# Sustainability

Like all crypto projects, USDT Piggy Bank is sustained by the continued support of the community and our dedicated team. To provide a solid foundation for the growth of our players' investments, USDT Piggy Bank pays an average **daily return of 5%** according to the current mining efficiency rate. 

This rate rises and falls as you and other players hire piggies, compound earnings and pocket USDT, a feature which helps to prevent rapid draining of the contract and promotes **long term sustainability**.

To help grow and sustain the project, there is a 6% fee on deposits and withdrawals, which goes towards the continuous marketing and development of USDT Piggy Bank.

Additionally, we also offer a 10% referral bonus to reward users who share the project and help to grow the USDT Piggy Bank ecosystem.
