First of all I have to say to get your posts into trending via a bidbot will cost you at least 50-100 STEEM (depending on the tag). All in all I have to say using bots is ok in my opinion (used them quite a lot a few weeks back but stoped since I saw they are providing mainly negative ROI and as I said it is very expensive to push your posts on the trending page and I do not have the funds to do that).
Yeah on the other hand it is quite simple (theoretically at least) to get your posts to trending and that is to write exceptional content but yeah that is really hard to do if you do not have a talent for it.
