If you say mismanagement of money, that is like an understatement to me. This is topically lack of trust because if people don’t trust you, they will never give you their money in order to do something, but you end up using the money to gamble just because you are greedy and lack trust. Although some might be in such situations not just because they are gamblers addicts, they might see a hope of winning the gamble, which will arouse their interest in spending more money so that they can get higher profits. forgetting that gambling is a 50/50 scheme where either you lose or you win, but too much hope can lead you to such issues. 
 
I know a story about someone who tried gambling with the money for a contribution but succeeded. To me, there is no point in whether you succeed or not. All this is not supposed to happen because if people trust you and give you their money, I don’t see why you will have that in mind that you will use their trust on a risk that just defines you as more selfish than holding people's trust, which is not supposed to be that way.
