No problem- even if you would get a downvote, it will not harm your Steem/Pal rewards, as far as i know it, but downvotes are always not good for the community.
If you post some stuff about "investment", steemleo is the right place!
Otherwise steemitfrontend of course, but also palnet of course and maybe "other tribes" in the future of the smt-light market are better places for your content, i like your content!
Best regards!
