I would choose trading over gambling without any doubt, by some means I still have control over the outcome of my trading compare to gambling. But of course, trading requires research and knowledge, unlike gambling that does not require that much expertise and somehow only rely on pure luck.
Of course, both are risky, there is no certainty in gambling because you cannot predict the outcome. The same as in trading, markets are volatile and changes overtime but with right knowledge and experience there's a high possibility that you will succeed. So, I would say that gambling is more riskier than trading.
Concentrating time on trading will be better than playing gambling because trading will give you more opportunities to make a profit. And if you continue to study trading analysis, it will surely be useful in finding coins to trade. The better your analytical skills, the greater your chances of making a profit. And you can also set aside a small amount of money for other things that can benefit you in the future so you can make a profit too. But it's different if you focus on gambling, where gambling is not a place to profit.
Actually trading is not that easy as it sounds, to make money through trading you need to learn and build trading skills. On the other hand gambling is just game meant for entertainment wherein a player with out any skills can win money with only luck. With trading you do need some luck but skills plays a major role in your earning. Day trading is way to make money through trading everyday and most pro traders are doing day trading.
I completely agree on this one. Trading can actually be a full-time career opportunity and I know some people who generate huge amount of income. On the other hand, I don't really see gambling as something that we should rely on to earn a living. For fun and entertainment, yes it can be, but being dependent to it to earn a living is a big no.
