I agree with this suggestion, but there has to be a donating system where the person is clearly aware of what they are donating.
For example, on Hypixel people will tell others to tips themselves(for something like free coins although the person that said that is only trying to get their coins)They could tip other people all of their coins with just one click without knowing what happened. (This happened to me on Hypixel)
Make it clear that the player is donating money to another player and not getting anything in return.
Also, I believe there should be a 1000 donation coin limit
