Bitcoins security has a much larger field to bury the digital coins in. Consider the available space on earth where you can practically store/hide your PMs. How many cubic feet could thefe be available to you? Now consider the space available to hide your bitcoins... There are more private keys in bitcoin than there are atoms in the known universe. Think about that and let it sink in. And then consider that it is, while some what above the average users technical ability today, entirely possible to hide and spend your bitcoin in one of those large numbers from a completely offline computer where your secret is completely safe from hacking and malware.

Money is simply a ledger. The security of the ledger depends on the properties of good money it has: scarcity, fungibility, portability, consensus/acceptance, durability. History has proven gold/silver to be the overall best of all these properties. But now bitcoin will challenge the current champions and create new financial products and services the world could never have witnessed without it.

Feature request: regarding bips38 cold storage spends... the passphrase is echoed to the screen and not obfuscated with asterisks - and left that way during decryption. This should be hidden from the screen asap once entered.

A checkbox to show password also makes sense. Also have the screenshots prevention active there.

Feature request: I'm using mycelium as a POS for a local merchant. It would be awesome to have the ability to brand the background with the merchant's logo. Also, it would be neat to be able to dim transactions in the transaction list to "mark them as acknowledged" so they won't be confused with the next payment. It could be something like a simple toggle and not even persistent necessarily. Perhaps a way to persistently tag a transaction with an order number though would be useful.

Thanks for the suggestions. We have, and still are, debating internally how we should make Mycelium better for POS scenarios. It is hard to make one tool that is perfect for all use cases, and one solution is to have separate versions. The POS version should be a lot simpler, and preferably not require prior Bitcoin knowledge by the operator.

You've misunderstood many things about bitcoin, specifically, there isn't 21 million bitcoins that can be created.. There is 2.1 QUADRILLION bitcoin "pennies" that can be created. Each bitcoin is divisible to 8 decimal places. @ $1000/XBT, you are actually buying 100,000 monetary units of Bitcoin. Keep researching.

Sorry to see fellow stackers missing the bitcoin train. All I can say is educate yourselves. Let your ignorance go and learn how to take advantage of bitcoins innovation. Hope you figure it out sooner than later. Good luck. Stack gold/silver/bitcoin : all are good money.

monetary units are limited to 21mm by a rule in the protocol that divides the block reward in half every 210,000 blocks that get created. a feedback loop built i to the protocol throttles block creation to once every ten minutes. the initial block reward was 50 bitcoins. this is sufficient information to calculate the maximum number of bitcoins that can be created. 50 bitcoins every 10 minutes for 210,000 blocks means about 10mm bitcoins in the first ~4years of operation. then the reward value calculates to 25 bitcoins every 10 minutes for the next 210,000 blocks. and so on, until the block reward equals less than one satoshi (smallest bitcoin unit) and no more bitcoins are created. inflation will happen for about 130 years. sometime before that, the incentive for processing transactions on the network will shift from inflation to voluntary transaction fees. read "satoshi white paper", 9 pages, for a more detailed explanation. i like your passion, keep it up!

I'd like to report a bug with decrypting cold storage keys... if you fail the first time, and attempt to fix the error and use the decrypt button again, it says "preparing decryption key" with no progress and the decrypt button goes back to a "pressable blue". It looks like its doing something, but it just sits there for ever. If I press the decrypt button again, the button goes gray and does nothing.

I encountered the same issue few days ago, after putting the app in the background and then back to the foreground (home button + reselect the app from recent apps) it showed the progress %

Question about Cold Storage. In the past, after scanning in the encrypted private key and decrypting, there were options to specify a send address and amount. Now, there's just a "send" button. I have no way of telling where the bitcoins will be sent or how many without hitting the big scary "send" button. I am not brave enough to see if the app will ask me where and how much to send AFTER I hit the only button available to me, called "Send". Am I missing something?

When you have done it once, it does become familiar like the Send button.  This is a more natural approach because we know to a certain extent how the App functions.
Though it is predictable that when we pull out funds from CS, they are being Sent somewhere, then the SEND button is understandable.  The SEND button on the main page is more like descriptive, whereas, at the end of a transaction it's more like the 'execution of'.  I can understand where one can be confused.
May I propose, if the Send button is not linked to other Send buttons in the App, it could be followed by 3 dots EX: SEND..., or just have a different background color.  When a buttons leads to another page in the App, it can have the blue background(BG), and when it terminates a process another BG color.
We know people get uneasy when terms can be misleading, specially when playing with a form of value, in this case BTC.  Personally, I think SEND is the right button to go there.

Hey guys, I ran into a potentially devastating situation yesterday during a trade and thought you might like to try and address it. I started to spend to a person I was trading with, for non-trivial amount, and put in the number of bitcoins I needed to spend to him. Then I scanned his bitcoin address and hit send. The problem was that his QR code had an amount embedded into the QR and silently updated the amount I typed in. Fortunately, the amount he specified was lower than what he was owed, and he was a trusted trader, and the key I was using was only funded for what I needed to spend to him. But as you can see, this could be devastating if successfully exploited. I recommend a popup or similar if the current amount does not match the encoded amount, OR do not let an amount be entered until the QR code is scanned.

Gold/Silver is backed by the physics of the universe. We have conquered physics enough to make gold using a similar process to nature, but it is still quite expensive. Bitcoin is backed by mathematical rules that govern how the monetary system is inflated and operates. The strength for bitcoin is that no matter how much energy you apply to a system, no matter how you bend the time/space continuum, 1+1 will always equal 2. The blockchain, every transaction that has ever occured and will occur is secured by this infalable and uncounterfeitable math - regardless of any future technology or power innovations.

Amazing massage. Was expecting and asked for just my feet, but got some love on my head and shoulders too. Definitely will be back.

OMG I enjoyed myself here. The filet minon was cooked EXACTLY to my request and it was perfect in every way. The spicy thai green beans were very tasy, but the Flemmings potato side was off the hook. Amazing evening.

I was scolded by an older female for crossing some invisible line in the store. When asked where this imaginary line was, she continued to berate me for not identifying the narrow passage between furniture as being different from the other narrow passages that were apparently ok to cross. She even thanked me when I said she just lost a customer for being rude. Never be back.
