Seems everyone really benefited in trading and surely we all profited good to it. As I see trading as the fastest yet risky way to profit rather than mining but before with all of these profit we all loss but then we learned from our experiences and use these to become a greater version of ourselves. Trading isn't for everyone but it can be when we really wanted it.
Yes, trading is always been a beneficial to everyone because coin market value is visible and can be analyse the trend, so that we will know the time to sell and buy that particular coin and besides there are many stories that claims as trading as their main source of financial income and i believe it too.
