Hi @fitri! Welcome on steemit!

You might want to think about posting an introduction post with a proof of identity! Here's why:

Excerpt from one of my post: here

That being said I would encourage people to post proof of their identify if they feel like it. People in general will be a lot more willing to upvote introduction post with identity proof. I know this because I did post an identity proof after @liondani ask me to do so in a reply to my introduction post and this identity proof post was generously rewarded. Also my introduction post also got boosted with so more upvote. I thank you so very much sir @liondani!
