This has been going on for a week.  I am moving my miners away from this site. They seem to be doing what wemineltc did and will probably pull the plug on their sites and steal your coin.  Warning to all.

This is just the beginning. Wait till the next batch of L3+s and more ship out and difficulty will probably be over 500k and 1m in a short time. Huge risk to buy those miners nowadays, it's either buy them shipped now (no shit Bitmain preorders) and possibly make some profit or hope difficulty won't grow exponentially and won't make your miner nearly obsolete when it arrives, which it will.

Just doing some catchup on my reading, since a number of us here at Phil's thread use Nicehash... pls read

@Marvell1

After running ETH farm for nearly 2 years now.... I learnt an important lesson, esp if you have 20-30 rigs farm.

Rule No 1 -- always under clock, and under-volt (modded ROMs for low power higher hash if necessary)
Your gear will last longer this way.
Substantial savings on power bill too.
You can manage the cooling solution better.

Rule No 2 -- never dual mine otherwise hell will break loose sooner or later.
Sure you get a few more bucks for the 2nd coin.... but the RX isn't really optimized for the 2nd coin in Claymore's list.
When the profitability is better, I usually get my non-RX rigs, like Nanos and 390s, to mine DCR, ZEC and others directly

Rule No 3 -- always use the best card for the best coin type.
While all my AMDs are ETH mining.... all my 1080tis are mining exclusively ZEC, because simply NVIDIA cards are very good for ZEC

All 12 x GPUs working now -- one riser was not snapped in properly.

According to Cryptomined's video, 16GB is recommended but that was for Windows.

He tried 8GB on windows and no difference.

So since I am using Linux, I used 8gb (4gb x 2) -- this board only have 2 x RAM slots.

The CPU is a small Celeron G3930 as recommended by Cryptomined.

This rig is on smOS Linux. Next few days, will try it on 1070s on nvOC Linux. Cant wait to see that running on my small NVIDIA farm.

Biggest challenge for this mobo I think is the PSU size that you would need to get things together stable without maxing PSUs.

I get about 1650-1880watts, and just under 8Amps to run this 12-card rig. I use a Delta 2400w server PSU kit.

Space, footprint savings is clear. But you save on CPU, RAM etc too. Perfect for my modest ETH and ZEC farms.

And lastly that sub-10ms share submit times.... that's the Dwarfpool node closest to me.... I suspect the hosting ISP is just next to my warehouse....  

Wow 6 MS accept time on your shares, major respect. I've always like watching how you can tinker with things and get them working better citronick. Wish I had taken more EE/programming classes in college 

One of the best comments I have seen on these boards for quite some time.  Very well said.

Huh? How do you figure that out?

Newegg was selling them brand new for $319 on Ebay before the boom.
I don't think it will be too long until we see them back down in the 300's and then even lower. Especially before 2019

Thanks for the reply, it's good to know what other's have done/are doing.


Was shooting for 100 GPUs no matter the cost...overall it's not a lot of money to this investor...just testing waters.


It's really becoming about the opportunity cost for me and the investor...



I have a question, how did you accumulate your 250 gpus?
