But the only thing you need to know is don't start trading until your account is fully verified even though they say you can trade without verifying small amount but based on my experience they may stop your withdrawals and ask you to verify your account any time. So instead of facing that situation you better first verify your account and start your trading.
Also, you should know by now that we shouldn't keep our coins in any exchange for a long time. If you don't have plans to sell your coins immediately then better withdraw those coins to your personal wallets.
Also about holding coins in exchanges for long wasn't advisable because exchanges are target of hackers so to prevent being a victim better keep it safe in storages or wallets than leaving in exchanges
