Is that justification?   I don’t care if it’s 5$ a TH!   Still have S17 nightmares.

Just got a batch in of the S19 Jpro+'s and the suns of bitches have gone back to solder on heat sinks.   One arrived with a heat sink jingling in the case with a piss poor solder and chip guts on it.

Guess I'll find out, power'd up a couple weeks ago.

We've got another small spot that can handle 50 miners or so.   Its at 480/277 though and the S19J Pro+'s would plug right in and would cost very little infrastructure to speak of.

Yet I'm really struggling with buying miners at 27.5J/T vs the 21.5 for the XP's. 

My gut is telling me at the rate of difficulty adjustment for all this fucking hash that keeps coming out of the woodwork that you better be at 21.5 or better or your just going to get squeezed out.

Anyone put any spreadsheets together proving it?    Sure bitcoin blasts off who cares but I'm just not feeling it.

Well obviously those miners are operating in low ambient temperature.  Running the fans at 100% and low ambient definitely does not conserve power.  I find it hard to believe that bitmain couldn't optimize the fans as well if they were focused on a low energy firmware.
 

In theory this would be a win win if we hit wide scale adoption.   Drop in hash for efficiency netting a lower difficulty.   Oh wait miners would just add more miners.   

So I seen you can buy into late 2023 Bitmain can load of hydro future's like low $20's.   Not exactly inspiring.

Thankfully the sanctions actually increased Russia's bottom line otherwise they could have an energy surplus at a cost that nobody could touch.

I think there's still a shit ton of hardware coming online.   Has to be to even flatline.  Having a real hard time believing there's going to be a meaningful downward correction in difficulty.   Miner's are just going to eat the loss till the price recovers.   Or don't.      Can't shake the nagging feeling this is going to carry right to the halving which would make for some real entertainment.

 

I just find the maintenance on air cooled isn't acceptable.   Seems like no matter how we air filter they fill up with crap, fans wear out or just plain struggle to maintain temperature when its +30+

We're updating the farm infrastructure and aiming at one bulk lot of the S19XP hydro miners.  From that standpoint I hope bitcoin stays in the dump for a while yet.

Look at the listed companies.  Marathon’s stock has been cut to a 1/3.  Rewards cut in half and they must have took on a boat load of hardware at the peak of the market even at what must have been a decent discount.
The Fed hasn’t even really started QT and the everything market totally shit the bed.
Between inflation and the measures to correct it I have a hard time thinking this is even close to the bottom.
Nonetheless we’re in infrastructure mode and would love to fill it up with cheap gear!  
I’ve seen some $65/TH which is still high at this price.

100% SCAM.  Avoid at all cost.

Cutting off Russia from SWIFT would only hurt the U.S's strangle hold on U.S dollar for trade.   Sanction's only make Russia stronger and they can't seem to figure that out.
Russia/China will figure a way around the U.S dollar and I really doubt it's going to be bitcoin unfortunately.

Right now in northern SK I can climate control down to whatever I want easily and about 15 degrees C seems to work well and have been using the Vnish 60-62TH profile on about 20 machines and they have been rock solid.   

I have brains a go and got greedy the first go and landed at about 65 yet temps seemed really reasonable with the low ambient so I let it eat.    Made it about a week and one card went down,  by the end of the next week another was down and limping on the last.
Figured well this is garbage gear I’ll give it another go.   Lowered it to very similar hash rate and draw as my Vnish settings.
Ran rock solid for 2 weeks straight.  I thought ok this might be the ticket.  I wanted to like it!   Then boom.  Sum bitch lost a fan and was merrily tuning away for I’m not just sure how long loading up to 80 degrees then unloading it to a reasonable temp and then back up.
Still haven’t looked at the machine or thought about replicating why it didn’t shut down.
Nonetheless 3 more hash boards down.

So am I understanding it right Vnish.net is the real deal and Vnish-firmware.com is the knock off?
We put the Vnish-firmware on a dozen machines as a test and they are all on top of the leader board on my pool account.

But I might as well support the actual developer.   Well my wife is a Russian national so biased a bit I suppose.

5% every 2 weeks feels like a dead end road to me!

Yeah it’s dogshit firmware.   Fucking thing couldn’t even figure out it had one fan down and sat there tuning for 3 days and cooked 3 more hash boards.   Fancy interface though if you don’t mind feeding it hash boards!

Anyone know how I can get a S17 back to the factory firmware? 

If keeping hash boards in these things wasn’t enough I managed to brick a couple control boards!
I did a SD card flash and the lights went off and then to blinking like I’ve done many times before and then replugged it and now no IP and it won’t take a SD flash again.

Anyway to recover these?   They were working fine.   After doing 2 in a row I quit! 

I’ve seen March futures at 81/TH.  BTC hits the 20K’s we’ll start to see shit happen.
