Hey there @iramarsela! Welcome to Steemit. From our experience, the best way to get followers and upvotes is to engage with the community. One way you can do that is by writing thoughtful comments after reading another user's post. It really helps build relationships.
I think you should consider writing a unique comment on each post you read rather than copy/pasting the same comment asking for upvotes. It's spammy and doesn't come across as genuine.
Hope this helps! :)
