I’d like to better understand the concept of stake weight. I am aware that it takes 7 days for coins to mature to 100% stake weight. I would like some clarification about what causes the weight to return to zero.
-I buy divi from an exchange and send it to my wallet or someone sends divi to me
-I win an award from a masternode or from staking
-I send coins out of my wallet
Which of these actions brings my stake weight back to zero? Are all coins in my wallet always at the same weight? Are there other parameters that I have failed to mention that effect stake weight?
