@anarcho-andrei, have you looked at the Bitcoin site? They offer merchant accounts. Just add:
/merchant-solutions
to their home page. This could be one of the several temporary bridges for you.
BTW, seeing your alias, you might want to check out my profile and my introduce yourself post.
Upon a bit of thinking, you can contact Ned Scott (@certainassets, Steemit: @ned) our CEO and inquire if he and his team are or will consider offering merchant account services for Steem.
