If you want to buy, any currency will be good, steem or sbd. When you don't use the banner, you pay 0.15, if you resteem a post from the group. If you don't want to resteem, you pay 0.3. So you can choose different options for different posts. You pay only for the post that you like to pay for, or in another way, you pay only if you want to use our service for a certain post.

You can say that we are building now a whale by gathering minnows all together to make the change in steemit. ☺
