How to get my money back and rebuild trust in GRO?

Hello!

January 2022 I deposited some USDC (GVT was $170), GRO was integrated with Argent and seemed to be trustful and reliable protocol. But yesterday I suddenly discovered that GVT = $96.41 and I lost a lot of money. What to do? Help with some advice please. How can I get my money back and rebuild trust in GRO?

Thank you in advance.
