http://de.wikipedia.org/wiki/Isopropanol listet übrigens beide (R+S / H+P) auf.

Irgendwie suche ich immer gleich wenn in diesem Forum was Chemisches angeboten wird wozu das Junkies oder Waffenfans brauchen. Offenbar kann man Isopropanol zur THC Extraktion verwenden (organisches Lösungsmittel, hoher Dampfdruck, rel. ungiftig)... also diese Mal wohl eher was für die Junkies, nicht die Gun Nuts (wobei man damit sicher auch gut einen Lauf reinigen kann).

R und S Sätze wären eventuell auch interessant zu erwähnen.

MtGox is not Bitcoin, but the topic here is about MtGox, not Bitcoin, right?

Ripple can be (and likely will be) made decentralized. If you currently have an issue with this, please check again in 1 year and then let's see who is more decentralized: MtGox or Ripple.

In Bitcoin you send something that has 0 value but can be sold if someone else wants to give you something for it.
Ripple lets you trade debt instead that might go bad etc. but that has some value. You might however have a hard time finding someone who accepts that debt, depending on who has issued it.

MtGox works rather like Ripple, once you transfer money to them, they issue "MtGox-USD" and "MtGox-BTC" debt to you that can be traded and redeemed for fees. If you buy BTC there, you actually did NOT trade BTC, you bought debt from MtGox towards you in BTC. You don't get anything of this value actually credited until you decide to settle the debt and force MtGox to send you the BTC to your wallet. Until then you only send/own/trade debt.

Ripple is not really a currency (XRPs are more like postage stamps than a "coin"), it is more of a decentralized exchange software and system. It makes more sense in comparing it to MtGox than Bitcoin.

Ah, danke für den Hinweis. 

BitPay zieht aber Fiatgeld ab und liefert BTC...

Zur Preisstabilität: Die kommt mit Volumen. Wenn man ein paar Milliarden braucht um den Preis zu bewegen und nicht ein paar 1000 oder 10000 dann wird's auch einfach in BTC anzupreisen. Sucht euch doch mal eine "echte" Währung mit einem ähnlichen market cap raus und dann schaut mal wie die so schwankt...

All an CC exchange could offer is to lock a transaction for 121(?) days to the customer. If there's no chargeback, it goes through, if there is one, tough luck -the lock can be still revoked by the exchange until then.
The risk for chargebacks is the same after 100 days and after 10 days, so I'm not sure what the trading should accomplish other than users scamming each other and not the exchange.

If somebody wants Bitcoin for "the long run" something like this might even be enough - yes, 4 months is quite long but better than no way at all to buy with CC!

I'm still wondering if it is feasible to do the following:

Instead of signing up with BitPay, emulate their way of operating by signing up on some exchanges, depositing some USD and BTC on each and use their API to automatically trade.

Once the payment API gets included in the bitcoin clients it should then be possible to accept bitcoin payments like this (e.g. a 100 USD payment with ~100 USD/BTC prices):
1) get current market average, add a few % for slippage - in this case request 1.05 BTC from the client and a payback address.
2) put a market order for 100 USD on the cheapest exchange - fees and etc. included it costs you 0.99876521 BTC
3) mark the payment as confirmed in your system
4) send back the 0.05123479 BTC change to the user and the 0.99876521 BTC to the exchange to top up the exchange account.
5) mabye even send a signed statement to the user that you exchanged at 0.99876521, so he knows which rate was actually used.

You'd only have to pay BTC network + exchange fees and users might have to trust you with a slightly higher amount than they need to pay for a minute or so. The whole script etc. can be open source, all secrets you'd need to enter would be deposit addresses for exchanges + API keys. For merchants selling BTC it could work the other way round as well, though you might need coloured coins or Ripple to automatically track irreversible USD transfers.

There is already a library in the works that combines APIs from several exchanges. Am I missing something or is the missing thing really just some glue between already existing parts?

If traders can switch their loans... can lenders re-lend loans too in the future?
E.g. I see a very cheap loan on the market, borrow the money and put it out there for a higher interest rate. I would be more than able to pay the lower interest for the loan anyways...

Gateways könnten z.B. sowas wie die bestehenden Exchanges sein (Bitstamp ist das z.B. schon jetzt) oder eben Banken etc.

Ist aber eher off-topic, ich find's nur irgendwie fast traurig, dass offenbar so wenige Leute hier, besonders im englischen Teil, Ripple verstehen (wollen). Das System hat fast noch mehr Potenzial als Bitcoin und kann mit beliebig vielen Währungen umgehen, darunter eben auch Bitcoin. Zusätzlich sind die Betreiber Bitcoinfans, im Gegensatz zu diesen "Mintchips" aus Kanada.

Bitcoincharts seems to have the largest independent (well, archived from the Gox ticker) historical database that I know of, available trade-by-trade as CSV. Maybe you can work together with them to also get access to the other exchanges' tickers.

I'm not sure if that is even needed.

A coffee around here costs... well, guess what - it won't matter to you, as you are far from my country. Selling a coffee won't change anything in Spain. Logging trades between me and local coffee shops might be an interesting task but ultimately it's neither me nor the coffe shop who creates and dictates the price of coffee.

Unless your partner uses digital money that can be externally verified (or rather publicly, as all bank transactions are anyways externally visible to various agencies) like coloured coin or Ripple, you won't be able to gather any meaningful data for trades. Also volumes in street shops would anyways probably be neglectable. If a shop owner acts as "wholesale" salesman of Bitcoin, he probably anyways logs a larger trade at an established exchange, and sells the coins later for a small profit if possible. If he could make a large profit, others would probably rather also buy online and he wouldn't sell at a loss very often. I don't see a lot of benefit on logging trades there.

Also: What about fees? If the shop owner seels the coins via credit card, he has a certain fee on top of that - who pays it and how do you log it?

Ähm, Bitstamp ist auch in der EU und auch im SEPA Raum - die sind in Slowenien daheim.

Bitstamp, Bitcoin.de und Bitcoin-central sind die derzeit verbleibenden 3 größeren Exchanges in Europa, eventuell noch Virvox (die mit den LindenDollar) aus Wien wobei die von den Fees her heftig sein dürften.

Die soll man auch nicht per Drag&Drop auf das Fenster ziehen sondern anstelle der leeren, neu generierten Wallet im Datenordner von Bitcoin einfügen.

Und "1337" im Username! Der kommt sicher frisch vom MIT!

Wozu dann jetzt einen Thread erstellen, wenn du eh erst frühestens in 2 Wochen was dazu zu sagen hast?

Why do you think miners are the ones cashing out? Yes, you need to pay for electricity, but for a lot of miners that's probably just equivalent to buying a certain amount of coins for USD every month... at rates that people on exchanges can still only dream of.

Well, collecting prices from OTC trades might be the smaller problem... already on localbitcoins people are getting mugged + robbed here and there. Announcing to an anonymous crowd your exact location and that you will carry larger amounts of cashor digital money that is equivalent to cash is not a smart move in my opinion.

I'm not sure if you get me, but "6 blocks" is an arbitrary number and probably only in bitcoin-qt because it equals 1 hour of blocks. It is in no way necessary or any indication that a transaction is neraly impossible to double spend. 6 blocks on a 1000TH/hour 1 minute block chain are far easier to double-spend than 2 blocks on a 1000TH/hour 10 minute block chain.

I would recommend to rather look at the amount of money it would approximately cost to double spend a transaction. For example a 1 GH/s miner costs 100 USD initially and 1 USD per day in electricity --> calculate how many of these you need to match the network hash rate and how much they cost to operate for a certain time frame. Then after e.g. 10 times your transaction amount was already spent on mining after the first confirmation, you consider the transaction finalized, as it would not make any economic sense to scam you that far down the chain. You then can calculate how many blocks this would mean approximately. On a faster chain this would mean more blocks than on a slower chain, everything else equal.

Bitstamp soll auch recht flott sein, gehandelt habe ich aber zwischen USD/EUR und BTC eigentlich noch nie direkt...
