Welcome, Nida! The best way to learn how STEEMIT works is to keep working to understand. It is very confusing when first starting to know what you need to learn first. The more you post and comment, the faster you will learn. I think it is better to feel comfortable here before worrying about bots and the automated services. Remember that someone is making money from them and the promised rewards may not apply to a newcomer. Most of us are minnows!. Post something every day and reply to comments. Add interesting people to your FOLLOW list and you will see what they post on your feed.
