Ugh no of course.. After you submit a post, there's a period of 24 hours to generate any income and you automatically get paid the amount that you made from that post onto your steemit account, and then you can transfer to bitcoins or any cryptocurrency.

Let's say I publish an article on 13/11/2016 in 8:00PM
The earning availability from that post will end on 14/11/2016 8:00PM and you will get paid in steem dollars automatically what you made from that post.
