You really have two options.  Move to a different algorithm.  Do ROI as GPU is hard to profit for most people now.

Other option sell cards and get a Scrypt miner.  It will use much less electricity on mining Scrypt and have much higher hash rate.

Only thing you might think of is using multiple wallet's (which would be different addresses).  This way not all your bitcoins are in one wallet for security.

If you google you will see videos of the button's and how to do it.  If it dose not work, let the battery die and try again.  But most likely the button's will put it in restore mode.

Yes it's on hardware forum.  If you search there is a Dragon guide.  The is one by pcfli with instructions I know because I uploaded a image to it .   

If you search you will find it and instructions, make sure to use 2nd sd card 8 GB or bigger with it.  Don't use original as if this dosent work we want to still have that card.

Currently 2 dragon 1T's available for rent at time of posting.  Accept paypal and btc payment for rental's.

A2 should coming back soon.  Currently one rented and other is doing quality testing to check up-time and speed for next rental.

Happy Mining!

We will have to see what happens on difficulty the last 3 have been 5%, 8%, 3%.   I can't predict jumps in difficulty but i think we are looking at <10 at current equipment out there.  Difficulty is trending in a good way for us miners lately in bitcoin mining, this is personal opinion.  I know some experts who estimate huge network increase, and others who don't only time will show.  But as of last 3 changes we have not hit 10 and look promosing.

Also the S3 will have a value for foreseeable future.  You will see S1's have customers still for undervolting for example.  I think at the end you can count on someone wanting to buy.  No one can predict that price though on that.

Can you post your settings for networking?  And router gateway?

Just first guess try 8.8.8.8 see if DNS is set wrong in S3.  If that does not work the rest of information will help with trying to figure it out.

Looking at pictures of Ebay auction at least one is a standard 4 blade dragon.  It looks like there are different models of A1's on auction.  (different vendors)
 
You could try to flash a second SD card with a firmware for a dragon with known IP and see if that works.  Again I say flash a second SD card since you should keep the original.

A processor stands no chance against in scrypt.  It makes no sense to mine on a tablet especially mine LTC.

So much depends on each person's situation.  This is broad and inaccurate. With someone like me with lot's of space and decent power price minning is very much alive on Asics.

Yes GPU/CPU days are gone.  But ASICs are still possible to ROI in my situation.

You could use localbitcoin or mine coins.  But keep in mind if there is a "good" as you put it who ever you are buying from is sending it somewhere assuming it's not digital.

What type of "good" are you so worried about?

Yes bitcoin's with blockchain can see were sent.  Depending on way of getting it depends on if they can tell how you got the bitcoin's.  This question is hard to read are you worried about being anonymous to seller of "goods" as you put it?  Or are you worried about getting from trusted source?

Honestly reading the boards will do you more then a book for mining.  A book that explains bitcoin might be good if you completely new.

Mining changes so often a book would be hard to keep up to date, it would really need to be electronic and constantly updated.   Look into if hosted or at home mining is best for you then pick a machine.

It will have more to do with your budget, and risk level.  All very personal things not something a book can tell you.

You will need to go into more detail's with being new.  Most likely will need to have a escrow with payment for people.

Very true.  There is a lot of hosting option you basically point to pool and done.  With in home you pick miner and plug it in then point to pool. (this assumes you have a bitcoin wallet for the bitcoins to go to).

There is not real trick just doing right calculations on ROI. Lower the cost the higher the profit(this assumes you operate in profit).

Depends on frequency of your S3's.  At standard freq.  That wattage SHOULD be able to as long as 4 separate PCI-e connector's(one cord with 2 adapters on it counts as 1  PCI-e cord).  I have two running around 680 on killawatt right now.  That being said there is a possibility they could peek higher depending.   

It depends a lot on electricity prices.  For me CPU/GPU is dead but asic very much alive.  I am lucky to have lot's of space and decent priced electricity.

Begining of summer i pulled 8500+ watts of GPU from mining as summer heat removal and mining profits just did not make it worth it, was better off selling GPU's and getting asics and electricity and cooling cost have been much less.  Making it profitable for me on asic's.

It really is a very individual thing on ROI.  And there is hosted mining for those who have high electricity or no space.  Again machine price and monthly price with bitcoin going rate depend make/break your profit.

With Scrypt its harder to predict then bitcoin.  Difficulty/coin price is a lot harder to predict then flat BTC.

It does cost more they claim it adds even more security to your account.  You would have to sign up for it so you would know about the extra fees.

You are asking for trouble GPU mining with laptop.  Do some ROI and it most likely will be a loss, if you get anything it will be small with 1 card.

I highly suggest if your wanting to mine getting a proper miner.  Also you can just buy bitcoins if you don't want to mine.  A laptop can mine..... but many like me will tell you it's asking for trouble doing it.

It's mainly the ROI factor to me.  It's much more efficient for other "machines".  Most ones with newer chips are high price per GHz.   And older ones are cheap like BE's, but speed is slow and add in hub cost.  It's most likely far better to get a bigger miner.
