If you don't give it a try, you will never know what you don't know but first you must do it with proper management of funds, hence the reason why you always hear advance traders always advice the new traders to trade with risk management, they should not just jump and started trading by blindly following the trend. In addition to your claim, I don't think trading is a typical thing, if it is everyone will be doing it and there will be no one crying of loss and also telling newbie to stay away from it is very discouraging, its like telling them not to give it a try at all and if they don't they will never understand the market and how trading works.
Good point, you will never know until you try, but then again, you can use all advice as referrence.
Before stepping inside the market, make sure to have a basic understanding and knowledge in terms of money management,
it's your equipment while learning from the wild place of trading.
There is always a learning experienced and the fact that you need to know risk management is for you to handle all the pressure
and adjust when it's needed the most. Your money means your responsibility.
