The minimum /maximum withdrawal limit is for a single transaction only, indicating the minimum/maximum amount we allow you to withdraw for a single transaction for a given blockchain asset. You may check it on the withdrawal page of each coin you want to withdraw.
The maximum withdrawal limit is not necessarily equal to your daily limit (24h).
The daily limit can be raised while the maximum withdrawal limit is not to be raised.
If you want a larger daily limit you may submit a ticket.
