You should have gotten it via mail when you signed up (created your account) on Bitfinex. It is different from your account password or anything else.

1584  Alternate cryptocurrencies / Altcoin Discussion / Re: [XRP] is Ripple a true crypto now, when open source? is it an alt-coin? on: November 26, 2013, 09:17:43 AM
XRP are still alt coins by definition and nearly every topic outside of here got derailed by people thinking the ONLY way to use Ripple is to use XRP or at least mainly XRP.

The OP seems to confuse this as well.

There is Ripple, a decentralized exchange, and "Ripples" (XRP), the native and only asset on there, which has some properties that are similar to BTC and other math based currencies that might make them a "currency" or "alt coin" depending on your definition.

Yeah, that's what I meant. Smiley

Thanks for including buy/sell! Are there some limits or pricing plans for the future etc. one should be aware of, or is the key request just so you can cut off potentially abusive people?

I really hope you include more exchanges over time by the way.

Also, is it ok if I pull data from you and store and process it further on my own?

Und ich dachte schon, die GPU-Racks von vor ein paar Jahren sehen beeindruckend aus...

Do you also offer individual trade data, like bitcoincharts?

...mit Verlust in EUR oder BTC? Wink

Gerade gegenüber den Preisen von September ist das eine eher wichtige Frage denke ich.
1589  Local / Deutsch (German) / Re: Bitcoin nicht als Währung geeignet, aufgrund zu starker Fluktuationen on: November 25, 2013, 06:38:22 PM
Naja, ich hab es schon auch mit einer Aktie verglichen - Geld ist immerhin am freien Markt. Auch Währungen (wie EUR etc) stehen nicht gerade stabil da, wenn man sie nicht mit anderen Währungen (selbst da gibt's immer mal Schwankungen) sondern mit Gütern vergleicht. Bitcoin ist nochmal "Metageld", weil es nicht mal Vorgeschichte hat und derzeit hautsächlich (wie Aktien) gegen Geld statt Waren gehandelt wird.

1592  Bitcoin / Development & Technical Discussion / Re: Maybe there is a possibility to discard unfitting hashes early? on: November 25, 2013, 01:13:39 PM
There are a few operations at the end that can be omitted as far as I understand, mining software does this already for years now though.

The problem is it takes very long until you really know or can at least reasonably guess that indeed there will be no 0 or a lot of 0s at a certain part of the hash.
1593  Bitcoin / Development & Technical Discussion / Re: Hardware accelerated bitcoind? on: November 25, 2013, 01:09:19 PM
Yes, I also assumed that it isn't maintaining operation but bootstrapping that is the main issue for the OP.

I read somewhere about ~60 million transactions in the block chain so far - with 15k checks per second that still takes 4000 seconds or a bit more than 1 hour, even if they are beamed directly in the CPU cache with no IO latency or overhead at all. I wouldn't call that very significant (after all it is checking all transactions in Bitcoin ever) but still there might be some potential for optimization, especially seeing how much people were able to speed up computations for SHA256(SHA256()) for mining over the years and ECDSA is to my understanding not even as complex but just uses larger numbers that are not easy to handle.

secp256k1_OpenCL would be a really cool thing to have and it might be worth it to explore this direction further, even if there are no direct benefits right now.

Yeah, I'm sure it's just a matter of "Oh, now we really need to focus!" and suddenly everything falls into place and the servers run smoothly! Roll Eyes

https://github.com/timmolter/XChange - just implement this instead, then you could even do automated trading.

Edit: Enabling people to abuse a free and very useful service is just what you might call a "dick move". Also a great way to get your IP banned...
1597  Bitcoin / Project Development / Re: Arbitrage Deal Finder on: November 24, 2013, 08:47:45 PM
Haven't checked the code, but I hope that you implemented something to ensure this:

Im Übrigen ist das der Ertrag rein durch neu erzeugte BTC, ohne Fees die an Miner ausgeschüttet werden - aber auch ohne Fees, die eventuelle Miningpools verlangen.

Da in 1 Monat bis zu 3 mal die Difficulty steigen kann (so wie derzeit aggressiv Hashrate online gebracht wird, scheint das so weiter zu gehen), würde ich max. 1 Woche berechnen oder den Monatswert aus nur ~20 Tagen berechnen.

Die Berechnung ist übrigens korrekt, aber das wurde eh schon gesagt. Smiley
1599  Local / Anfänger und Hilfe / Re: Trading Plattform mit Hebel gesucht ($/Btc). Bitfinex.com ? on: November 24, 2013, 08:21:18 PM
Nicht wissen, was da was bedeutet aber gehebelt handeln?! Shocked

Na dann viel Spaß... wirst schon wissen was du tust.

Den Hebel kannst du in den Account Settings (auf deinen Benutzernamen rechts oben klicken) einstellen, momentan ist er bei dir 2:1, Maximum ist derzeit 4:1 (10:1 ist illusorisch, wer sowas anbietet ist wohl eher im Betrugsbereich anzusiedeln). Die 1% sind die maximalen Zinsen, die du bereit bist, an diejenigen zu zahlen, von denen du dir die USD ausborgst um damit zu handeln. "Margin requirement" ist die Menge Geld, bei der du dann zwangsliquidiert wirst.
1600  Economy / Service Discussion / Re: Does bitstamp support trade in Euros? on: November 24, 2013, 08:08:49 PM
You could withdraw to EUR on Ripple and trade there against BTC issued by Bitstamp. I doubt there is much depth though and I also would love to see rather a EUR order book (either joined with USD or seperate) to not have even more currency risk.
