First of all it doesn't make sense to me for someone to be staking above his or her earning, because in  that case we can no longer call it gambling but foolishness. Gambling is a game for fun and for entertainment so anything more than this you no longer gambling, but doing something else which is not making sense. Gambling is suppose to be done with the money you can afford to lose, so staking above your earning is just madness if you ask me. And gambling shouldn't be taken as investing, because taking gambling as investing is one of the reason a lot of people staking above their earning while gambling which is not making sense.
