If you stake SXP for the Swipe Slate Visa card you will get on-chain SXP staking rewards.
The rate in December 2020 is around 150 SXP per week (If total staking is 30.00 SXP), or 7800 SXP per year.
This means that you, by approximate 6 years, will have a full paid back staking requirement for the Swipe Slate Visa card.
NOTE: There are no guarantees since the on-chain staking rewards might change over time. However, if the reward is reduced is probably due to more stakers which likely would increase the SXP price.
During this time you can enjoy all the benefits, like 8% cashback.
