There are so many scarecrow opinion pieces lately about Unverfied Pi Balance!! Most are saying that everyone will lose the entire sum cumulatively gathered from security circle and referrals that have not verified their KYC (know your customer) but also from lock-up boosts.
The Unverfied Balance in Pi is made out of more than one thing. Pi mined together with referrals/security team, bonuses from being a pioneer and up, and the boosts from lock-ups at the first mainnet migration.
What will be lost from the Unverfied Balance are the Pi for which referrals and security circle members won't pass the KYC before the next mass migration to mainnet. With the exception of the last 6 months before this migration.
So the boosts and bonuses you mined yourself will be safe, and once the Core Team has finished putting the Unverfied Balance feature in order, everyone will gain access to the Pi available there.
