In this scenario, I change the donate button into chance to win, to let people compete with one another. I found out that it is difficult to commit to a reward that is unpredictable.
Typical Interface
33% clicked donate
This is a typical choice that is seen in our normal checkout user flow in digital experiences. The drawback of this technique is that it might be hard to predict how much control the user wants to donate or their donation appetite.
Scenario 2
50.00% clicked donate
This mechanism adds a layer of competitive spirit to the donation mechanism. This ensures more amount of money is being donated, eventhough it might deter participation rates and raise suspicion. This is a rather unfamiliar technique to most users, and could also raise more suspicion.
Strategy

This helps you remove suspicion from your donations.
