Keni! So good to see you here on Hive. Welcome to the revolution ;)

It would seem the best way is to convert SBD to STEEM using the steempeak wallet. Bittrex are trading HIVE-BTC but the wallets not active, so not much good for pulling it out. Lots of people are using Iconomy for selling steem & buying hive:

So, I guess that is the way I will go.
