Rich

Antpool killing.  4  Blocks in a row.  DAMNZZZZZZZZZZ.  Back to back.  What are the odds of that?

403436   16 minutes   514   5,779.20 BTC   AntPool   303.46
403435   21 minutes   1061   9,651.40 BTC   AntPool   482.62
403434   31 minutes   211   861.00 BTC   AntPool   603.89
403433   32 minutes   1919   14,391.75 BTC   AntPool   905.88

and then 2 others within 1hr.  CRAZY! 

Just received my 4 batch 12 s7's, arrived in 3 days flat.
Just finished testing all 4 and I couldn't be happier. Another 18TH/s for slushpool and classic blocks 

Free S7 here I come with a couple of blocks.  =)   Let's gamble.  =)  

P.S I love the fact that SLUSH gives their members the ability to vote for the size of the BLOCK.  Why would we want to hinder the Block size by 1MB?  That is simply insanity if you've noticed all the delay and increase in fees for transmission due to the smaller block size.  

UPDATE - HIT 2 BLOCKS!!!  WOOT!,
UPDATE # 2 - A Ton more blocks after that.  Thanks AriesV10 for the heads up.  WOOT!

your are correct my bad.  I will edit my comment.

I edited my post.

This isn't ANY pool. Leave them all off the thread unless they're actively giving away S7s for free.

   this is       kano pool




not slush.  they have 50 ph so leave them off this thread.


My apologies too much thread hopping

Just to let everyone know that does any RENTING.

Slush's has not had a block in over 17hours.  As you know this is rare for 50PH/s.  This might be a good time to send some Hashpower over there.

Because posting once a day raises your activity level and in turn gets you a higher "status" for signature campaigns...

meh I dont mind it

His post count is over 600. I'm sure he's just making a point in disconnected threads.
Besides, what's the point in raising post count? This isn't 1992.

Do you really need to spam all the threads you can with this new diff copy paste ? Looks like to me you're trying to jump your post count ...

digital coin is pretty profitable..
the reason its not on the top of the what to mine list is because its flawed.

digital coin goes hours in really low diff. about 200M or so.. during that time a s5 or s7 can get 100s of blocks.
then it shoots back up to 2.5B or so and then you dont get so many blocks.

its kind of a hold coin.. you can put it on bittrex but im holding mine to see what happens.

Digitalcoin is --->not<--- one of the coins I see frequently bettering BTC.

DGC gets to the top of the charts yes, but in little flash moments, then it will go rest down among the unprofitable coins. DGC's rapid movement is probably due to automated pump and dumps. You would be holding DGC for a far longer time, putting the DGC into an exchange with a sell order at a high amount, HOPING for another pump and dump to come along in which it would trigger your sell order and you become rich (rrrrright).  It's a good solution if you have the ability to wait - IE, not have to pay the electric or rent. However, it also puts you at greater risk for your stash of DGC to vanish due to an exchange hack, or a crooked exchange op claiming a hack, or hardware failure without a proper backup etc... Just look at Cryptsy, or the questionable happening currently at iSpace.co.uk .... a hardware crash without backup and mined coins went !poof!

Peercoin, Bitcoin and Mazacoin are usually in the top 5 coins, Its gets a little more fluid and muddy with number 4 and 5.

As I've said before, There is not one coin that remains consistently above BTC, its more or less a random rotation around BTC, but there is a definite select few that are in the rotation. Those are the coins I've been following by randomly timed noting their position within the top 5, of which I'll soon make a 1 month chart, then in the future a 2 mo, and 3 mo chart to show which coins are consistent more in rotation around BTC, then develop a "round robin" mining / investment approach.

BTC is no longer the most profitable. BTC, however, is the most consistent coin for short term mining, IE: mine today, cash out today. Where as the others are mine today, place the coins into cold storage or in an exchange with a sell order and wait till it rotates back above BTC's value - which does not take long usually less than 48hrs - automatically cashing out that coin for BTC which then is far easier to exchange for fiat. Not to mention more secure in my case because I only use one BTC exchange to convert to USD, where as the other coins have to be exchanged on many other exchanges.... why have your personal and banking data spread all around the world? Not to mention that I do not store ANY coins on the web, they are all mined then transfered to cold storage unless placed on an exchange with a sell order.

Its just a hair bit more work than set it and forget it BTC mining, but for a 10%, 15%.... 25% or more increase in profit over BTC, its worth the few extra mouse clicks.

Mining is profit investing now.... not just mine and cashing out.

i tired for a couple of hours to mine from the ppcoind client on linux.. it always showed DEAD on the miner :/

i pointed my 2 s5s on here, each one has found blocks so far..

i think that is more then they would have found mining bitcoin and still a couple weeks left.

ive also mined on the digitalcoin one.. i found like 80 some blocks so far on that.

1 tank for 10 s7's in a stainless steel custom tank (leak should not be an issue) . . . when it's hot, it will get thin.

according to my research let's say a 100 lph pump in mineral oil it would be able to only pump about 30 lph.

yes need high flow pump due to viscosity, looking at triple 2000 lph pumps (adjustable) to circulate oil with jets at rad outlet into blades & the other pump will be sucking the hot oil behind the blades into rad's. the 3rd pump will be used to maintain/control flow of fluid from cold to hot or circulate within the tank for the up/down flow or as backup.

2*2000lph = 4000-70% (due to viscosity) = 1200 lph / 60 = approx. 20 lpm but i'll still minus about half of it for losses via rads, hoses etc still getting about 10 lpm flow rate. i could be wrong, someone to chime in would be good.

dual brand new sedan car rad's with fans.

might/might not remove fans, depending on the build but most likely removing them or replacing with the cheaper type of fans to assist in circulating the oil in tank.

looking into either phase cooling to assist in cooling or water chiller or tec but dual rad's with a cool room temp should be ok.

objective is to try to keep temps below 70 deg C, save some power from fans, each miner should be saving approx. 60W or more from fans alone so if it's 20 fans = 600W saved well still have to minus out the pumps & rad fans, but still should be able to save some power, dust free, dramatically reduced noise from 10 s7's per tank.

hunting for a small plastic container or aquarium to test on a single s7 & see how it goes. small test. i'm sure it'll work but in larger scale hmmmmm . . .

Immersion cooling is not for sissies. Its an industrial solution that uses industrial parts and systems for reliability and durability. If you are going that route, I would use a PLC to control and monitor the system. Low coolant level (as in a leak) shutdown or switchover to pump circuit B, monitor for primary pump failure  with auto switch over to the secondary pump, over heating auto shutdown, an messaging/paging/system alarm...etc etc.

Sounds overkill but in reality, what you spend for the miners is not peanuts, with the amount of heat that needs to be carried and disapated, are you really willing to trust some plastic 1/2 garden pump to run 24/7 for months on end... only to fail and have the oil at a stand still which then cooks your miners? All happening with out you knowing it?

Look for hydronic furnace pumps and valves. I would not use a USED automotive radiator, too much conductive water is trapped inside which will cycle through with the oil as neat little blobs which will attach to your miner circuit boards and short out the miners. Remove the AIR COOLING FANS, use pump to circulate the oil within the tank and a separate pump with fail over pump to pump the hot oil to the cooling tower or radiator with fan.

Just my 1/2 cent worth of babble.....

For oil cooling, the 1300watt is too concentrated not to use the fans and/or high flow pump....

4 x S7s = around 18TH++
