8th Alt coin thread. Or what to do now that asics are all over the place.

fucking asics makers ruining everything, thank god for x16r

does raven have more exchanges?  I have a cryptobridge  I would like a few more exchanges

I see 5

https://coinmarketcap.com/currencies/ravencoin/#markets

yeah but I can't use


 https://www.qbtc.com/   daily total trades of 3,400,000 usd  pretty sure they are in China and won't let me join

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

https://crypto-bridge.org/  daily total trades of 663,000 usd is the one I have

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

these are really small



https://tradeogre.com/ daily trade total of under 180,000 and not sure where they are based
https://nanex.co/    daily trade total of under 75,000  and not sure where they are based
https://cryptohub.online/ daily trade total of under 24,000 and not sure where they are based

I too would like to see Raven on another larger (or even medium) sized exchange.  I do know that Cryptohub is based in Argentina and I have used them (some for mining on there pool, a little for trading) for over a year and they have never robbed me.  Still it's a very low volume exchange, although they do seem to be honest in my opinion.

yeah phill got to the nuts and bolts of it :

If you want to mine a high residential rates u either have to have super efficient gear which does not exist atm
of offset if with solar if you plan to go big.

Btw it nakes no sense to have 700 amps of power at 240 v if you do not have the ability to draw ot least 80 percent of it from the mains.  The power company would not install meters in the usa at least knowing how much you could potentially draw withoute knowing they can supply it withoute you taking out the whole blocks power lol.

when my 400 amp panel was added there was a 3 month delay becuase the needed city aproval for a new transformer.

Solar is the future for me though. I already have an order for 300 watt panels from china. 100 panels on my home roof , i think i can fit 120 max then another 40 to 80 on the garage. 

its quite cheap if you can install it yourself.  under 10k.

the only hold up is decideing weather to go with string inverts which i hat or micro inverters which is what i want.
adding those would add another 5k or more to the inital project but makes it easier to manage the panels long term m

[Elder III]

Yeah, if I was either younger or healthy again I'd be very keen on trying to install solar myself. As it is the installations costs are pretty crazy for the couple of quotes we had.

They are working on getting listed on bittrex(got the legal stuff about them not being a security done already) and will probably be listed soon,we cant really know the exact date because who ever subbmited request had to fill NDA also

I used to have a single 25 kVA pole mounted transformer feeding a 320A meter base at the house, which in turn had 2x 200A panels behind it, and a 400A meter base at my shop with a single 200A panel behind it.  The 320A meter base was feed via 350 MCM Al and the shop meter base was feed via 500 MCM Al.  350 MCM Al is rated for 280A and 500 MCM Al is rated for 350A.  This is at 90C btw, which the power company is allowed to use.

A 25 kVA transformer can only do about 105A (and peak loads up to about 140A or so @ 240V).  Around my parts most homes with 200A service have a 15 kVA transformer, and large homes have a 25 kVA transformer.  Really large residential homes have a 50 kVA transformer.  A large 50 kVA is still only able to deliver 210A or so on a 24/7 basis.  And once you get much past that, the 350 MCM Al wire running between the transformer and your meter base begins to become the limiting factor.

When I started consuming above 20,000 watts 24/7, I had the power company come out and swap my 25 kVA for a 50 kVA one.  There was no cost to me.  Where I live in rural Virginia, nothing needs to be filed or justified with the county, it is all just between me and the POCO.  I just called them up one day, and 20 minutes later an engineer was at my door step and I showed my power usage and he said yep, let's swap in a 50 kVA for you.

For residential service, POCO always size based on peak loads, so having dual 400A services from a single 25 kVA is ok, as based on their experience, they never see a residential customer coming even close to pushing the continuous rating of a 25 kVA transformer.

strange way to spec a system lol, I pull 20k from my house and another 40k from my detached garage which has business service, when you spec a system here , they send a designer out to determine your needs and send out the transformer and pole after the permit process is done.

I live in the city though, heavy residential are , so they have to do everything by thr book  

at sone point ill use all the available power we discussed that during thr interview /shrug

Technically correct, but transformer power ratings are more of a moving target rather than a fixed number because as long as the core is sized properly for the voltage swing and frequency the power throughput is entirely dependent on the temperature rise of the windings. Taken to the extreme, that means a nearly infinite amount of power can flow through a transformer if the windings are superconductors. I know it sounds crazy, and using superconductors for windings isn't exactly practical, but it's true.

Even with humble copper windings most utility distribution transformers are immersed in oil for cooling so they can take a high degree of overload for surprisingly long periods of time, particularly if the ambient temperature is well below 25-35C. Hell, one cheap way that utility companies can instantly increase a transformer's power rating is to slap some fans on it; good for at least a 25% bump in continuous load rating, as long as the higher voltage drop is permissible.

When I started consuming above 20,000 watts 24/7, I had the power company come out and swap my 25 kVA for a 50 kVA one.  There was no cost to me.  Where I live in rural Virginia, nothing needs to be filed or justified with the county, it is all just between me and the POCO.  I just called them up one day, and 20 minutes later an engineer was at my door step and I showed my power usage and he said yep, let's swap in a 50 kVA for you.

The willingness of the utility company to upgrade your distribution transformer very much depends on the particular company and municipality (and, of course, how much average power you have drawn or are projected to draw). In my neck of the woods you practically have to set the pig on fire before the utility will replace it for free, and while they will gladly upgrade it if you pay them to do so, that can take weeks for the paperwork or whatever to work its way through the various bureaucracies.

  this is pretty much to case with  us.

[KaydenC]

Can confirm. In Malaysia it takes 2 months just to pull 250A 3 phase power in. Meanwhile you gotta make do with the default 63A 3 phase.

for now I have been buying s9i's at under 550 from bitmain  and sitting on them

pangolin  is now touting a 33th 2150 watt  machine  that is under 0.066 watts a gh  the best claimed by anyone.


I would have preferred it to be 20 th  and do 1320 watts.

Those are good numbers but serms to me btc mining has never been more unprofitable now than its ever bern
im sitting on six s9s I bought last year, 14th units , I couldn’t even sell them with bitmain dumping thier T1s and 9is

I don’t think ill ever buy another asic, unless baikal comes out with like an x16 or lyra miner

Hmm they use 16nm finfet, not 7 or 10nm, yet achieved efficiency exceeding GMO or INNO's 7/10nm miner. Are they legit?

Should you buy this

yes if you have a place for the sound it is really loud
yes if you have low cost power
yes if it ships quickly------- I got the demo fast

unboxing

It has been moved to the solar array


I sold it during the big runup in december

I shot HagssFIN a pm about it today.

Some people have reported making a killing on it, especially in our current market Huh

[soothaa]

With my new job I've pretty much put my farm on full auto thanks to AwesomeMiner. Have all my rigs benched/groups appropriately and let AM profit switch to whatever YIMP pool is the most profitable and I'm taking the BTC payout. According to my graphs I'm doing just fine.. sure profits are low but my power is covered, loans are covered, and I can buy toys for the farm and write them off as business expenses!

If they're using one of the more recent upgrade process versions, it's possible.
They DO have a legit 28nm miner with efficiency that could argue with the Spondoolies SP20.

Also, NOBODY has 7nm or 10nm in production for a miner yet - eBang will probably be the first given announced plans, unless Bitmain or Inno switch to using Samsung for a fab.

Yep

BTC and LTC  are asic secured  and need serious money  to  own enough  to 51%  mine it.
This has always been my argument against pos.


MY twist on gpu mined coins  is the need  3 ready_made forks to be secure against a 51%  attack
they also need  their own algo and all 3 forks  waiting.


right now  we have 43,432,079,575 gh   for sha 256  based BTC maybe  really  50,000,000,000 gh

and we can divide by 14,000   or 3,571,428  s9's   that is secure    and hard to overcome
may cost 1,785,714,285  and 215,000,000 or 2,000,000,000  in gear to attempt  to attack BTC with a 51%


LTC is 305,534 gh or 610,000   L3+  at 300 each 183,000,000  add 17,000,000 total 200,000,000  to attack at 51%

so both LTC and BTC  are protected  by  $$$ in gear

BTC  more then 2 billion is needed to attack with 51%  also  the net worth of the coin is 143 billion

LTC more then  200 million is needed to attack with 51% the net worth is 5 billion










on the  new pangolin  I may will  get a demo  to do  some you tube videos

Zcash difficulty took a pretty big drop today. No clue why but I’m going to enjoy it while it’s here.

Zcash difficulty took a pretty big drop today. No clue why but I’m going to enjoy it while it’s here.

There are other equihash coins - might have been a shift to one of those.

Could also be some GPU miners pulling rigs due to low profitability, or shifting to other more profitable coins.

Could also be normal "luck" variation.

I suspect it's a combination of "all of the above" though.
