Show Me The Bitcoin! - use plain images as Bitcoin keys, send BTC via email

Well, feel free to use it then . You can post the clues on this thread if you want. If you have a blog or a website you'd like people to visit looking for clues, you can do that too.

I'm just worried that this app can be exploited. How are you keeping it safe?

What do you mean? You can monitor the app's traffic, it only makes calls to blockchain.info to fetch the balance of a particular address and to push a sweep transaction once you redeem funds. It has no background processes (you can also check this or simply uninstall it when you're done if it makes you feel more comfortable - you can always reinstall it and reopen the image to get the funds). It has no persistent data (well, I'm actually lying, it remembers if you've donated so that it doesn't ask you again - if you uninstall it, it will forget, so it will nag you again for a donation when you reinstall).

Your image isn't posted anywhere if that's what you're worried about. As I said, feel free to use it, then uninstall it altogether until next time if that makes you feel more comfortable.

Nice idea but I would not keep any large amout of bitcoin like this

BTC still hidden in an image somewhere. This one is easy too

Well, I tried but couldn't find it . I should probably add a feature to tell you if funds ever _were_ attached to that image (but have been swiped by someone else before you found the correct image). I've tried all the CryptoCurrency-related pages I could think of but no image had any coins attached to it.

Not swiped yet!

How much BTC is at stake ?

Not much. More for fun than profit

really cool man.

i was able to select blockchain.info wallet or mycelium wallet to send or receive funds. so thats great. super simple design, i really like that.

but i can't donate from an address in the app

Could you not develop an iphone app for this?

[KaChingCoinDev]

This one is soooo easy, but it has been over a day

but i can't donate from an address in the app

What do you mean? I have only tried the Mycelium and standard Bitcoin wallets. Does the donation address not appear when use the blockchain.info applet? Or were you trying to donate directly from some coins hidden in an image? You'd have to sweep those first, then donate.

I think Apple doesn't allow Bitcoin wallets in their iTunes Store. I have an iPhone dev I can ask for help, let's see if he thinks this is doable. Without an on-phone wallet you would have to fund and sweep from your computer or another phone though, SMTB is not a full wallet.

This is probably not a scam. Nice idea too.

ya i was just trying to ship you the coins that i sent to the image while playing around. intuitively, it seems like you would want users to be able to do that.

looking forward to a password or a 4 digit pin that can seed the hash. you can send the image to a friend and provide the pin via txt or voice or whatever. it can also make it fun for having these types of image hunt games. if you add a pin/password, the images could be reused without much worry right?

What a great idea.  Thanks for making this and sharing it.  I think once you open up the source here this will really catch on.  What would folks recommend as the use case for when the recipient opens an email with a loaded imaged attached on OSX/Windows?  By that I mean, what sort of easy to use program could be used to quickly grab the key from the image? (context-menu easy, ideally)

Once source gets up here someone needs to turn this into ability to run on windows

My plan was/is to create a Chrome extension for it - to allow you to right click on an image and check its balance (or maybe hover over it to do the same). This would work if you used webmail or your mail client used an embedded web browser to display the content of the email.
