The amount of veOGV you receive is based on two factors: the amount of OGV you stake and the end date (expiration) of the lock-up. A multiplier is applied to the OGV amount to calculate the resulting veOGV amount, and this multipler increases according to the length of the lock-up. In other words, the further into the future the end date is, the higher the multiplier. If two users stake the same amount of OGV on different occasions but their lock-up periods end on the same date, they will still receive the same amount of veOGV. The user who stakes earlier will accrue more rewards and be able to exercise her power earlier, but both users will have the same power once they have staked the same amount with the same expiration.
