Quick question about the CPK. As I get more funds into my BBP wallet, do I have to occasionally send more funds to my CPK for them to be counted towards my coin age? Thanks!
Coin-age is required only if you are doing PoDC (Boinc). I assume you are doing that; so you are correct, only funds in the CPK address count towards PoDC coin-age.
Having said that, there is no reason to keep increasing your coins in the CPK address unless you are running short on collateral for PoDC (i.e., increasing RAC).
