Just be careful to transfer BBP to SouthXChange at this moment. I am already waiting for several hours for my deposit to arrive.
Before you transfer, have a look at last block of wallet. At this moment still stuck at 35185. Also other currencies seems to be behind, not syncing.
(I and others have issued a ticket)
I made a transfer 8h ago without issues. But it's true that last friday it took me a few retries to make another withdrawal from SouthXchange wallet.
