Yes, sure. When Lety-status is assigned, the total amount of cashback earnings is what matters, including withdrawals.
For example, you have cashed out 500 INR / 10 USD / 10 EUR / 40 PLN and acquired a LetyBronze status. To receive a LetySilver status, you need to save 3 000 INR / 50 USD / 50 EUR / 200 PLN more.
