Beautiful :) I didn't know people were moving around such large sums. I saw a 3400 bc bubble, and a 2000+ bc bubble floating out there.
I wish I was able to distinguish what was going on directly from the sounds. Those huge bubbles sounded exactly like the small ones, and when I saw 50 bubbles appear at once, that also did not sound any different than a single bubble. The amount of simultaneous sounds seems to be limited to a very low number.
Bitcoin clients usually try to diffuse coin ownership by always sending two amounts with one transaction, one (normally smaller) amount is to the receiver, the second amount is to a new address of the sender. So your coins diffuse out over tons of addresses this way, and the true number of coins transferred between individuals is much less than it appears.
It can also be extremely unhelpful, for example to this chap today on reddit:
Who didn't seem to know about return transactions and seems to have lost 90 BTC on that. (Because he/she used a "secure" live environment that would work with a temporary wallet and just one extra address with his/her money.)
This. If you save all wallet.dat files on any bitcoin clients that you use for transactions, you'll be fine. Don't be scared off by someone using the bitcoin client in a non-standard, unapproved way (and as long as you use the GUI and not the command line interface, you'll not have to worry about that).
Just make sure you understand the software you are using. This mechanism isn't good for the user since you negate the efficiency of backups if your coins constantly move from older addresses to freshly created (unprotected until next backup) addresses.
Some bitcoin clients fix this by using a deterministic generation of new addresses for the wallet.
Change from outgoing MtGox payments does show up in the blockchain, though, and it tends to be relatively large compared to the actual size of the payments. By design there's no reliable way to tell the difference between change and the actual payment either.
Care to explain why not? What stops someone who mined 10k bitcoins in 2007/8 from cashing out. If I remember correctly, there was a guy recently on #startups freenode who showed everyone a screenshot of his wallet at $800k (one sec let me find it in my history) and claimed he mined them all really early.
They are definitely a handful of people who have over 10k bitcoins, but they're not storing it on an online blockchain.info wallet (which is where that screenshot is from). They're also not showing it on IRC.
That kind of screenshot can easily be produced by changing a little HTML on a 0 balance account.
Just to note: it did say there was no sound in Safari, but it was silently edited after the comment edit/delete window on parent ended. Odd you can't even delete comments that no longer apply after the edit window.
this is the effect of the scarcity of bitcoin.
there's a tremendous network effect, more and more online shops accepting them as well as AFK.
it allows much lower fees and risk than credit cards with their 3% plus chargebacks, up to 5-10% better margins for sellers.
Original creator here, it plots all the transactions it receives from Blockchain.info. It's more or less pulling from the same recent transaction feed that you get if you go to Blockchain.info's homepage. I'd like to think this includes all transactions on the network :)
