I still have an Android device so I'll be able to take a look, but my mobile is a Blackberry 10 (Q10) device.  I'm seeing a lot of Android apps that can be packaged for BB10 without much effort.

Where are coins held while receiving wallet is offline? I'm assuming they stay in the blockchain.

From another thread:

The way it works is confusing because the plumbing underneath is actually different from how it is presented.

Coins don't actually get held in a wallet.   The blockchain is a transaction ledger, and every full node with a blockchain has a copy of it.  The only thing in the wallet on your client essentially is the private keys that allow you to spend the funds for certain addresses.

Because people are familiar with the term wallet, since there is one in most back pockets and purses, that's what the clients try to emulate.   So the Bitcoin clients use the same concept of receiving and sending money as you have with a physical wallet for cash, but that's simply not what happens.

When you send a payment, you are simply broadcasting your permission for value to be transferred from previously received transactions to new bitcoin addresses.

When you receive a payment, that is simply the client showing a filtered view of the blockchain ledger for a specific address.

If you take a look at this thread you will find that about 80% of the miners are mining with only a couple of cards, and not with purpose-built rigs.
https://bitcointalk.org/index.php?topic=162345.0;all

And 20% of the miners are producing 80% of the hashes.

[I'm not saying that's optimal, but there are plenty of significant mining operators each with a lot of hardware.]

Does the summer months have an effect on the difficulty?  If you spend most of your time in the same room as GPU's mining 24/7, it's gotta get pretty uncomfortable.

There was some of that.  But this summer, if the heat doesn't shut them off the rise in difficulty vs. rise in price definitely will.

But then we have the last mile problem. Where can you shop with bitcoins besides a few places that are accepting the currency as a marketing gimmick?

I doubt Cups and Cakes in San Francisco regrets their "marketing gimmick" whatsoever.   If accepting bitcoin payment as a way to increase revenues is a gimmick, it certainly pays off!

Or perhaps the author is referring to BitcoinStore's offer to NewEgg and Amazon ... "accept bitcoin and we'll shut down", ... ok, that's a gimmick.

But the pace of organic merchant adoption is increasing.  My next domain name registration or renewal will be through Namecheap, paid for using bitcoins.  For my next travel, I'm going to try to stay at a place listed on 9Flats, paid for using bitcoins.  And where I can't pay using bitcoins online I can proxy pay I'll try using BitSpend.net (which places the order and pays for me).  

Bitcoin probably isn't ready for bricks and mortar commerce though.  Though a "race attack" against a merchant isn't something all that common, bricks and mortar merchants who accept bitcoin payment don't have much defense against those.  And there isn't a point-of-sale provider specifically to help retail merchants (e.g., with advice or insurance against double spending).

Where is my BTC ATM?

Technically, such a device exists today -- and existed was a prototype way more than a year ago.  Thanks to regulations, that never made it out of the lab.  It looks like one is coming, however.

Will they take Bitcoin at the exchange desk in the airport?

Travelex should.   This could be offered by anyone (e.g., buy bitcoins by sending payment of the foreign currency through the mail) except again, if this is considered being a money transmitter regulations make it so only the entrenched retail foreign currency exchangers are set up to handle this.

We are either at or within a day or two of coming up on the one year anniversary of SatoshiDICE.  I see the forum post for it is April 24th, 2012 but the list of secrets goes back to April 17th, 2012.

1051  Alternate cryptocurrencies / Altcoin Discussion / Re: I will create a forked bitcoin chain on: April 21, 2013, 09:30:39 PM
Seriously dude?  Thats mondo easy.  take all the adjust values for unspent outputs and write them into the genesis block to the address they belong as coinbase txs.

I was interpreting wingding's statement as describing how coins issued prior to the fork would still be spendable on the inflatacoin side of the fork ... that they wouldn't be touched (i.e., "harmed").    But my assertion is that any spending of a "pure" coin issued pre-fork is a valid transaction on both sides thus any spending on the inflatacoin side is harmful to the holder of the coin.

A pure coin is one that has no taint from the coins issues after the fork, and thus would be a valid spend transaction on the Bitcoin blockchain side as well.

Now I suppose you could ensure that the inflatacoin client included in every spend transaction some taint in the INPUTs so that the transactions would only be valid on the inflatacoin side.  I still personally wouldn't use any coins with that client until they've been fully spent on the Bitcoin blockchain side, but after that I might milk the inflatacoin fork for whatever I could get from it, sure.
1052  Bitcoin / Bitcoin Discussion / Re: Question about double spends/transactions listed on blockchain on: April 21, 2013, 07:53:21 AM
I understand the transaction is listed as a double spend

That transaction had inputs that were also used in another transaction, so that's why there is the warning about the double spend attempt.    The transaction you linked has confirmations. It is valid, and is not the double spend.

As far as the double spend transactions that existed at one time ... blockchain.info doesn't retain those indefinitely so there's no telling today what had happened back then.
1053  Economy / Web Wallets / Re: Blockchain.info - Bitcoin Block explorer & Currency Statistics on: April 21, 2013, 07:51:59 AM
I'm wondering why Blockchain.info is having trouble with this transaction:

 - https://blockchain.info/tx/d3887aa543417c6934e7831407d017ec15b4b288a23cdd2977505a6ea1aff739

When I enabled "Advanced" I click on the (Spent), which is the URL:
 - https://blockchain.info/tx-index/66120873

but am given the response:  "Transaction not found"

But here is that transaction:
 - https://blockchain.info/tx/440a659b8298dcc0ac336e1c245472f6bcc48a90d978a746241c74b4368ae92e

So is this just an indexing error somewhere?
1054  Bitcoin / Bitcoin Discussion / Re: Does Bitcoin need a "stock split"? on: April 21, 2013, 07:25:06 AM
What do you think?

Your title doesn't match the body of your post.   A "split" is different from changing the "display format".

The display format most people want to see probably won't be cBTC, but instead mBTC.

Just like the Bitcoin-Qt/bitcoind client allows you to choose whichever display format you wish  (BTC, mBTC, uBTC), I expect each exchange to have a profile setting allowing you to choose which display format.


1055  Bitcoin / Development & Technical Discussion / Re: Probable Dead Bitcoins on: April 21, 2013, 07:04:28 AM
Also cold storage coins would also suffer the same fate. It's not suppose to be a perfect metric. It is giving an effective bound on deflation from money taken out of normal circulation

Nice round numbers likely aren't lost, so you probably want to have two different rules.  For example, a 7.23512343 coin that hasn't moved in years might be a lost coin, whereas a 250 BTC coin that hasn't moved over that same period of time is much more likely to be the address for a private key printed and stored in someone's fireproof safe.   Also, the value at the time it was sent will matter as well.  I would be more likely to understand that someone would have abandoned a wallet with 4.0 BTC in it in late 2011 due to having forgotten the exact encryption passphrase used, whereas today with a 4.0 BTC wallet it would be worth it to try a cracking utility to try and regain access to the wallet.

1057  Economy / Trading Discussion / Re: Keeping track of trades on: April 21, 2013, 02:36:35 AM
Hello. I'm passionate about bitcoins but have no experience with somewhat frequent trading of stocks, currencies, or commodities. Can anyone recommend a good website, or application, or program, that I can use to track all of my bitcoin trades, expenses, profit, etc.  I have been using an excel spreadsheet I made but I'm sure there are better alternatives out there.

There is a personal finance manager that will read from the Bitcoin-Qt/bitcoind client, and others:

1058  Alternate cryptocurrencies / Altcoin Discussion / Re: I will create a forked bitcoin chain on: April 20, 2013, 07:15:10 PM
No I would never ever touch the earlier coins

How would you do that?

From another thread by winding:

looking at this guys older posts... people have been trying to explain to him how bitcoin works... looks like he is just refusing to understand it... and really want to get his early coins... so sad... (me is still sitting here very happy finding out about it in 2013, instead of 2016, or 2020)

And yet another thread by wingding:

The address is valid in both sides of the fork.  So let's say that somehow you trick me into spending my bitcoins that I received prior to the fork and pay using them to an address in your inflatacoin fork.  But then you can then use that exact same address on the Bitcoin blockchain side as well, broadcast my transaction there and receive the full value of the transaction there as well.

Participating on your side would be seen as the way to watch your bitcoins disappear.

Because there is no way to ensure that all transactions from the Bitcoin blockchain get into your inflatacoin fork, then the only time your chain becomes interesting to me is after my transaction confirms on the Bitcoin blockchain but where I've composed and sent a double spend of the UTXO used to your side of the fork, and then pay you with those funds which are now worthless on the Bitcoin blockchain.  That's a win / win for me!

1059  Bitcoin / Press / Re: 2013-04-18 FoxBusiness - Bitcoin Buzz Draws Western Union, MoneyGram on: April 20, 2013, 04:56:21 PM
Western Union is roughly in the same position now as Blockbuster was in 10 years ago.

Exactly.  It isn't that blockbuster couldn't rent a movie at a profit, but that they had to get a lot of customers through the door so that little bit of profit per-movie multiplied many times was sufficient to pay the lease on the retail space, the staff, utilities, etc.

Western Union's model is tied to a two-step process by one company ...    Western Union receives money in one location and pays out that money (less fee and conversion costs) to someone in another location.    Bitcoin obliterates that model as there are now to independent actions that occur.  One party buys bitcoins in one location.   A different party sells bitcoins in some other location.     This means there is no reliance on a trusted party in the middle. 

This eliminates all the hawalders as well.   Well, not eliminates, it simply allows them to work independently.  They simply become bitcoin exchangers.  It is much easier for them to not need to deal with both sides of a money transfer.

Since money transfer is a business with an 8% to 20% vig (depending on where from and where to), there will be a lot of people who will welcome Bitcoin's arrival in this space.

1060  Bitcoin / Development & Technical Discussion / Re: Bitcoin versus Credit Cards, help Bitcoin compete on: April 20, 2013, 04:27:20 PM
Another solution would be to ask customers to "please enter your refund address" in case of a refund. Online wallets can play a role too.

I'm not going to comment on the "automatic" part of the refund process, but as far as the actual refund payment, you are correct that a new address needs to be obtained to process a refund.     This is a problem when the original purchase may have been made without an account and perhaps from an E-Wallet where the buyer doesn't have control of the address used to send payment.

This opens it up to where any party can request a refund on someone else's order in this scenario.  

Most E-commerce involves use of an authenticated account (e.g., authenticated username and password), so this isn't a problem for most merchants.   If selling anonymously, or without account authentication, then either a refund address should be provided by the customer at the time the order is placed (yuck) or the refund handling would need to be something otherwise appropriate.  For example, if a physical address was used for the order but a refund is requested then a letter with a refund verification code could be sent to the same address.  There are workable solutions that protect both the merchant and the customer for nearly every scenario.  

There is a payment protocol being built for the Bitcoin client that will further protect the person sending payment:
 - https://bitcoinfoundation.org/blog/?p=85

Case B: split payments
Use case: the European Union has enacted laws that customers may not be forced to pay >50% of an online purchase in advanced.

There are laws affecting specific payment methods (e.g, credit cards) that don't apply to other payment methods (cash).   If something like a payment sent upon notice from the delivery service were desired,  an escrow partner could facilitate that.
