But in trading you should have good money management and skills to survive under different market conditions.So it is more risky than gambling if you dont know what you are doing.
Yes, in trading we need to learn basics before jumping into it or just buy some good coins and hold it until prices go up. Because if people want to make a profit on a daily basis then they need to be experts but if you want to be an investor then study the coins before purchasing and wait for prices to go up to sell. Trading is a safer way to make money than gambling.
This depends of what type of gambling are you talking about. In sport gambling you always have sure bet and easy wins, in casino games is more experience rather then luck, luck is more for dice games from my experience. Trading is something that can be very profitable with right choices in right time. Outcome in this type of situation can be huge.
