There are many ways to earn CVP rewards, which may have a 10-week vesting period
While CVP is earned immediately it vests over 10 weeks from the moment it is earned.
Example: If you were to earn 10 CVP per day for 30 days by the end of the 30 days you would have earned 300 CVP, but not all 300 would be available for withdrawal. This is because CVP vests over a 10-week period after it is earned. So the last CVP that you earned on the 30th day would vest 10 weeks later.
