If the account has not been used for more than one year and the fund in the account is insufficient 1000, it will be frozen by the exchange and cannot be opened.

If you keep the minimum capital in your futures account, you won't sleep. If all the money was withdrawn at that time and there was no balance in the account, then it would be dormant after 1 year. Hibernation requires me to go to the counter of the sales department of the futures company with my ID card to activate it.
