Pretty good game but needs more upgrades – Jumpy Room - Run and Tap to Jump Review

The point of currency is so that people can spend it on things. The super start is a one time use item. Not really an upgrade. If you want to incentivize people to watch advertisements to get coins, you have to release upgrades such as "increasing invincibility duration" or "increase amount of health". Things like that will encourage people to watch advertisements to get those coins and also encourage people to play the game more.
