If you have it all over like this make sure you treat it like a hot wallet for daily spending.  To have on android is just a not great idea if you have big holdings.

If you do have bigger holdings and need android look at a hardware wallet that works with myccellium.  It is much safer then having private key on phone.

You won't find one in that range.  These still are not bad machines.   They had premium for the quiet vs buying bitmain at the time.  And they have a huge ability to change speed.

.65 I think is pretty fair if anyone is wanting one of these.  Someday when I sell mine I likely will try to sell my set of 3 at once.   But I will mine with them for winter most likely.

Even if they give a indication unless it's a big feature or big flaw I just keep going.  Ever since I bricked a S3 I have not done the do every update method.  I lam on the cautious side.

So if your miner is doing good... there is no reason to update.  And if there was a big reason I'm sure we would read about it in forum.

It's getting colder and colder here.  They are still working in 20F or below here.   So it's good to see cold does not seem to have an effect.

I have also turned off some fan's.  Winter mining is a heck of a lot easier then summer mining when mining a decent scale.

On asic's if there is money they will build it scrypt proved it. Right now SFards is mining LTC internally with the newest gen LTC machine.... no selling to regular customers except a very few.   But it was profitable enough they dumped some money to develop a next gen.  If any other algo ever had a coin that had huge profit's they would look into it... and chances are eventually make a asic assuming it is worth the R/D and dev.

On your fiat crashing... which country are you talking about?  Fiat is not really in competition with BTC.  So I would not tie them directly.   Fiat will always be a part of society for foreseeable future.  There are just some you would never be able to convince to use BTC.

On mining we need to know much more.  Jumping in with 20 miners is not easy... you need electricity that is cheap or decent, and 20 is a LOT of power.  Have you looked if you have a place that can even handle that much?  There is just so much to this part if you plan on mining with 20 miners somewhere you own.

No misunderstanding there is not a S7+.  It would not suprise me if they do have one day... but no sign of it yet.   Right now they have batch 9 that is cheaper so they won't do any change before that goes to sale.   

If they were going to change product it would be after then.  But I'm not sure they might milk current design a few more batches.  They have a design ow with less chips and high freq.  Which should mean more profit for them.   

I have a feeling we can let this thread die. I don't think OP is coming back he signed up asked question and has not been back:

I would guess he did the math and decided not to do it.  But that is speculation.

Look at difficulty jumps though.  I would not want to be .05 with S3 even.  I like a bigger margin then that.  I think I agree with speculation of it being a loss by time  you factor in purchasing price.

I would sell it and go more efficient, or just buy more efficient.    But S3 is slowly moving to very low/free users.  It's kinda the nature of the game.

Gambling is all based on luck.  Games have point spreads to make it where it's more where it's still hard to predict.

A lot seem to like dice it is all luck.   The only one that knows they win long term is the house (were you bet).  I highly suggest staying away from gambling if your goal is to collect btc.  You have to look at long term, not just hoping for a short term win.

The one's that do great at it I think are the ones who sell.  It is risky like any other trading, but the ability to sell your cloud mining shares or machine is important.

A few I know on hashnest made a quick profit when they were out of S7's I think it was.  They got a return in a few day's (or something like that).  The most common will be the ones who use for a while and sell.  But that sell point is the tricky part.

Three attempts and it is gone and will appear like a new Ledger.   You can recovery it from seed words if you do it on accident.  I HIGHLY recommend getting ledger starter if you get one, it's a 100 percent offline OS to make it secure on seed words.

Here is a hands on I did with one: https://bitcointalk.org/index.php?topic=1305888.0

Power cost is huge with S3 being older you really need very cheap/free electricity.  They just are a few generations behind.  The calculator above is great to see your ROI chances, make sure on electricity to include taxes or fee's.

But also on S3+ it stops you from getting one that was a batch 1 dud.  Some batch ones worked great others ran slow.  It was big enough they did give a portion of sale back.    But if you get one that is plain S3 know what it hashes at so you pay proper.  They are like tanks though and pretty much keep working.

That would be a interesting stat.  But no way to really know besides if someone tell us.  I was excited on the R1 it told how many hit, thought that was a cool feature.  But it remains at 0 last i saw and there was still 100 something.  Guess it was limited edition almost.

I really wonder if they are working on u4 or said not worth the time compared to selling a big miner.  Just seems like they would be much more interested in selling higher price which ultimately means higher profits.

That is not bad on estimated.  I wish bitwisdom would show that low:

Bitcoin Difficulty:    103,880,340,815
Estimated Next Difficulty:    112,941,445,366 (+8.72%)
Adjust time:    After 1311 Blocks, About 8.8 days
Hashrate(?):    808,405,177 GH/s

It is estimating high..... but it seems we end up high the last few weeks.

It is a bad idea more hash... is not what you base purchases on unless free electricity.  Virosa post is 100 percent correct. OP would be better off with 2 S7's.  For around the price you mentioned he will have more hash and efficiency around the .30w range.  

So less then 1/2 the efficiency.  Do you see what I mean?  Just makes a ton more sense on .08 cents.

If your in Europe give it a shot. I like to collect OP was amazing on helping me get one in US.   So now I have all the compac versions (at least public ones I think).

But they are the perfect miner for learning mining.  My only suggestion is get a RaspberryPI and good hub and you will really enjoy it without having to use a full computer.

To be fair I think it makes sense in this area not to sell the cord.   There are multiple different PDU connector types..... so what should they do ship one knowing it does not work with all?

I think this makes sense don't charge me for the cable.  And I can buy on amazon to fit my PDU's needs.   If it was a 110/120 I could see your point but with this going to 220/240 on most I don't think they did anything wrong not including cable.

I would disagree with efficiency "0.66W/GH/s".  If you already bought it long ago yes keep mining it until you sell it.  But with .08 cents electricity if buying I would go current gen.

After it is unprofitable then sell it.  But going into old gear is hard at .08 cent's.  Out of curiosity why would you say it is the best miner for OP?

One of the biggest issue's Europe seems to have is vat ontop of shipping.  Shipping cost is not bad but import taxes in some EU countries is horrible.

Your .08 cent's on electricity is decent about normal not great but not horrid.  I would check to make sure that's with fee's and taxes on electricity on that price double check as it is highly important.

If you stick with the two companies shipping this gen Avalon and Bitmain chances are they are not going to scam you.  Or go with trusted on buying used or use escrow it can be a great tool to stop scamming.

How many miners have you had to base that on?   I strongly don't think you can say X company is the best!

I think each model is a different beast.  Some are better then others.  But you cant say X company is always best.
