Well said. I think everyone knows that they shouldnt invest the money that they cant afford to loose. And they shouldnt invest all of their money because this is an unnecessary risk. Actually these things are very simple, basic. Everyone should know it.
Absolutely right and it should do so because if anyone take risk more than his afford loss amount then that person may suffer a lot in the long run. So, they should avoid any type of investment for which if the loss cant afford for rest of the life.
