please provide more accurate information regarding this warning because this event is of great concern to all cryptocurency users. so do not just talk nonsense without attaching a proof of a warning that you have conveyed. and if this information is correct then we all have to make withdrawals in several big markets that have our assets there. but I'm not sure if a big market doesn't have strong security.
