It's not about their wallets which are empty.. It's about fraud that has happened, so all companies linked to Bankman should be liquidated (illiquid assets, properties etc), and remaining of funds should be returned to users. Also Cyprus SEC clearly say they cover up to 20k Euro. All Ftx clients are under this license, or else it would be illegal to keep︀ their account. But ofc there's a need for class lawsuits for all this.
