So I don't need to do anything? Will my assets remain in my account? Do I need to sell now and buy back later? I'm new to this pre-market thing?

$USUAL since a lot of people are asking , what happens when pre-market ends . When pre-market will end , trading will be stop for 24 hours. when spot trading will be started in next day, you can start trade again. you will find all your usuals exactly where they are now. the deposit function is for Usuals held on other exchanges. those who have Usuals on other exchanges and want to be part of binance spot trading after usual listing on 19th, they have to transfer them to binance wallet first.
