Is it really necessary to take a course before getting into trading?
IMO take a course is mandatory if you never tried trading, why? because if you only have small capital to spend it's better to do some learning before starting to trade you dont want to lose your capital in vain except if you want to feel from trading using demo account until you are confident enough to start trading. Well, we never know if we never try
Whether you have small capital or huge, its advisable to start with small capital if you are new to trading. Everyone think that crypto trading can be easily done and its a shortcut to become rich in quick time interval. But once you jump into it with real money you realise its not a kids play. Everyone must gather knowledge by any means ( whether courses or through expert's) before you start trading in crypto.
