You can earn bitcoin with twitter by participating twitter campaigns in here, bitcointalk service section.
Let me give you a better idea. With fiver.com to earn money from twitter account. Post a gig and wait for some orders. You can earn 5$ per twitter post via fiver.
Search in google "how to post gig in fiver", you'll see all the methods.
