The mining difficulty by Jan 2015 is predicted to be around 235,263,000,000.  With that difficulty level, 50 T/H of mining power will get you a mere 3.22 btcs per month according to this calculator https://cex.io/calc.  All of the 1-2 T/H miners in use right now will be mostly useless by September-October of this year.

edited in:  2 T/H of mining power will make you 0.65 btc in September, 0.43 btc in October, 0.29 btc in November, ... 0.13 btc in January 2015.  I will correct myself and say that a 2 T/H will not be worth running by November instead of September.

You must've missed this 25 TH/s miner then:

I know I know SCAM, but fun when it lasted.   ::)

Holy crap. Seriously? I don't get it. Bigger and better rigs for better mining I guess but it doesn't last long. I want a long term investment!

The problem is the chips wont be getting much faster. 20nm chips is about as far as they will go for quite some time. My prediction is you won't see 10TH rigs till next year

25 T/H at 370 watts...lololololol...   one guy responded "how do you plan on achieving 25 T/H at 370watts? and don't be shy about the technical specs."  :D

50 T/H miner hm.. what about 1 PH miner :)

I don't want buy any rig for now, price is even high than buy bitcoin directly!

50th miner will not be cost effective because difficulty will be too high by then.

And not only that but what is the cost for this miner? 10 th at 15-20k retail? Even the manufacture cost 6-7k @ 200 billion difficulty doesn't make much back.

Now

Never.

As soon as there is electric price differentiation everywhere in the world.

Also, worst competitor of massive farms, is the hobbyists and people uneducated about ROI issues.

this.

What if we get to 1nm? Then all we can do is build ridiculously large rigs with loads of chips in them, so it has more hashrate.

I'm waiting for the farms to disappear near.

we won't get to even 18 in the near future besides the fact it will be too expensive.  On top of that difficulty would be over 1 trillion.

So what if it's too expensive? You know that all manufacturers price the devices too high, and its actual manufacturing cost is much lower?
They can simply use them to mine themselves, and literally grab the whole network.

When difficulty reaches about 15 billion which will be soon, that is close to the actual cost of machines now. About $600 per TH. If they cant make profit mining or reselling equipment capital spending on research and development will slow down or stop.  Alot of asic companies will disappear by the end of this year.

I bet we will stick to 28nm for the whole year.

Nobody achieved asic of 20nm so far.

The company shipping the most miners out now are still on 55nm too

Bitmain, sure.

But dont forget that chip size is not the most important factor of development, but mostly consumption of w/ghs.

Thats the problem,  too many people are worried about efficiency by the time it takes to make a design 20-30% more efficient other companies are pushing out what they have and pushing the hashrate 5x. Thats why btc mining will meet an inflection point very soon and the arms race will have to slow down with the pot of gold harder to get.  Wouldnt make sense to spend 10 million to mine 1 million. Buy the coins is better.

You are so wrong. The new KnCMiner Neptunes use a 20nm chip.
http://www.coindesk.com/kncminer-finalizes-design-worlds-first-20nm-bitcoin-asic-miner/

Never done.

There is a whole thread about that.

Do your research.

knc is a joke. They are the new bfl.   Just finalizing the design after taking 25 million in pre order money last year. If neptunes come end of june buyers are fcked with the difficulty

Nobody saw working neptune yet, so it does not exists. I'm no longer believing in preorder markets.

The only ASICS that aren't preorder are Bitmain, Gridseed and Cointerra. That's it.

Coin terra , fuck no !

There are many also A1 clones out there ready to go!

Bitmain and Gridseed all the way.
These companies have their sh*t togheter, doing what they promise.

Btw, I heard of this new company: Spondoolies. (What a ridiculous name)
They still have to prove themselves but they should be delivering their hardware next month.

1 nm won't be possible using silicon. That is about 2 atoms wide.

I've been shipped ! I receive 3 SP10. They said mid-april starts the delivery, i received the DHL tracking the 17 or 18th of april.
I trust this company. :)

Be sure to update us when it arrives, I am quite surprised actually.

Large firms can get asics cheaper, especially asic manufacturers - so they outcompete da rest with the help of asic buyers :)

Best choice you would ever do.

I believe that Spondoolies will produce the first 50 terrahash miner.

And even if you could, elektrons would have a significant probability to quantum tunnel through the silicon, which you don't want ofcourse.
I saw an interesting video on this lately, for the people who like to see it: https://www.youtube.com/watch?v=rtI5wRyHpTg (https://www.youtube.com/watch?v=rtI5wRyHpTg)

2 UNITS OF SP10 DAWSON – MAY BATCH
$7,995.00 .... and only 1.4 TH/s of mining power  :P :P :P :P :P :P :P :P
No ROI for sure!

Its two units of 1.4Th each = 2.8 TH

The first (effectively) 50TH miner will be built by a group of mathematicians at Cambridge University and will exploit a new SHA-256 attack. It'll run on a network of standard workstations and servers and the code will be written in scala, using akka remote actors.

ETA sometime in 2015. A big prize is waiting.

Not when difficulty is 200 billion.

huh ?

I'm not sure about that but what will happen when the difficulty just rises too high and miners will be useless? Should they just be thrown away?

They will be melted in the fires of mordor, where there will be made bycicles out of the metal.

Can be used as space heaters

I still have my Jalapeno's as a memoir.  It will go in my personal museum of the house I buy with bitcoins someday. ;)
