I actually received the video streak bonus early this week. Wonder if I ever receive that again? Right now my account still has enough coins to last for a few more months, so I will wait a little while to see if Boost changes their mind and gives users the ability to earn more coins.
Supposedly, users can potentially earn free service on Helium Mobile if they enable location sharing on their phone. Since Helium just distributes a fixed number of points to those who successfully share their location each day, eventually there will be a time where there are too many subscribers and not enough tokens to cover the monthly payment. Furthermore to get credit for location tracking, the user apparently is required to cover some distance (like a mile???) each day. I suppose that will be okay for those who are in their vehicle all day. Those who work at home would probably not get credit everyday. I am also guessing that enabling location tracking drains the phone battery enough that it is noticeable.
