What's stopping you from :
- signing up on an exchange
- depositing your steem on the exchange
- exchanging it to bitcoin/bitshares/ether
- sending it (withdrawing it) to your Steem Power wallet via the "Buy Steem Power" button from the top-right menu?
What's stopping you from :
I can't transfer anything out
Sorry, I thought your steem wallet was outside of steemit.com. Anyhow, seems transfers have resumed now.
