NCR Silver integriert ab November 2014 Bitcoin in ihre Kassensysteme.
In Zukunft wird es damit möglich sein, mit Bitcoins in Tankstellen, Supermärkten und anderen Geschäften zu bezahlen.
Zudem wird es überall dort möglich sein, auch Bitcoins in Fiat-Währung zu tauschen (und umgekehrt).
Ein weiterer wichtiger Schritt auf dem Weg zu weltweiter Verbreitung und Akzeptanz.
Prognose: Bitcoin-Automaten (ATM) werden zunehmend uninteressant, wenn der Umtausch an jeder Kasse erfolgen kann.

really still noone?
Did the new client 0.4.0 come without any changes to the API?

Hello,

where can I find a list of JSON-RPC commands supported by the current version of the bitcoin client/server?
(The "old" list (for v0.3.24) was here: https://en.bitcoin.it/wiki/Original_Bitcoin_client/API_Calls_list )

Thanks in advance!

The opportunities seem to persist:

Currently I can see the following opportunities:

b7USD => britcoinGBP
1. Buy 1 BTC at b7USD for 16.2 USD
2. Sell 1 BTC at britcoinGBP for 16.95 USD
3. Win the difference (0.75 USD)

b7USD => thUSD
1. Buy 1 BTC at b7USD for 16.2 USD
2. Sell 1 BTC at thUSD for 16.9 USD
3. Win the difference (0.7 USD)

b7USD => bitomatPLN
1. Buy 1 BTC at b7USD for 16.2 USD
2. Sell 1 BTC at bitomatPLN for 16.72 USD
3. Win the difference (0.52 USD)

I am not sure that the "window is now closed".
How should that have happened? Someone using an automated arbitrage software?

Hello,

sometimes it seems possible to buy BTC at one exchange and sell it immediatetely at another one, making some arbitrage profit.
Of course, we have to take differences in the currency exchange rates into consideration, too.
Therefore I have launched a site showing those arbitrage opportunities:

What do you think about it?
Comments/suggestions are appreciated!
Have fun,

Hi,
I spent several hours in this forum without having a username. Now I'd like to post a link to my recently launched Bitcoin-related website ("arbitrage opportunities"). Please whitelist my account.
Thanks in advance.
