I think having a trading comes a lot of advice from the master, a book about the many outstanding trading and clues we can get free on the internet.
Trading is easier and also way more profitable, its less more risky than gambling and also more profitable most of the times.
i don't think so because for now, few people that could make profit in trading because the situation now is unpredictable and we should be careful to do trade. but for normal condition, i think trading is better than gambling as if we are getting loss in trading, then we can hope that someday the price will be rising more than the price we bought the coins so we can make profit. but in gambling, once we are loss, then it need more money to reach what we've loss.
