If it's a 1.5T from lketc you will know it it was roughly 50 pounds to pick up... they but a ton of material in heatsink.   I think whoever you got it from though would have marked 1.5T if it really is to get extra money.

But yes you can run with any number of blades 1,2,3,4 (more on some).  But it makes no difference on odd or even number.  You can do 3 blades only.

Miners should be immune to this. All of the ones I have had do not have a Mic.  So that makes it impossible to receive that sound. 

I you used a windows machine to power a miner or a RPI with mic plugged in... maybe they don't release much details so hard to say.  But I doubt they do a miner variant to say switch pools, etc. 

What are you meaning by tax free?   As far as taxes any wallet should not be charging taxes.

It would be a government doing that info likely from exchange or such.  But there is not link between a BTC address and taxes, you really need a exchange and to sell and have a profit to worry if it's enough to be taxable.

If that is your plan I would do it sooner then later.   You want as much pre-having  mining as you can get.   If you wait close to having it's hard to say what it will look like then, just to far away to speculate.

But I still think buying mine with them, and at having if you have to sell do it.... this for a lot will make ROI (I believe).  And the selling at end could be a important part on getting ROI as we approach having.

Mine will have a little down time.  I have had a RPI2 sitting in it's box and was using a RPI model B.   I figure why not give it the upgrade.  So going to install it all over and should end up with a even better compac setup.  The old RPI model B has done a good job though. 

It has kept it up for long periods of time without any issue.  I need to see if I also can get a modded HUB.   I'm not sure I will be much of a contender on OC unless I do.  I did add a fan and fan controller for fun incase I do compete in OC comp.   The fan controller was overkill but kinda fun controlling the airflow of my solo miner area.

Actually Avalon is a lot nicer then bitmain on their warranty.  Bitmain a sale through 3rd party kills warranty.

Here is from blockc -

4. Warranty Registration and Transferability:

A. If still within the Warranty Period, Avalon Manufacturer’s Warranty will transfer to the buyer, upon equipment resale provided that the buyer contacts Avalon or BlockC.co to register as the new equipment owner.
B. In order to receive Manufacturer’s Warranty coverage, you must notify Reseller with your contact information, the equipment you are operating, and a description of your operating environment.

So just make sure to contact when buying a machine is how I read it.  I imagine you would need order number (proves it's still in warranty) and other info from original buyer, but most I think would be ok giving it i they are selling you a unit.

You are asking for someone to plan your entire operation?  I highly suggest a lot more research before spending anywhere near this amount.   You need to have a good grasp a lot of things.

One huge thing is if you have a place with cheap electricity? Do you plan paying a hosting center?  What is building like, where is it at some cooling systems such as evaporation only work in certain areas.   The list kinda goes on.   My best advice is to do some serious research and come back with more specific questions.

I agree it was one sided on it's writing.  But I think the reason is the 399 price tag most likely.  For that a lot were expecting something different.

I think for what you paid the software would have to be almost revolutionary like they made it sound.  So far all the things coming out sound like it was pretty weak as and they used a RPI ... they did not put into a device like they talk about so much.   It sounds like you can reproduce most of it here - https://np.reddit.com/r/Bitcoin/comments/3tcvb9/balaji_srinivasan_how_21_mining_works/cx59gaj?context=1 .  I have not tried it but if I can reproduce all of that on equipment I have laying in my project stash... it's not that impressive. 

To be honest I not in support of DRM or closed sourced as far as bitcoin software.   But I think being able to reproduce so much for so much cheaper will keep sales low which the price tag already did.

Please re-read it again I am saying the opposite.  Difficulty increasing is going to push it down.  The site you mention specifically investing in has bashed me before as I don't like the graph they post sometimes showing ROI over 100 percent like it guarantees future.  I think we are thinking the same thing.

I just listed some better tools for calculating that are not linked to any sales.  So they have no reason to mislead.

In advanced I believe you can get the private keys on blockchain.  So there are way's of sending even if online wallet is down.  But keep in mind even if you do paper wallet from it it's a hot wallet.  So it's not as good as security.  But make sure you use 2fa on it that helps some.

Cold storage is what you want for storing any sizable amount.  Paper wallet if done right really is one of best ones out there.  Assuming you have it stored safely.

At current level it won't be a huge profit for him.  It's really at full member he will see a good bump in pay for signature campaigns.  I suggest use the first few ranks to learn and make sure to be constructive on posts.  It later on will lead to you getting into better signature campaigns.

Also your posts will not be judged as hard as your learning by waiting.  If you add signature if your posts are very short, one liners, or other things it can lead to a temp ban. So just know that before you jump over. Look at meta they are doing a pretty good job of showing examples in a few threads of some that post just for higher post count.

Same here something like this and the price going up on BTC would have made a decent difference.   I cannot be to sad as I ROI'ed and ultimatly that is the goal of every miner.

But if I would have done this and not sold when BTC was around 230 I could have squeezed a little bit more out of it.  And we always want a little more .

I would not forget about Avalon as they had past miners and have the 6 shipping now.  So they are current aswell.  SP .... they are not really looking for home/hobby buyers currently.

As far as "popular" it's in no way the newest or best efficiency but there are a heck of a lot of A1 chip miners out there.  They come in all forms, shapes, and speeds. So I'm guessing A1 miners rank up there as so many companies were using them at one point.

It can very greatly depending on quality.  Traditionally highest quality airsoft that use gas use like the green gas and stuff, C02 normally follows those.  And if you get into the very high quality they make some very high quality full rifles that are electric.  Me and my friends played paintball and airsoft what seems long ago.  Don't expect paintball like the blood if turned up super high velocity.  But the rifle I paid a few hundred dollars at the time (cant remember was 400-600 range been a long time) it was electric and would leave welts... so they get up there.

I would think this is medium as far as quality with CO2 and no blow-back.  Biggest thing I see is mailing it with the black tip.  Most high end ones come with 2 tips (or they did when I was into it).  They would ship with orange tip on and have black you could put on after receiving it if you wanted.  That is biggest problem I see is no orange tip for transport. 

This is a good replica it just with black tip looks a lot like a Beretta 92 with the accessory rail ( http://www.beretta.com/en-us/92-a1/ ). So with black tip most people who know about guns if not close are going to assume it's real and a gun like linked to.... which could lead to problems.   But I guess that might be what some are wanting.  I would just be careful as it is a pretty good clone as far as pictures shown.

But who are you going to have negotiations with?   A union goes up against a company or such and with a big percent of workforce try to get a certain goal. 

With BTC there is no big boss setting the price of coins.  It is set by a open market.   Unless you control the vast majority of bitcoin mining... which would defeat bitcoin.. it would be impossible to do.  A union just does not fit.

I can confirm if you get from CrazyGuy in thread https://bitcointalk.org/index.php?topic=1197152.0 it works "like a charm" for me.  But he put in a decent amount of time making a custom firmware that his customers can select when buying.   It's this custom firmware that add's the magic, as of now the R1 from bitmain without the custom firmware is not a fix.

But I got lucky and ordered from crazyguy (was trying to save shipping vs buying unit and adapter day one, but adapter turned out not needed for US plugs).  It has saved my time I was wasting with 3 U3's resetting so much.

Also consider the 100 price was with BTC around 230.   With it going up to around 330's it is bound to go up with it.  Just the way the system works.  Miners are worth more when BTC has a higher value. 

So at this point it is much harder to get 100 dollar S3, but at 230 you could easily find it some with shipping even. 

It's not only bitmain.  There are a few options.  Really two main miners shipping the Bitmain S7, and Avalon 6. There are many  miners from previous generations.  There are some smaller lotto miners... but I consider them in a different category myself.

SP gear really unless they change will not be for individual use it's going to take a huge investment.   And no sign they have a working prototype yet.  Also waiting on the B-11 miner but again no sign of working prototype.

I think the price kills it from  being anything usefull as far as device.  I think they did it to prove they have chips and as prototype.  As far as chips compare this to traditional big miner.... a LOT less chips are used and they get to say they have a product now.  But it's going to be a massive profit for them on any sell.

I have not read anything yet to get me to spend the 400 on it.  I think they could have done better.  I mean to be the company that talks about having mining chips in other things... then comes out with a RPI with top is not all that impressive to me.

It stayed at 230 a pretty long time on floor.  I don't think you can completely give credit to only having on increase.  It's still a while away in mining terms I still say that far cannot be very  accurately speculated.

But I would love to be wrong and someone have a good speculation.  But i think just to many unknowns.
