It all depends on the tasks at the moment, if i need to send money from one exchange to another then basically i choose usdt and if i need to keep my savings for a shorter time then i choose USDC. I hardly use BUSD...
Why i couldn't Saving use USDT. USDT Currently Fully Safe. What was a legal problem a few days ago is no more. You can use Usdt for saving or exchange anything. Now its have few tx fee. Its can save us insane fee another token.
