To be honestly I didn’t even know they had aggregated pools, but I will 100% look into it. Where did you find the aggregared swao on the main exchange page?

We operate with two pools of addresses for BTC deposits and transfers - mixed and aggregated. In a mixed pool all received and sent transactions are mixed together and there is no way to discover how many people are behind certain addresses and traceability is extremely difficult, which is very good for privacy but bad for risk scoring. In the aggregated pool all transactions we receive from users are collected on a known single address which is also used to send payments, what will clearly show you have interacted with our exchange and it’s good for interacting with other major exchanges to avoid any risks of frozen funds.

These are cons and pros of each pool:

Aggregated pool (bc1qu2dq8w8lv8v3l7lr2c5tvx3yltv22r3nhkx7w0)

Pros:

No risks of being frozen at major exchanges due to low risk score given by chain analysis platform

Chain analysis platforms will know you have interacted with an exchange and won’t increase a risk score of your sending addresses

Can be useful when someone asks you for a source of funds

Cons:

Reduced privacy

I had X,XXX eaten by a swap before so now I only use BXYZ to XMR. I wish I knew about this for some trades. Wonder if it’s limited to pseudononymous currencies. wish I knew where to find it and more info.

All options I see are flat rate and dynamic rate. Maybe you have to contact them about it.
