It keeps telling me to check my balance, when my balance clearly states that I have $50 USDT. ### 1/5 — Bad wallat *2025-06-01* I saw it on Apple app store and I downloaded it, I wanted to test it, then I sent 30 trc20 USDT and received 24 USDT then I wanted to send the 24 USDT out it wouldn’t allow me, it keeps saying check your balance, I think it’s a scam wallet.
