I am positively surprised they have chosen USDC and not USDT on Tron ;)

Heh, that's what happens when you suddenly have US peeps snooping into your stuff and making decisions. I think the conversion of the fund into USDC is great though.

Wait what happened? You mean because Binance got fined by the SEC, right?

Yes, probably Binance felt pressed to keep money in USDC which is ran by the US company and provides a bit more security than Tether
