Invesments And Online Trading

I can't say as I come from a family that are into investing or Stock Trading or any of that sort of thing. I come from the sort of family that 'get by' or make ends meet. So there was rarely any money left over to consider investing.
My generation however are a bit more financially secure and do have a bit more money to 'play with'. If that is the right sort of terminology. Some of my relations have invested money in an Online Broker firm and sometimes the conversations they have at family gatherings are nothing but gobblygook to me. For some of them it is a bit of a 'buzz' using money that they don't need for anything else and for others they are looking for somewhere to invest their money wisely to go towards things like pensions or their kids future education. I can safely say that most of the investments I have made over the years are investments of the emotional type rather than the financial type.
My cousins tell me though that Online Trading is one of the most popular ways to use any spare cash or to invest savings. They often try to give me advice on best possible options on how to use my money 'more wisely'. I am lucky to have them, for advice.
