41  Economy / Trading Discussion / Tradehill market data on: June 13, 2011, 12:42:50 AM
Currently the chart on the site is more or less useless (thanks to the 2 jerks who put up the 500/1 and 999.9/2 asks... -.-')
Does anyone already have something like mtgoxlive mashed up on a quick website? The charts on bitcoincharts might look nice, but they don't really show individual orders on mouseover, one of the features I love most about mtgoxlive...
42  Economy / Trading Discussion / [Fun] Songs fitting to BTC exchanges on: June 12, 2011, 12:36:05 PM
MtGox: "That circus music" (http://www.youtube.com/watch?v=_B0CyOAO8y0) Makes a great background music to the spikes from 10 to 20 USD within a few hours
Tradehill: Stop and stare (http://www.youtube.com/watch?v=HtNS1afUOnE) As the people there seem to rather put up some very conservative trades instead of really trading.
Britcoin: Englishman in New York (http://www.youtube.com/watch?v=d27gTrPPAyk) Trading in GBP in an USD dominated currency. Cheerio!
Bitomat: Polish boyfriend (http://www.youtube.com/watch?v=GCkNV_UIF3g) Just because it's awesome!

Any others you'd like to add? Feel free to share! Smiley
43  Local / Deutsch (German) / Tradehill - MtGox Konkurrenz mit Eurohandel! on: June 08, 2011, 10:49:26 PM
Gerade frisch im allgemeinen Forum aufgetaucht:

http://forum.bitcoin.org/index.php?topic=13650.0

Offenbar habe sich ein paar "alteingesessene" Bitcoiner es nicht nehmen lassen, eine Konkurrenzplattform zu MtGox aufzustellen, und nach kurzer Durchsicht bin ich erst mal sprachlos!

Einige Sachen (z.B. API!) fehlen noch, allerdings bieten sie jetzt schon einige sehr tolle + wichtige Features an, wie Handel in zig verschiedenen Währungen(!). Auszahlungen sind derzeit immer noch Dollarlastig, man kann aber sogar iTunescodes oder WoW-Gametime kaufen... scheint recht Zielgruppenangepasst zu sein, das Ganze! Wink [Edit: Heutzutage [20.6.] schon lange nicht mehr... wird ja vielleicht wieder kommen, wenn sie mit dem aktuellen Ansturm zurecht kommen]

Interessanterweise gibt es auch noch ein Referralsystem mit 10% Rabatt für Leute die einen Refcode bei Accounterstelliung verwenden (laut https://www.tradehill.com/Support, Unterpunkt "Fees and Commissions") und ich nehme mir gleich mal die Freiheit heraus, mit meinem "nur 4-stelligen" Refcode zu protzen (ich nehme an, die werden sehr bald fünfstellig werden...): TH-R1138

Leider habe ich die 1337 um genau EINE EINZIGE STELLE verpasst! Angry [Edit... ja, es war spät... :-[]

Naja, sei's drum - und wie immer gilt: Man vertraut dem Betreiber sein Geld/Bitcoins an! Also Vorsicht und Augen auf, nicht gleich wie wild die neue Yacht verpfänden und das Geld nach Chile senden! Lieber etwas vorsichtig handeln und mal schaun, was da draus wird.
44  Other / Obsolete (selling) / [Service] Getting torrent files from demonoid on: June 04, 2011, 08:39:02 PM
As Demonoid is a quite open tracker, and only it's torrent files are protected, I'm offering the following service for a donation of your choice (please be reasonable and refrain from sending out single Satoshis, k?):

You send me a link to a torrent on demonoid (like http://www.demonoid.me/files/details/2620536/14601186/) either in this thread or via PM + tell me how much you have donated. As soon as I get back online and have confirmed your donation I will download the torrent file and upload it on Rapidshare or a similar filehoster and send you the link to this.
This will save you the hassle of creating an account, if all you want are 1 or a few files off demonoid.

Also I'd like to remind you of the principle of "seeding" - BitTorrent relies on giving as much as taking!

Happy torrenting, and I hope this is of some use for you!

Donations go to: 1FtD3L6aq95qqaH759SnorcsvPPSw4sw7B
45  Bitcoin / Mining / ATI HD 6670 Series - anyone got hashrate data? on: June 03, 2011, 11:00:50 AM
As these cards are still missing at the moment at https://en.bitcoin.it/wiki/Mining_hardware_comparison maybe someone who has one of these GPUs could run some quick tests?
Expected would be something in the 100-150MH/s range.

The reason why I'm interested is, that these cards are also available as passive versions, so with a silent fan, these should be able to run 24/7 at much better noise levels than some of the hairblowers out there.

Really great would also be power draw (measured via a "Kill-a-watt" or similar wall plug devices), but hash rate is priority #1 for me atm.

Thanks for any data, let the testing begin!
46  Other / Obsolete (buying) / [closed] WTB Settlers 7 on Steam (Europe) for 2 BTC on: May 24, 2011, 10:55:55 PM
http://store.steampowered.com/app/901436/

As today this game is half price, I'd love to buy it and would give out 2 BTC for that.
Only prerequisite is that it works on Steam in Europe (I have no idea of there are differences between areas).

Just contact me here or via PM, you'll get my mail adress and can send me a "gift" - I'll pay you as soon as it could be verifiably added to Steam.
Should you have a key code for this exact version (Deluxe Gold Edition) floating around, I'd be happy to buy this too instead.

Deal?
47  Other / Obsolete (buying) / Buying Shogun 2 on Steam (Europe) for 1.5 BTC on: May 23, 2011, 07:42:42 AM
Hi there,

As many people have steam codes with their ATI Graphics cards, I want to buy 1 (only 1!) of them from you.
Only prerequisite is that it works on Steam in Europe too (I have no idea of there are differences between areas).

You send me the code + BTC address, I test it (if it works out on Steam), I send you 1.5 BTC if it worked or will delete everything related to that code (you'll have to take my word for this...).

Deal?
48  Economy / Marketplace / [GLBSE] Suggestion: Proof of money when creating shares on: May 16, 2011, 07:45:49 PM
Hi everyone,

My concern is that currently on GLBSE you really can become a bitcoin billionaire easily:
Create a billion +1 shares, sell the one share at 1 BTC --> poof, here you go!

What I would suggest is that when creating shares, you also yourself have to buy as many shares as you would like to keep. As the money goes right back to your account, and there are no fees, this would not harm any business. It would however stop individuals that abuse a share model to create a credit/speculation system, where they only fundraise from others - but solely based on a big bubble (as the suggestion in the beginning, which is not possible at all with less than 7 million bitcoin in circulation right now and 21 million BTC max.)

I would like to have a second kind of shares that is working like this.

Example:
I have 100 BTC I'd like to start a business with, however I need another 200 BTC to get going. With my proposed kind of shares, you would only be able/allowed in the beginning to own 1/3 of the shares. The ability to buy more shares gets frozen until all shares are sold or until I have more money in my GLBSE account than initial shares + currently sold shares are worth (and I would be able to buy shares only with that excess money of course). Once the remaining 2/3 are sold, I can buy them back at market price as I like or really start that business I want to do.
Should I hold 2 assets at once, of course these numbers would be cumulative (so I have to have enough money in my account for both assets + sold shares and can then buy additional shares back with the remaining money).

This would not allow for every kind of business, however it would be a more secure way to start something, as you need to give proof that you already have the money you claim to have and get also only the proportion of the shares that is equal to your own investment.
For the more risk-friendly investors they could still invest in the "classic" shares - for shared mining contracts (as a concrete example) however something like my suggestion might be more desirable.

Maybe something like this could even be done right now, by releasing all shares and immediately buying back your own part, but then the asset holder could also double-spend (and I'm not even sure if it might work in the first place for this very reason...).


Hope you like my idea (or even better: You don't like it and give constructive reasons why and how it could be made better!), looking forward to your input.
49  Bitcoin / Development & Technical Discussion / Possible attack: Difficulty DoS on: May 14, 2011, 02:36:45 AM
I'm not sure if this attack scenario already came up:

If someone posesses enough computing power to push the difficulty to a level that is far beyond the current level, this might cause the network to collapse. It might be nearly impossible after the attacker leaves the network again 2016 blocks later to discover/solve any block, so the next 2016 blocks might take ages or be never found if miners give up their business. So - is a difficulty manipulation attack possible in bitcoin (theoretically) - or are there some countermeasures that could be taken?

Just imagine for example "back in the days" when you could only do CPU hashing if somebody would suddenly drop in with a few dozen GHashes/s, solve lots of blocks in nearly no time, push the difficulty to 50 000 and disappear again. With 3 MHashes/s this would on average mean to get a hit about every 2-3 years. Even if the whole network has ~1 GH/s even a simple transaction would need 1 week to be confirmed.

In an early adopters/enthusiast community this might be ok, but later on (as it is expected somehow that difficulty might fall again when the income from BTC generation gets less and less and the few bitcents from transaction fees get more and more interesting) this could pose a real threat to the network.
