I have heard that you are not supposed to reuse your bitcoin addresses. I have been looking around to but have been unable to find any good information about this. I am interested in finding both the technical reasons for this and the practical implications.
At this point my understanding of the issue is that it is ok to reuse a recieving address(public key hash), but after you have spent any of the bitcoins then you need to generate new addresses.
Does this mean that if someone is making regular payments to me over a long period of time, I will have to send them a new address for each payment?
I am using the Bitcoin-Qt client, if I am going to send or recieve money multiple times do I need to take special steps to ensure security, or is this all handled by the client. I have noticed that the recieving addresses used before I spent money are still available for use, is this ok?
I am really confused about this issue, hope someone can make tis clear.
Thanks
