I have a couple of tips based on my experience, for those who are struggling somehow due to this boosting feature.
1. Stay online and refresh until you find the best job post to bid.
2. Submit the proposal within 10 minutes of a job posting.
3. Boost to 2nd or 3rd place. So, your proposal will be viewed by the client and the proposal will outboost as well, and boosted connects will be refunded.
That way, you can definitely feel the difference and secure the projects as well.
