I am with Kucoin since 2018, last year I moved most of the assets to other exchanges, for none specific reasons. All have/had mostly the same benifits.

But this now, is a bit Disappointing 

 Important Reminder: Upcoming Dormancy Fees on Inactive Non-KYC and KYB Accounts  

To Our Valued Users,

This is a reminder that KuCoin will impose dormancy fees on inactive non-KYC and non-KYB accounts on the 15th of each month. This measure is designed to address the security risks associated with such accounts.

Key Points:
These fees will be charged only to specific non-KYC and non-KYB accounts only. KYC/KYB-completed accounts are exempt.

To avoid these charges, please (i) move your assets out of the non-KYC or non-KYB account or (ii) complete your KYC/KYB verification promptly by the 15th of the month (UTC+8) following receipt of platform notifications.
