Was talking about this wallet :
https://blockchain.info/address/1Cz1pTK8GxsJqdHQrFLWh77WwYsyqyDX3k

the only known bitmine wallet.
That wallet holds less than half the known refund amount.

So what exactly are you proposing?

Are you doing it on purpose ?

The wallet holds 431 BTC and bitmine owes 172 BTC.
Maybe you got a different number.

431 - 172 = Bitmine still have 259 BTC left after refunding all of us.

NB. There have been a lot of move on this wallet. More than a thousand of BTC have been moved away this month.
So let's block this wallet now before they scramble everything.
Sorry, I thought the big number in the top right corner was the amount of owed refunds (why else would it be there?).
Only 200k in refunds seems quite manageable.

If they have ordered parts for $3M for cloudhashing / chip sales, it won´t be too long until refunds come through.

They just need to sell a few of those chips / contracts and everything should turn out fine.

Okay, lets hope they sell their cloudhashing contracts and chips fast. (Which are a good value for money in my opinion)

As soon as they have worked through their preorder qeue, they should be able to refund the rest of their customers.

Yes, but in the case of bitmine they will not have finished product lying around, they have parts and parts on order.

Nobody will pay as much as bitmine payed for these parts, and it is highly unlikely that anyone will be buying these parts at all.

Therefore there won´t be enough to refund everyone if you try and force them into bankcruptcy, which is what you are ultimately doing when arguing your case about Betreibung in front of the court.


All that I am saying is that this is not the best possible outcome for customers.

In america,  there are several types of bankruptcy.  There is the type of bankruptcy where you are supposed to liquidate and divide up everything for creditors(chapter 7).  And there is the type of bankruptcy where the court comes in and creditors and the company come up with a plan on how to pay everyone back (chapter 11).  bitmine would be served well under something like chapter 11 bankruptcy.  

I mean,  let's face it. their  business plan sucks.  They are selling chips at almost the same price per GH that you can buy most miners.  Their cloud hashing is competitive, as far as cloud hashing goes,  but no one makes money buying cloud hashing. Only newbs would buy it,  and they have no advertising, so how are they even going to BFL the newbs?  I'm guessing that there margins need to be cut in half if they are going to pull out of this (I'm guessing they are pulling a little over 100%-400% margin on those chips...) If there is a chapter 11 equivalent over there,  I'd think it would be in our best interest to get them in that ASAP.  People are not going to get their money back at all,  otherwise.

Nice going Bitmine!

1 cable of the Antec 1000w PSU melted.
4 modules were running on turbo-moderated.

Well, if you use turbo then that is your own risk.

Maybe the unit wasn´t cooled enough?

nope, using advanced settings is own risk.
Desk cooled with 4 3000rpm fans, was running at 42 degrees.

Huh, well normally you should be able to get a replacement PSU XD.

Atleast with cloudmining those problems aren´t yours anymore.


What is the ambient temperature where your unit is?

22 degrees.
Have thermal pipes attached to back of the desk,
for heat to go outside the window.

And how exactly did you realize it melted? Did it stop running? Saw smoke coming out?

Hm seems good.

At the end of the day these are still desktop PSUs, which are not really built for 24/7 usage, especially not under full load.

Might have been that you were just unlucky and got a bad one.

if you see CMD READ ERROR(s) in cgminer, 1 or more module(s) doesnt have power.

At stock speeds,  these things are already pushed beyond their spec, pulling 1100w from the wall.  Turbo pulls more like 1200-1500.  I'm surprised the psu let you go into turbo mode without shutting down.

Well I cant see cgminer output (don't have your modified firmware) but I suppose that someone would certainly see reduced hash rate on his pool and then by logging on the ccd that one module is offline.

No, 1000W is 12V power that it should deliver.

Obviously after some 10-15% losses it will be atleast 1100W at the wall.

I think for the modules it should be the opposite, i.e. 1000W - 15%

I mean the 1kW of PSU power is 12V power.

It is normal that it draws 1100kW at the wall.

Yeah,  I guess I always put 10%ish headroom between what I connect to my PSUs and what they are rated at.  I always assumed that everyone did the same. =)

It also depends on how the PSU manufacturer has built the PSU.

Spondoolies sp10 PSUs are "overused" by 20% and there are no troubles there, as the manufacturer has said atlest 10% more is okay.

My 3-module CC desk is running at 52-53 Celcius @ turbo moderate. Ambient temp is about 28-30 Celcius.
Hope nothing similar happens to it, because it's located in an office server room where noone watches.
Don't want to get the whole server room on fire  Shocked Shocked
