[ANN] profit switching auto-exchanging pool - www.middlecoin.com

[SimonG]

Anyone know anything about middlecoin payout address 1M3jtksp1upR33SX1VzeCfH5x9fc6zKykR? 500 mhs seems hard to believe. I wonder if it's a company and hundreds of gpus are running in the same building or if it's many different places all hashing to the same address?

It was confirmed by h2o that it's a legit user in China.

The user have actually posted here too. He or she owns a company with a mining-farm in China.

have any of you played with expiry and scan-time i was reading lowering them will really improve getting shares in and out faster with scrypt and it has my work utility used to be 100+ less then the hash now its same or more.
these seem to really work good for my 2x 7970s.
"expiry" : "12",
"scan-time" : "6",

I've worked with "5" for both, but I'll try your setting nows. I'm mining with just one 7850.

As per EUR or USD to GBP, yeah, I don't think there are any big enough BTC/GBP markets.
I've been looking at this the last few days and the cheapest solution I seemed to have found so far is:
1) trade out of BTC into EUR on Kraken for 0.2%
2) SEPA transfer to a EUR bank account in the UK
3) Use a cheap FX company to change into GBP (found these guys earlier: http://www.worldfirst.com/) and doesn't charge for transfers.

Sounds good no?

For all of you that are in the EU SEPA zone: use Bitstamp https://www.bitstamp.net ... fast, secure and easy to use with low fees.

I've used www.therocktrading.com, they also support SEPA transfers. You should also check does your bank accept SEPA transfers, I found out that my doesn't, still got the money today but paid 1% fees. SEPA fee is allegedly 1€.

By February 1st, 2014, all transactions will be made in SEPA system, all current national systems are expired (between banks inside the SEPA region).

For the guys that are running 100+ mh/s farms: are you running on 120 or 220 volt systems? I'm debating making the switch to 220 to lower the Amperage on each system and gain some efficiency.  What kind of amp load are you seeing for a 4 GPU (290 or 280X) system?

Anyone running a significant amount of hashpower is not using 120V.  My farm is approx 18Mh/s and I'm using 240V.  I have three phase power to my facility (600A total) though my PDUs are currently single phase only.

A 4-card 280X rig will pull around 1100W.

Seems like a very bad day today so far-

I understand that, I'm mostly concerned about the Amperage, not wattage.  Wattage will stay the same, voltage will increase, therefore amperage will decrease. Theoretically it should be greater than 2:1 reduction since the PSU's will actually gain efficiency at 240V.

Really? 2 of my miners are down and so far it's still looking like a good day so far..

What is your exact question?  Maybe I shouldn't have skipped lunch....

Yes, you will halve you amperage going from 120V to 240V.  Yes, your PSU units will run a tad more efficiently (like a couple %) running on 240V versus 120V.  As I stated, a 4 card R9 280X rig pulls about 1100W from the wall which equates to ~4.5A @ 240V.

Thank you for that.  My current 4 280x rigs pull ~10.5-11A, so the reduction is greater than 2.  That's what I was looking for.

Agreed, I had one card flipping shit on me today and still have a decent balance + unexchanged...

Reduction greater than two what? You aren't using 2x less power from your drop, the advantage is that you can use smaller cables to your psus, more power supplies from existing breakers, a few percent in efficiency.

If you read the sentence again, I'm referring to Amperage.  The Amps drop allowing you to do what you said, get more computers on the same breaker, etc.

^ why don't you move this to the mining forum?



also, was there a large connectivity outage about 10 hours ago?  my internet was also down (MCI backbone), but it looks like a big chunk in our hashrate was taken out around that time too.

I went from 4Mh/s to about 4.7Mh/s last night and today is on pace to pay about 20% less than yesterday.  No significant change to immature/unexchanged either.

0.034-0.035 BTC isn't what I was expecting for 24hrs of 4.7-4.8Mh/s of hashing power.  

Coingeek, I don't suppose it's possible to add minor lines along the x-axis, is it?  It'd be nice to be able to read the graph with better resolution than 24 hr increments.

Why dont you do something about it then .. With that hashrate on RPC you would have got .1BTC without doing anything lol

[Biggen]

I saw no such drop in hashrate from my mining farm to middlecoin.com.

that equals exactly what im getting with 1.65Mh/s the last days - about 0.012

I'm guessing by RPC he means http://www.ronpaulcoin.com/ronpaulcoin_downloads.php maybe?

I'm only running a 1.6Mh/s rig at the moment but my numbers on here seem very low today. I ran it for 1 full day and ended up with about .016BTC and stopped it to try another coin only to end up coming back this morning and trying again, after 4 hours im sitting at about 0.00028039BTC which isn't very impressive. Maybe I'm just mining the wrong pool, i dunno. Still have much to learn I can see...
