Didn't know where to post this, 
But anyone involved in the stock market? Like put money in? Did you make good money from it? Is it worth doing? 
Only got loads of questions because I follow this guy on Instagram (Timothy Sykes) and he has seemed to make it look easy to be a millionaire and I'm not stupid I know it must take real hard work to do that and to understand it, just wondering if anyone else has had success with it?
