assuming we get our Terraminer by next week. How much BTC we expect to make from each miner within 3-6 months. I have got some pretty decent offer to sell my miner for $20K thinking if i should take on that offer, any thoughts?

you are crazy to even thinking about this, if someone is seriously paying you $20K, sell it asap.

This box will not make a profit at $20k with just 15% increase per, at 1.6TH and $0.15kw.  If you change to 20% increase per and it's a money loser.  And this is assuming you start mining today, which you are not.

Given the wave of THs that are surely coming within the next 2-4 months, i would sell this asap and pocket the profit. I can guarantee the difficulty gap will be >20% when the first waves hit, hopefully afterwards it will start to flatten out but who knows.

Pleas stop typing so much hot air, and just show photo and video of your hardware working

1104  Other / CPU/GPU Bitcoin mining hardware / Re: Aliexpress - Deal or no Deal? on: January 30, 2014, 01:39:56 AM
I am a frequent buyer of aliexpress and I must say that there was only two times that I didn't receive my order as described and I got a full refund on both of them (on one of them I actually kept the product as well).

That being said I have learned to do my research when buying from aliexpress and read other buyers feedback and also check out the sellers overall feedback score.

That will help you decide if to buy a product or not.

EDIT: Also check out the seller's store and profile.

But yeah the miners on there (the cheap ones) are fake listings.
Q
There are some real miner listings but they are more expensive than buying it from the manufacturer.



The only ones worth buying are the cheap ones which are all scams, the sellers with good feedback and delivers price their miners way higher than ant miner price here on top of expensive shipping, so there is really no point.

Cointerra is offering 15% discount on next purchase for January and February Customers, Why in the fuck would I ever want to order anything from you again cointerra, go fuck yourself and send us our fucking machines.

sorry but this made me lol  Grin  was just reading their announcement and suddenly saw this at the end..
1106  Other / CPU/GPU Bitcoin mining hardware / Re: Aliexpress - Deal or no Deal? on: January 29, 2014, 07:39:39 AM
don't bother, aliexpress is a waste of time.

All the miners listed with low prices are scams, seller will give you fake china post tracking #, hoping you don't file claim/chargeback within the 30 days before aliexperess give them fund.

The legit sellers sell them way overpriced.

No free lunch.

look at their latest ad:

EASY MONEY!  

Such shady tactic targeting the clueless newbies,  yeah may batch at $6000 will be easy money...  Roll Eyes
1108  Bitcoin / Development & Technical Discussion / Re: Running bitcoind on Amazon AWS (EC2) help on: January 27, 2014, 02:27:05 AM
Aws has it's advantages, it takes away a lot of the security headaches and give a true global distributed footprint to any startup, allowing them to deploy nodes all over the world for fast access. Trying to do all that on your own is a nightmare.

But i really hate their pricing structure, nick and dime you for every little resource usage.

I am currently using linode.com, $20 a month true root access, no issues.
1109  Bitcoin / Hardware / Re: CoinTerra announces its first ASIC - Hash-Rate greater than 500 GH/s on: January 27, 2014, 12:33:19 AM
The real "pros" are usually quiet and come with everything ready to go and to prove itself.  It has always been that way in the car community and they build there customer base on "past experience" on other platforms or they have ONE thing they did that was never able to replicate, etc.  In the car industry I like being that quiet one but sadly no way I could ever build ASIC chips, could fund it but could not built.  Soldering is still a challenge for me LOL!

It cracks me up when all their bandwagon people have NO explanation as to why it didn't succeed.  Then out of left field the quiet giant rises and brings the pain with them.

Don't get me wrong Cointerra came out with a final product that does have some performance BUT it was nothing like it was originally hyped up to be.
Yeah, if they had set expectations lower this would be fine but they were saying they would have far lower power consumption than KnC, which seems not to be the case.  Seems like bitfury did a really good job optimizing power use considering the 55nm nature.

Bitfury underclocked their chips - higher clock more watts, just like gpu oc we all mess around with when young. This means  cointerra is already pushing their chips to the edge as 28nm(unless horribly designed) should have significantly lower watts than 55nm running normal. Yet it is almost on par and the hash rate is still only 1.7, they probably won't even achieve 1.5 if the chips are ran at normal clock.

Really not sure what is going on here, but from the newsletter with vague mention to pcb redesign for next release, my opinion is they fubar the current design horribly.   
1110  Bitcoin / Hardware / Re: CoinTerra announces its first ASIC - Hash-Rate greater than 500 GH/s on: January 26, 2014, 08:33:46 PM
i can't browse a website without tripping over cointerra's google ads, luring newbies to order may batch...just like the old bfl tactics.

This company is such a disappointment, behind all that hype, being a pro team, and polished newsletters. If you look at the actual content it's all bullshit, for the last 1 month they basically haven't done anything to improve the performance but drag time. Whatever they are releasing now is the same hardware that was already on the market last year, 28nm or no.  The whole point of having 28nm is the ability to hit 2+ TH and in one standard 20A circuit without tripping the breakers or burn down your house.  Cant believe those guys can say with a straight face - yeah just plug it into 2 separate circuits, no shit sherlock.

Fail on both watts + hash rate.

You might as well just ordered some antminer/bitfury and started mining 3 months ago, by the time the difficulty gets to the level where watt/gh difference would matter materially between cointerra and the 55nm, the boxes will be all obsolete anyway. And you would mined a lot more bitcoins with the 55nm if started 3 months ago, instead giving cointerra a 0% interest loan while they did the dog and pony show.

1.63TH/s and 1.72TH/s with power draw at the wall between 1900W and 2100W – typically 20% higher than our anticipated target of 1650W but still sufficient to operate in a typical US home (110V) plugged into two outlets on separate 15A circuits

What a joke...not even compensation

They know the buyers are so desperate for shipping they will take anything.

Why are we still bumping this thread and asking if it's legit or not. A look at the website should tell you it's a scam immediately.  We are not in the bfl/avalon era anymore. Time to wake up people...
1113  Other / CPU/GPU Bitcoin mining hardware / Re: Announcing NEW 3TH/s and 5TH/s 20nm Bitcoin Miners on: January 24, 2014, 01:44:00 AM
I wonder how many suckers blinded by greed they will hook, quite interesting actually almost like a social experiment.
1114  Other / CPU/GPU Bitcoin mining hardware / Re: Announcing NEW 3TH/s and 5TH/s 20nm Bitcoin Miners on: January 24, 2014, 01:41:07 AM
20nm already built

Website without a single photo of unit, chip, office, pcb design or company info

All names with the most generic first last and fancy photos are nowhere to be found online

If anyone falls for this you have no one to blame but yourself. You guys should know better by now.

Good god...... all those newbies flocking to bfl and miners that will never roi (or even deliver) after the article... like lambs to the slaughter.
1116  Bitcoin / Development & Technical Discussion / Re: Running bitcoind on Amazon AWS (EC2) help on: January 23, 2014, 04:41:19 PM
You can run this Go implementation of bitcoind with google app engine but who knows what the costs will be. It purposely doesn't include wallet functionaity though https://github.com/conformal/btcd the wallet is here https://github.com/conformal/btcwallet

interesting i will take a look, yeah i looked at google app engine first but it's not a true vps like aws and has limitations in place that prevent bitcoind to run easily without some major tinkering.

In the end i think a regular vps is still my best(economical) option to keep bicoind running 24/7. Something like linode that cost $20 a month and not have to worry about i/o limits etc...

havent been following the development, but last i checked i remember seeing end of feb as the delivery date.

did they lie?
1118  Alternate cryptocurrencies / Mining (Altcoins) / Re: Swedish ASIC miner company kncminer.com on: January 21, 2014, 04:09:29 PM
the major cause of price gap is still news-driven, which triggers demand, every price gap you can map it to a news release.  The difficulty increase affects btc price in a minor way, in that as it is more expensive to produce btc which gives btc a sense of higher worth, just like other commodities. But mainly it's news that drives btc.  

If the day ever come that amazon accepts btc...watch out Smiley
1119  Bitcoin / Hardware / Re: CoinTerra announces its first ASIC - Hash-Rate greater than 500 GH/s on: January 21, 2014, 04:04:54 PM
does anyone know when they reduced the price to $6k?  doesnt look like such a good deal then if the later batch also paid $12k.  I understand the dec orders got offered 2x.
1120  Bitcoin / Hardware / Re: CoinTerra announces its first ASIC - Hash-Rate greater than 500 GH/s on: January 21, 2014, 08:16:58 AM
antminer is at 1.9 btc for 190GH(after easy OC), that's exactly 0.01 BTC/GH.   cointerra is 2000GH for $6000 or 6.6BTC, that's ~ 0.0033BTC.  So the very first shipments from cointerra will have a 3X discount to the current market price.

Who paid 6.6 BTC for the first batch???

okie fail on my part, was the first batch not $6000 or btc/usd wasn't around $1000? i don't remember been a long time :/
