It seems you're new on steemit, your posts are good but not your comments... no one might have told you yet but it's frowned upon here to ask for upvote-back... and your comment here isn't giving anything of value to the creator of the post.
As newbie your upvote equals $0.00 so asking for someone to upvote you back is unfair... though it seems it can be fair in this case as @rownokhasan is new too and their upvote is likely $0.00....
your comment didn't offer anything. not even something that tells us that you've actually read the post. and not just upvoted and went to someone else.
The number of upvotes anyone can make daily is limited, so they can't just upvote you if you didn't do anything deserving upvote.
I've also seen your latest comments, and most of them are spamming the same message... this way your account probably looks like a bot to most people. You can write comments that makes the poster upvote you willingly. when you engage in conversation rather than asking for upvotes.
