Das Problem sind doch eher investitionsfaule Banken, die lieber am Kapitalmarkt zocken als Kredite an Unternehmer zu vergeben, nicht die Leute mit Sparbuch daheim!

If this ever happens, please pre-announce it - because then I want to get out of there as fast as possible.
why?
how many % of Stamp's volume es actualy coming from Finex?
I guess a lot

Why do you need to guess? Bitfinex offers an overview over their trades + volume via their API... I don't really care how much they trade externally since it was suggested that they only trade internal.

Anyone?

Or does everyone else have better means to obtain coins?
Depends on your preferred methods of paying.

VirWoX is the only exchange that accepted PayPal and credit cards now for _years_. You pay a premium for that of course.

In the case of 0 fee txs sure they could just add their own (am not trying to help out 0 fee txs) but why would you do that if you can include txs that are paying a small fee?

Currently people even paying the minimum fee are waiting hours for confirmation due to the backlog which is due to the fact that miners are not going anywhere near the 1 MB limit.

EDIT: I see the point about "gaming" this and at this stage I don't have a good idea about how to stop that (although maybe ignoring 0 fees txs could help).
You can include fees too, though then you risk loosing the fees if you get forked off by other miners. Blocks that are not full would just get stuffed with "padding transactions" to win in fork situations, and more complex transactions would need an even higher fee, as they decrease transaction density.
1625  Bitcoin / Development & Technical Discussion / Re: Could preferring blocks with more txs help solve the small blocksize issue? on: November 22, 2013, 01:47:56 PM
Well, then you only incentivize miners to fill their blocks with as small as possible transactions using their own coins (with 0 fees) up to MAX_BLOCK_SIZE. This way it might be even better to reject a transaction and include 2 of your own instead. Also MAX_BLOCK_SIZE would be then EVERY_BLOCK_SIZE...

Of course that won't happen overnight, still it gives this incentive.

Naja, so ähnlich - Rot: Der Preis zu dem als letztes in der Zeiteinheit gehandelt wurde war niedriger als der Preis zum dem am Anfang gehandelt wurde, Grün umgekehrt.

Bitcoincharts z.B. bekommt gar nicht mit, ob verkauft oder gekauft wurde, der Markt kann auch ohne Handel wandern. Das sieht man schöner bei Aktienbörsen, die ja einige Stunden pro Tag dicht machen und dann einen anderen Eröffnungskurs haben können als am Vortag geschlossen wurde, weil z.B. dann in Singapur große Nachfrage war oder so.

P2Pool, aber da ist es schon recht schwer, einen "Kübel" auf das Band zu kriegen...

Kraken seems to be one of the most promising partner opportunities. This won't help with the Bitstamp situation directly, but might reduce risk.
1630  Local / Trading und Spekulation / Re: Kraken Now Open for Germany on: November 22, 2013, 01:26:17 AM
Question to Kraken people: Did you actually fix your API yet, or does it still give out wrong (binned/inexact and thus incorrect) trade data?
1631  Local / Mining (Deutsch) / Re: Unterschied zwischen PPS und PPLNS on: November 21, 2013, 11:44:11 PM
PPS =  theoretischer Wert eines Hashes (bzw. von einigen Hashes, die theoretisch für 1 Share nötig sind) praktisch ausgezahlt, daher keine Varianz im Auszahlungswert (aber natürlich in der realen Auszahlung, da du ja immer noch zufällig verteilt Shares findest)

PPLNS (Pay per last N shares) = Alle BTC die gefunden werden, werden auf die letzten N shares aufgeteilt. Damit kann man ein Share abliefern und nie etwas dafür bekommen, das wird aber statistisch dadurch wettgemacht, dass es Shares gibt, die mehrfach bezahlt werden.
Stell dir das vor wie ein Fließband, auf das du Kübel stellst und wenn jemand einen tollen Kübel zufällig erwischt, werden über dem gesamten Fließband Goldmünzen in die Kübel geworfen. Es können immer nur z.B. 100 Kübel zugleich am Band stehen, je mehr davon dir gehören, desto bessere Chancen hast du auch was abzubekommen. Selbst wenn du aufhört Kübel draufzustellen, dauert es einige Zeit bis dein letzter Kübel das Band entlanggefahren ist und so lange kannst du sogar noch verdienen, ohne einen Finger zu rühren. Allerdings hast du dafür schon mal gezahlt, und zwar am Anfang, als du den ersten Kübel aufs Band gestellt hast und das noch voll mit lauter anderen Kübeln war, obwohl du dann mit der Zeit im Schnitt 10 Kübel am Band hattest.

Kübel = Eimer btw. Tongue

Soll es eher in den wirtschaftlichen oder in den Informatikbereich gehen?

Spannend wäre z.B. eine Heuristik, in die man eine Addresse eingibt und die dann weitere Addressen ausspuckt, die vermutlich dem Inhaber dieser Addresse gehören. Da es ja einige Sonderfälle gibt (z.B. Laundering mit CoinJoin) reicht es nicht (mehr) nur darauf zu achten, ob es Transaktionen mit Inputs von anderen Addressen gibt. Es gibt auch weitere Möglichkeiten um das dann zu verfeinern, z.B. erstellt man erst Cluster und schaut dann wie diese mit anderen Clustern interagieren - wenn es innerhalb eines Clusters dann starke Wechselwirkungen zwischen einem Teil gibt und ein anderer Teil stark woanders hin tendiert, wurden die Coins eher gemixt als gemeinsam verwendet.

Wenn du eher was wirtschaftliches willst, wäre es z.B. interessant zu erforschen, welche Exchange zu welcher Zeit den Preis angibt - Zieht Bitstamp nach, weil MtGox hochgeht, oder umgekehrt? Ist es eventuell nur eine kleinere Exchange wo ein Panikverkauf auf einmal Auswirkungen auf andere hat? Welche Rolle spielen die Chinesen wirklich? Daten zu allen trades auf quasi allen Exchanges gibt's auf bitcoincharts, die Wahrheit ist irgendwo in den csv Files versteckt!

Auch spannend wäre es, herauszufinden, ob man aus der Blockchain den Preis vorhersagen kann - werden plötzlich Coins nach MtGox geschoben? Geht die Aktivität vor einem Crash hoch? Runter? Welche Indikatoren sollte man sich dafür ansehen - Anzahl der Transaktionen, Transaktionen ab einer gewissen Höhe, gewisse Addressen von denen man weiß, dass sie zu Exchanges gehören...?

Welche Ideen hattest du denn bisher? Dann kann man ja mal schauen, ob man was findet, das spannend und auch für die Community sinnvoll ist! Smiley
Toll wäre es übrigens, wenn du jeglichen Code (auch wenn er hässlich ist und eigentlich nur zusammengepfuscht) frei zugänglich machen würdest - Statistiken veralten schnell und gerne und es ist immer wieder toll, wenn man sich dann die aktuelle Lage ansehen kann indem man das Diagramm einfach mit aktuellen Zahlen füttert.

Das blöde an Ölkühlung sind immer die Kabel - in den Kapillaren kriecht Öl nämlich gerne mal entlang! Diese USB-Kabel werden nach ein paar Tagen oder Wochen am anderen Ende anfangen zu tropfen. Auch wandert Wärme da nicht sonderlich gut weiter, wenn man echt starke Hitzequellen hat, sollte man einen Lüfter o.ä. mit versenken (bevor jetzt die ersten Leute einen größeren Miner "einölen").

You could theoretically use Ripple as a way to provide liquidity on Bitstamp.
By purchasing BitstampUSD with Bitcoins or other means and then depositing these into your account.
At the moment it is not possible in large scale, but it could be worth looking into.
Just a suggestion.

Ps. Not sure if the actual liquidity it would provide is so low that it is not worth the effort but it could be worth looking into.
The liquidity is not there at the moment, but if you put in the orders in large quantities, they will be noticed. Liquidity is a chicken-egg problem and can only be solved if you actually do something against it.
Ripple is a small community which has its benefits too - if you put in a learge announcement, that you are going to make the market on Bitstamp USD and really follow up on this, anyone active in Ripple trading will know.

Anyways, the bigger issue I see is that it might be a bit hard to justify buying USD.Bitstamp with BTC - after all they want to transfer only USD, and not do trades (they could easily sell BTC on Bitstamp for more USD - the problem is that they are not theirs!). Working with a local gateway (there are 3 or 4 major Chinese Gateways offering CNY IOUs) might work though, especially if you then make the market by offering exchange rates towards Bitstamp.USD that are competitive. It might at least be worth a shot - in general either they do it behind closed doors or they are really too risk averse when it comes to trying out a few new things like trading a couple 1000 USD on Kraken or Ripple or re-opening the MtGox bridge once more for selling fiat to have more depth on that end...
1635  Economy / Exchanges / Re: [OFFICIAL]Bitfinex.com first Bitcoin P2P lending platform for leverage trading on: November 21, 2013, 05:33:26 PM
I guess Bitstamp has other things to do than setting up a collateralized loan contract with an entity in Hongkong(!) collateralized with internet funny money (as far as lawyers are concerned).
1636  Alternate cryptocurrencies / Altcoin Discussion / Re: Any news from Ripple? on: November 21, 2013, 05:26:30 PM
Bitstamp and probably soon Kraken are gateways that are well known in Bitcoinland... and there are 3-4 smaller ones as well. Stale prices can easily be exploited with arbitrage bots, there is actually quite some money to be made, especially on the Bitstamp markets.

The biggest issues is still that people think of Ripple as a coin and not an exchange/payment mechanism. I agree the volume is not huge at all, still it is better than nothing and it is fairly nice to work with compared to some other exchanges that seem more erratic from time to time.

I'd recomend using a local rippled and client by the way, if you want to do any serious trading - the "official" servers are overloaded from time to time. That's the main point about using a distributed exchange anyways.
1637  Economy / Exchanges / Re: [OFFICIAL]Bitfinex.com first Bitcoin P2P lending platform for leverage trading on: November 21, 2013, 05:19:23 PM
He won't lose any money in slippage if he puts up a limit order (it might sound imbecile to some, but most people do place market orders, including the ones that think it's imbecile).
People rarely change defaults... how about as a first step making the default a pre-filled limit order routed only to Bitfinex? It would be nice to set the "only to Bitfinex" default to something else in the account settings of course. Not claiming a BTC for that one, but if you think people just quickly clicking buttons are a problem, do something about it!
1638  Alternate cryptocurrencies / Altcoin Discussion / Re: Any news from Ripple? on: November 21, 2013, 05:05:54 PM
Ripple != XRP. You can not buy "Ripple", it is a protocol.

30 day volume is at about 8k BTC towards XRP, about 500 BTC towards USD, total volume (in other currencies, USDXRP for example is also quite strong with 660k USD traded in the last 30 days) should be around what BTC-e does in Euros, looking at http://bitcoincharts.com/markets/.

They are hiring like crazy and also on the development front quite a bit is happening with an iPhone app and a Java client library being released. (https://github.com/ripple/)

The Great Bitfinex Game!

1) Bitfinex will pay a bounty of 1 BTC for anybody that comes out with an idea that actually makes sense in order to improve our liquidity on Bitstamp
2) Anybody that will post an idea that is flawed, doesn't make sense, will never work for the reasons I will be honored to explain or just say things like " why don't you transfer to Bitstamp more money if 2 millions a day is not enough" will have to pay 1 BTC cent to the address:
1J14J1ZR11CsFKXyhneXpfVBp34ovQuh7C

All the coins collected by this game will be donated to www.seansoutpost.com , a homeless outreach in Florida accepting bitcoins.

Allow deposits of funds (especially USD) directly on Bitstamp instead of having us wire them to you. If Bitstamp doesn't allow that directly (haven't checked in a while if I can transfer funds to another Bitstamp account on their platform), go via Ripple for example - it works there for sure and you have an account on there already for months anyways. Time to use it.
If KYC etc. is the problem, just don't credit the balance until the user is verified or only offer this option to verified users. You can also bounce the payment on Ripple...

Well, if you only need to involve 3 parties (actually maybe 4, as the Bitcoin block chain is also a party in this, although very transparent concerning trust), you can already use the platform I hinted about... it's good enough for me. The parties involved for a BTC trade are: BTC blockchain --> web wallet funds storage (in BTC) --> distributed exchange --> web wallet funds storage (in USD) --> whatever payout method is supported by the web wallet funds provider (e.g. SEPA, PayPal...). These providers might need a license as e-money issuers in most western jurisdictions, but not as money exchangers as all they do is issue a balance on the distributed exchange, not do the actual trading.
Currently the fund storage on both ends as well as the trading engine is supplied by 1 single entity (e.g. MtGox) which is likely what you want to overcome. Most likely there will still be a need to give away funds to a trusted third party and to trust the same or another third party to release funds on a different channel unless there are ways other than cash to truly send fiat money that you own and that is not at a service provider (bank, paypal, dwolla...) electronically without ANY POSSIBLE way to withdraw the transaction after the fact.

The actual other person on the other side of the trade is abstracted away, since I don't know or care about her, only about the offer that is put on the distributed exchange.
