Are you going into trading for the money or for the knowledge?
Don't be too faster than your shadow, trading is not meant for the lazy. Don't think immediately you get into trading, you'll making money, cos time is necessarily important to gain mastery. The great traders who are making great profits from trading had already sow the seed and now reaping their harvest so let's be patient. Don't rush cos slow and steady wins the race..."Power of consistency" with brain not just working blindly.
I think you are right, but not everyone wants to be a pro in trading. Not everyone even want to learn. Some people will always want to earn even without learning much. They can achieve this when trading by proxy. They can be trading with reliable signals (if there is any) or by copying trading.
So, in which ever method, the most important is risk management. Being aware of the reality of the market. Market volatility can shock anyone, even pros.
