I downloaded the BitSharesX client, created an account, and kindly received 30 BTSX for doing so.

I've spent a few hours reading about BitShares and I'm impressed!

I'm also confused. I bought PTS on Cryptsy and want to withdraw it. The BitsharesX client appears to be an exchange, but from what I've seen it only handles BTSX. So I downloaded the BitShares-PTS client and am waiting for the sync. But how then do I exchange PTS for BTSX?

Is this 30 BTSX from a promotion? How do I get it?
