I have one question regarding payment I dont understand.

Day before yesterday morning I sent 520k BBP from C-cex onto address BNxpNcfZDzGknyqguVh2anPKae2jrAfGxH (TXID is d72cb76f612698b96c3057b5b1f553c17d93f8eb07b85664cebd973549de2140)

When I take a look via BBP explorer on the main wallet address BQGcjqjbx89DYqtHc9MpubeEBnbb9FPyfg (address for the same wallet) I don't see +520k. I just see there some + 170968, rest of the transaction goes to another address.

Result: the final balance checked via BBP explorer on the main address BQGcjqjbx89DYqtHc9MpubeEBnbb9FPyfg (2863625) doesn't match now with the balance in the wallet (more than 3.2 mil.)

Question: how it works when I have more addresses for one wallet? And how can I check the final balance via BBP explorer?

I will appreciate any answer. Thank you.
