赌博和投资之间的界线是人造的。最合理的投资具有赌注的定义特征（您损失了所有的钱，希望能使更多的钱}，而最疯狂的猜测具有投资的显着特征{您可能会以兴趣将钱拿回去}。
(The line between gambling and investing is artificial and thin. The soundest investment has the defining trait of a bet {you losing all of your money in hopes of making a bit more}, and the wildest speculation has the salient characteristic of an investment {you might get your money back with interest}.)
