I've done giveaways with one book and a few with two books. The results were the same. About 500 people entered, and about half added the book to their 'want to read' list.
I did not see a rise in sales, and whenever I check back, they all still have it as 'want to read.'
If you can afford giving away 20, I'd say do one or two in every possible country. Then promote like crazy. Could work.
