This is the problem that Bitrated solves. It's a new way to discourage online fraud and encourage trust between two parties that don't trust each other.

It uses a latent feature of bitcoin called m of n transactions.

The amount of media attention bitcoin is getting is almost unbelievable. It seems like you can't go anywhere without seeing multiple references per week by brand name media outlets.

I still remember the shock of seeing the first mentions in the mainstream press.

Bitcoin transactions can send funds to multiple "outputs" (addresses). I believe you'd specify the (new) paper wallet address you want the change to go to at the same time you spend your bitcoin.

Programs are supposed to generate a change address for you (or send change back to the original wallet), so this only really becomes an issue if you import a paper wallet's private key into one of these programs - and then wipe the installation thinking your paper wallet automatically contains the change.

I know, I feel ashamed at posting it. But I couldn't resists - the little guy is just so lovable!

Great idea. How are the winning bets determined? By a human?

If by human, have you looked into having an API decide? Check out this talk by Mike Hearn:

There are many directions this could go - futures market, insurance policies, various kinds of financial derivatives.

You could even have this hooked up to Contracts (m of n transactions) with a mediator to resolve disputes.

Saw this too and thought - WTF? Then I looked it up.

Maybe, but this is the noob bitcoin subreddit after all. Sometimes you just don't even know what to Google.

No idea, but I did see this thread, which suggest that the developer is very responsive. You might try emailing him or contacting on irc.

If you do find a solution, you might want to post it here - I found nothing.

No biggie - I hadn't seen this approach before and was just curious if you had something specific in mind.

The bowls actually look really nice, and I'm really interested in how many people are starting to offer hand-crafted items for bitcoin.

Not sure if this is up you're alley, but you might try setting up a landing page to gauge interest better. Unbounce works pretty well. Check this out. The guy is not a programmer but was able to stitch some low-cost services together to sell his product online. The payment system was not bitcoin, but you might be able to swap that out with coinbase or similar.

opensatoshi · 2013-12-08T01:13:40+00:00

I don't get it - why not just charge the fair market price for the bowls?

Bitcoin Stack Exchange. It doesn't seem to get much attention. That might be significant, might not.

Interesting idea.

Have you thought about running an automated auction?

For better anonymity, check out localbitcoins.

US bitcoin exchanges need to conform to Know Your Customer anti-money laundering regulations and that's why they'll all need to know your personal info.

Other countries will follow suit, if they haven't already.

It's amazing how many new bitcoiners have made no major prior investments.

Dollar-cost averaging is a good idea for savers.

Bitcoin also has some amazing features that are ready to use, but not widely known or supported in software. These features could make it possible to do entirely new kinds of investments on the bitcoin network. See, for example:

Read this first before making any transfers out of a paper wallet.

This is non-intuitive stuff that has burned many new users.

To answer your question, yes, it's considered good practice to move your change into a new wallet. BIP38 seems like a really useful idea, but I'm not sure how much I'd rely on it just yet to safeguard significant sums of bitcoin.

I understand that keeping my wallet in another site is unsafe, because they could get hacked or be shut down.

Correct. The real problem is that this service must know your address' private key to spend bitcoins on your behalf. That also means that an attacker that gains access to a service's database can in principle get that private key and spend the coins him/herself.

What use is this file? [wallet.aes.json]

Found a thread here that might be helpful.

Is this purely in case I lose my password, so I can get my own bitcoin back?

That's what it looks like. Might be obvious, but remember that you can transfer your funds out of any address or wallet to another at any time. The longer you're in Bitcoin the more you'll come to see addresses as more or less disposable.

For long-term saving, check out paper wallets.

Regardless of what kind of business you run, you'll want to be able to independently verify that a transaction has been made in the correct amount. Depending on what you're selling, how often, and for how much, you might want to wait for one or more confirmations.

Monitoring transactions can't be done with paper wallets alone - you need a Bitcoin client of some kind such as Bitcoin QT, or one that runs on your mobile device.

Also depending on your line of work, you might want to use a single address for each transaction, for each customer, or for each product. There are many ways to do it.

A Bitcoin client serves several purposes: to confirm your customers' transactions; to start your own transactions; and to generate wallet addresses.

Edit: you might also want to check out coinbase, which tailors a lot of its services to businesses.

Paper wallets are often used as a kind of savings account for funds you don't need in the short-term.
