No you need to have a connection to the network as you transaction needs sent in it.     You mention wifi could be dicey during buying/selling.  If your talking about buying and selling in person you can use a smartphone in some cases where you use cell phone network vs wifi.

As far as security some hardware wallets can connect to phones via OTG cable and allow pretty save storage/sending even on the go.

I could just be lucky then I have had mine since GPU mining day's long ago.  Eventually they mined asics, but that have lasted a long time.   They have went through winters, summers.  Mining in house and mining in a mining area.

I never had a issue with all that so I still think a good gpu.  Although I admit when getting PSU's later on I got the EVGA to get 1300 vs 1000.  And now it's all about the server psus.

What are you saying great job for?  They have a prototype no miner to sell to general public, heck I don't think we even know efficiency of prototype.  So there is not a lot of good things.   

I would avoid company till they prove a lot more.   Also I would want to see possibly  a better design look at their site when it's hooked up near water heater.   That is just something most "home miners" won't be able to do on install I dont think.

Were almost to hit 470, right now were at 469 and change - https://www.coinbase.com/charts  so very good news there.  Still have a day or so in period for it to go up even higher.

Bitwisdom has us at less then 2 percent right now which again.. great. 

Bitcoin Difficulty:    178,678,307,672
Estimated Next Difficulty:    181,474,058,138 (+1.56%)
Adjust time:    After 178 Blocks, About 1.2 days
Hashrate(?):    1,235,895,416 GH/s

So it's looking like this difficulty change will be a good thing for us.

And they very well might not I can see how there is a lot more collectors of stick miners, then bigger machines it seems.  But I guess it depends on his mining setup.  For me if truly 5 dollars each I would pay that just to put in mining area as a decoration of sorts as I have a decent amount of room.

But I can see what you mean if someone is counting on it and holding it to sell as a collectors item in a few years likely they will be disappointed.   But a decoration or even a project/parts for project 5 dollars each seem like a steal unless they really have dropped this low in value and I just did not see it.

ROI is honestly hard to tell you as difficulty changes really can be tough to speculate, this current one looks good.  Also value of BTC hard to predict this period again it's been pretty great.   But not all periods are as good, it's not a guaranteed ROI.  Also new machine no one can say this, that is a questioned speculated on but no anwser supported by fact's that I know of. That being said I still love it and will always mine.

How much free electricity do you have access to?  Does noise/heat matter in the area?  

On blockchain I did do testing with Yubikey's (a 2nd factor device ) - https://bitcointalk.org/index.php?topic=1353231.0

They are a great tool to ad 2fa to blockchain.info as they are supported.  To get the second factor the usb device has to be in computer and you physically press it.  So about as secure as you can get on 2fa.  I like the part that you have to have the physical token, and it's not on a text message or something a "bad guy" might possibly have a way to get/see.

Your system could be the best faucet in the world (I personally don't think it is) but lets say it is you still pay cent's per hour's.   That is just how it works out nothing against you but faucets earn dust.    Your offer of 1000 satoshi sounds great till you do math and see it is " USD $0.0046549000".

And you can make argument PC would be on anyways... that is valid I have some on 24x7.  But your still wasting time you will never get back.  I would try to get someone to use time to learn a skill.  If they did this instead of hours of faucets they will gain so much more long term.

For your "Unique" system to be considered something special I think you need to pay off all investors.  If you are able to pay off all investors and then prove you pay better then cents per hours you will get a lot more people who listen.  And I still think paying off your paid investors needs to be done before you can claim sucess.

Not sure what your questions is or what we can help with.  Paypal is it's own beast, it has many rules and they can get complex as a seller.  If you have large/unusual amounts it would not surprise me that they want your account verified as you mention above.  I can understand as this is to prevent fraud/scams.

You will not find a ton of love for paypal on this site.  It is not ready for bitcoin sales due to chargebacks you can really lose selling digital goods.   Also selling miners they still can refund sometimes for questionable reasons.

So you will find others that have ran into problems.  But as far as helping not much we can do with paypal help.

You laugh but it has happened on some miners.  Look at block erupters people collect them and some even try to get every color.   So they go for way more then they are worth.

So we have seen some collecting of miners.   If I ran across 3 S1's for 15 dollars total... I would probley go for it and worst I set them on shelf.  For 15 dollars... I don't think you can go wrong.

I'm not sure I thought water cooling would be fun once... got two C1's.  I have to say I like air much more.  All depends on your setup but with having my mining area I would pick air all day long.

If something goes wrong... that is a lot of fluid and near electricity.  I was scared when I saw one of my syscooling pumps fail and water came out of it... it got lucky with positioning it dripped down a old table and not twords electricity.

They have not made any big announcements that i know of... so I'm thinking we will never see mass production.

Since new page I will post last anwser from Marco:


So I think not yet once new campaign launches I would guess it will be pretty easy to tell, but it has not yet.

We still have not hit mass adoption.  Were so early on in crypto currency it's hard to say what it will look like in 5 years let alone more.  So people are still early, look at rise this month. 

So you can earn money and some do it as simple as just holding coins for a period of time.

My advice is spend some time learning how to use the forum.  There are at least 5-10 on this topic on front page of newbie part.  Some have ran for months and have more then we could ever tell you quickly in here.

So I hihgly suggest goinging into Beginers & Help forum read the topics and I promise you will get much better luck.  Also if certain part you want to know about within it search it and chances are someone asked it as far as "earn bitcoin" topics.

Only time I use self moderation is in my reviews.  As everytime some try to use it as a hardware sales (it's mean for support), or they just like to spam it.    I personally don't care newbie or legendary as long as they bring good information/posts.  So I don't see a huge reason for trying to be just legendary.

It would create like a "club" that really would do nothing.   I cant think of any topic I have I just want to limit to legendary accounts.  Normally I enjoy talking to all levels, and all parts of the world.  And I enjoy helping and talking to new people... so that could be why I don't see reason to have legendary board.

so my Question is can i make Profit from two "AntMiner S7's" on todays date? if yes,
We really need to know more as profit means making above cost of running.  What is your electricity price?

HOW MUCH BTC CAN I EARN IN A MONTH? and can start earning from first month?
Again really need electricity price to be of any help.

- how much internet speed did i need to make it run properly?
They don't take much internet speed but you do want something with not huge latency.  If your ping is horrible possibly could effect mining.  But any modern dsl, cable, etc type of internet connection will work fine with 2 (and could handle a lot more)

- if i want to stop mining i near future, will i able to sell it in indian market?
You will have to check around on local markets.   I cannot say much on Indian resells as they are not that common in hardware sales... so we lack data.  You would have to find this out on your own or look for local sub board to ask in.

I think it would all depend on resale with 11.6 cents.  He would have to mine and sell at a profit so partially at mercy of bitmain and hoping they don't drop S7 anymore or he loses then.

But that is only choice I see is buy and flip which can be dangerous on ebay.   He could wait till next gen whenever it hit's and likely get a decent amount of time mining with it before having to sell.

We are a LONG way's from 2,000 though.  Were celebrating a 60 dollar or so raise from the 400 day's.  But to get to 2,000 is not going to be a near term goal even with having.   

If we hit 1,000 anytime soon I would be very happy to see.  I do think 1,000 will be hard to hold with sale walls and some cashing out some if it happens.  And honestly we have been really just picking up last 2 weeks or so, we might stall anytime and not keep this gain going at least as quick as it is.

And I see payments went out it looks like to, so you might check again.  I was thinking it said the 26th on next payout (Could be wrong been a crazy start to week).  But I think it was on time or possibly before date mentioned.  So thanks again Marco!

It should only be used as a hot wallet (so keep only daily spend in it).  Also make sure to use 2FA, lazyness without it could cost you the BTC stored there. It's a great wallet just should not be a main wallet for your holdings.
