The customers surely have standing to sue Binance. But to close the gap between what you feel should happen and what could actually happen… exactly what crime could they be prosecuted for?
> exactly what crime could they be prosecuted for?
Note that “crime” has a specific definition in law. You don’t have to be a criminal (commit a crime) to be rightfully sued, civil suits are a thing.
Anyway, your parent comment already answered the question, they would be sued by negligence.
What would they sue for? Nobody lost any funds.
