How many transactions can I send and receive from one address?

[citboin]

I was wondering how many transactions can be sent or received from a single address before that the private key might be compromised. I've been reading a lot about bitcoin, but can't seem to find information about how transactions are signed and how they remain secure after the first tx is sent.

Any info or reading is much appreciated! Thanks!

The address can be re-used as many times as you like without any issue of being compromised due to "usage" (re-use will reduce your level of anonymity though which is why it is generally best to avoid).

As most (if not all) wallets effectively randomly choose addresses to send from it is out of your control when any particular address is chosen as one of the tx inputs.

The potential problem wrt security is more to do with your wallet not being encrypted or your computer being keylogged (the other huge problem is not having or having correctly backed up your wallet).
