currency convertion

[michael low]

as a private invester who is planning to buy abroad are companies that convert your money at a buisness rate safe

[Imagine]

They should be safe, yes.

Whenever i need to know a rate, I use www.xe.com , which seems very professional. They convert money at a business rate too - the link is https://www.xe.com/fx/ .
The FAQ's about security etc. can be found at https://www.xe.com/fx/faq.htm#secure .

Good luck!
