Super, vielen Dank! Zum Margin-trading gibt es hier die Meinung eines Anwalts: http://www.frag-einen-anwalt.de/Differenzgeschaefte-mit-Bitcoins---f273826.html
Ich verstehe das so, daß man es genau wie andere private Veräußerungsgeschäfte berechnen kann, nur daß man evtl. ansonsten noch die Zinsen als Kosten absetzen könnte. Das finde ich aber erstmal nicht so entscheidend.

Großartiges Tool, vielen Dank. Hab gleich mal ein bißchen gespendet. Hast Du inzwischen schon was bzgl. open source beschlossen? Das würde es vermutlich einfacher machen, sowas wie bitfinex-support selbst zu implementieren. So bleibt mir nur, Dich darum zu bitten. Bitte, bitte!

OK, so it may have appeared that we didn't put much work in lately, what with no visible changes and no database updates for weeks. We're sorry, but the truth is, EVERYTHING has changed in the meantime, and we could hardly keep up with all the work that was necessary to make these changes.

So we are very proud today to present the new bitcoinprivacy.net! Please, check it out! The major new feature is the built-in blockchain explorer - no more links to blockchain.info! But aside from that ...

Not only does the site look nicer (bootstrap 3), but it is much more scalable, performant, safe and extensible, because we rewrote the entire thing in Play! framework with Scala. This will make it much easier to add new features.

We also felt we outgrew sqlite, so we changed to mysql, which caused us major headaches along the way.

And finally we have been on a new server for a while. This was intended to make development easier, but has uncovered lots of little problems that needed to be addressed. Addressed they have been, and we have learned a lot that should help us make BitcoinPrivacy even nicer even faster.

We hope you enjoy the new BitcoinPrivacy and give us some feedback!

thank you, grahvity.

bitcoinprivacy.net has seen another few rounds of improvements: we now have (mandatory) https (with a real certificate), the top 100 are now top 1000, a few new stats, and an entire new page:

Distribution of Bitcoin wealth: bitcoinprivacy.net/index.php/distribution.html - not only can you play and find out how many addresses own more than X Bitcoin, and how much of the total bitcoins this is: e.g., there are 311285 addresses with more than 1 bitcoin, totalling 13621839 bitcoins, 98.56% of all bitcoins. Did you know?

We also have finally implemented the one statistic that inspired me to start this project years ago: Gini coefficient (for addresses and for closures, too). Not surprisingly, it is astronomically high at about 0.98, even when capped at the dust limit of 546 satoshi.

All of these fine numbers continually updated about 1 hour behind the blockchain, of course. Enjoy!

We have long been inspired by http://bitcoinrichlist.com/ and have always wanted to generate a rich list of the top entities/address clusters (closures in our terminology) as opposed to single addresses. At http://bitcoinprivacy.net/index.php/richlist.html you can check out our results:

You can find the traditional address top 100 next to our unique closure top 100 of address clusters that seem to belong to the same entity (read the FAQ for details!). Note that unlike http://bitcoinrichlist.com/, our list stays almost up-to-date (as the complete site)! Moreover, if you compare the two sites, you will find that the addresses differ in some places (such as No 1 and 3). That is because we correctly identify and display multi signature addresses. As you can see, the age of multi signature has arrived in the top 100!

They're not quite live, because we are staying a few blocks behind in order to avoid reorganisations. But, they're there.
Plus, you might have noticed our new design, and there have been a plethora of changes under the hood. Check github for more on that.
So, what's next? We are working on some showcase examples that reveal interesting blockchain facts and trivia.  We'll keep you posted.

Today we are proud to launch the first official version of http://bitcoinprivacy.net, our contribution to making bitcoin a little more private for everybody. We have been working on the https://github.com/stefanwouldgo/Bitcoin-Graph-Explorer that powers this website for an astonishingly long time. Please take some time to read the FAQ and play around with the search function. If you have any suggestions,  let us know here or at info@bitcoinprivacy.net.

We are aware that our current offering looks rather humble, and there are many features we are planning to implement. Notice for example that the database is static at this point. Dynamic (near realtime) updates are among the highest priority items on our agenda. It shouldn't take too long. More involved goals include improved heuristics (think CoinSudoku!), and maybe some nice visualization tools down the line. Feel free to tell us what you would like to see!

I cannot login to my account anymore, and I get no password reset emails from you. I have sent an email more than an hour ago, no response. Please let me know you haven't vanished with my bitcoins, I am getting nervous.

http://bitcoinprivacy.net lets everybody search for addresses that seem to belong to the same owner. See what information you are giving away when you pay someone with or publish an address! Please read the FAQ for details!

Sehr schön. Komme auf jeden Fall auch, allerdings wieder etwas später.

Ich fahre heute abend mit dem Auto von Leipzig nach Köln. Bitte per p.m. melden, falls noch jemand mitfahren will!

Wer aus Leipzig noch mit nach Köln zur Konferenz fahren will, melde sich bitte bei mir per pm. Es gibt noch Plätze.

Fährt noch jemand vom Verband nach Köln? Ich fahre heute abend von Leipzig aus und könnte noch jemand mitnehmen.

ja, kenn ich. Ganz nett, wenn auch etwas teuer und in Scheußlich. Dr. Seltsam in Plagwitz ist netter und günstiger.

Da bin ich ja mal gespannt, ob ich Euch erkenne.

Wäre auch gerne dabei, kann allerdings erst ab 20 Uhr.

Congratulations! Great job. I had been working on something like this for about a year now, and after taking a break for a few months, there you go just making it true. Would you share some technical info on how you did it? I mean working with these huge data sets isn't trivial ...
