I don`t think it`s possible to predict when another crisis is going to happen but the fact is that it is going to happen because economy is a cycle where booms and crises differentiate.
Also I think that the reason of this crisis in the future is also unable to predict because every new crisis is nothing familiar with the old ones. People learn from the mistakes from the past and new crisis need new f**k ups. For example: banks learned from 2008 and don`t give out these subprime loans any more.
Knowing the reason of the next crisis is the privilege of a very fev persons who probably are going to make alot of money off it because they know what`s going to happen. I would not bet on anyone from this forum knowing the next reason.
