I know there are people here at Steemit that post in both languages. Either in the one post, or in two separate posts. I can't recall any names unfortunately. Take a look around and see who else is doing that and if seems to be working for them. Having a coherent strategy for this is a good way to go though. All part of the learning you are currently doing, so you are in good hands.

And well done on the post, and the promotional assistance you could give to another Steemian that you value.
