Hello! It does not require monthly contribution! 🙂 Every SSB issuance happens every month with, - Min amount: $500 - Max amount: $100K (in multiples of $500) Do note that you might not be allocated the amount that you applied for! Example, you applied to play your $10,000 into SSB, on the results day, you might only be allocated $6,000?
