Do receiving addresses keep on rotating or are they never re-used?

Remember that those receiving addresses are ALWAYS still good if someone happens to send you coins to one of those addresses again. Electrum will use them once and move to the next one just to help you remain "private". There is no security risk at all to using any address multiple times. Privacy may be impacted if an address gets used repeatedly, but it doesn't mean anyone can get to your coins in any way. That is the logic behind the software!

Thanks! Good explanation!

One reason to use an address repeatedly is during testing and verification of a system.

This may be developmental, or it may just be you - trying out a new piece of software. Like ....

0.001 btc --> address X,wait until it clears.
0.010 btc --> address X, wait until it clears.
1.000 btc ---> address X, wait until it clears.

You get the idea. minimize risk.

Ah okay so this list of 16 addresses will never have an earlier used address back in it?

It shouldn't, although the definition of "used" is a bit ambiguous.

No, new ones will be generated when one is used.

My question is this:

I have an Electrum wallet and I have a list of 16 receiving addresses. I think everyone has that obviously. But my question is, are these 16 the same forever? Whenever there is a new receiving address appearing in my Electrum then will it just be one of those 16 always (in turn one by one and after that get back to the first one and start the row all over)?

Or are these 16 continually new never used before addresses and did I just not notice that they were different each time?
