As per their official website registered user with level 1 tier can withdraw upto 10K USD per day but I am not using it anymore for years especially since the hack in 2020.
I just want to give you the warning about their reputation in the recent times is not good so better choose other trading exchanges like Kucoin which still has no KYC trading feature if I am not wrong.
If I remember correctly, this poloniex exchange is owned by Tron co-founder Justin Sun. Recently, this guy is also said to have just acquired the houbi exchange, which is also a leading exchange in the world. I also stopped using it quite a while ago. but I didn't hear about the hack that year because I switched to binance and houbi probably from 2019 to now.
Kucoin is a centralized exchange but it allows trading and withdrawing when you don't want KYC, but you can only withdraw up to 1BTC within 24 hours with a non-KYC account.
Since when sun owned polo? If it was recently then maybe the limit is now $50k per day, not $10k anymore. It might be a form of promotion to attract more users again to use the site since it's said that there's a hack which takes place long time ago and that would have scared many people from using the exchange. It's amazing if sun also acquires houbi. This simply shows that he is rich but I don't think he can buy kuckoin and binance since they are more popular than the two so their selling value must also be huge.
@OP I check the screenies and there's no typo in there. The level two limit also shows $500k but you can try confirming things in their customer support.
