Since 3 hours I am not able to chat with anyone . What do girls see in guys and they reply them?

I think the better way is Leave message in a complete sentence what you thought about her (Compliment) first. Do Not just leave a message "hey, wanna chat" or "hi" this message is not a good beginning of greeting( may not lead into conversation). If you really like someone Start with questions (some special things you want to know about her). And if she didn't respond which means she doesn't interested because you are not attractive to her or may be not her type when she overviews your profile.

Just say "Hiiiiii".

You are looking for free sex then most on this site are going to ignore you.
