I have a few TronLink wallets with USDT (TRC20) but no TRX in them.So I’m trying to figure out the cheapest or smartest way to do this.Option 1: Use Only TRX (No Energy Rented) but it expensiveOption 2: Rent Energy + Use Minimal TRXand I heard there are smart contractsOption 3: Use Smart Contract ❓ My Questions:What would you recommend as the cheapest and safest method in 2025?Is there any way to fully drain a wallet to $0? Even with good estimates, I think I’ll always leave some dust TRX in each wallet that I can’t transfer due to gas fees.
