If I have the address A with 2 nodes, one with 5 CLAM and other with 3 CLAM; if I select the node of 3 CLAM and send it to another address, the age of node of 5 CLAM will be reseted ?
Thanks.
Addresses almost never matter. It's all about the individual outputs. Your 3 and your 5 are separate things with their own ages.
The client will probably merge them into a single output when either of them stakes, so you might want to keep them in different addresses. That will stop them being merged.
