Bitstamp is a bitcoin exchange based in Luxembourg. It allows trading between USD currency and bitcoin cryptocurrency. It allows USD, EUR, bitcoin, litecoin, ethereum, xrp or bitcoin cash deposits and withdrawals.
The company was founded as a European-focused alternative to then-dominant bitcoin exchange Mt. Gox. While the company trades in US dollars, it accepts fiat money deposits for free only via the European Union’s Single Euro Payments Area, a mechanism for transferring money between European bank accounts. Deposits via credit cards or wires incur a fee.
Bitstamp offers an API to allow clients to use custom software to access and control their accounts.
