What happens when a coin is suspended?
Trading the coins is disabled
Deposits also get disabled
Sometimes Withdrawals could be disabled but in more cases users are allowed to withdraw the coins to another address or platform
But I think before they suspend this coin they have an announcement right? It seems like there's a specific time of suspension date so that users can withdraw or transfer the coin immediately.
Yes, but not always because there could be unforeseeable scenarios for exchanges like binance. One example would be, whenever SOL goes down lol.
Recently, binance suspended XMR withdrawals without warning, apparently, due to low wallet balance, see:
