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.
In my opinion, trading is best option because through trading we shall become expert. In future, people will show trust on us and they will give us money to invest and make 50-50 percent profit. In this way, we can invest other money and can get a huge profit because every person investment plans are different. Some people can invest 100000$ but they don't have skills, in this way we can help these persons and we can make a huge profit. If we have skills, we can invest own money and can get good return on investment. But in case of gambling this is not possible, there is no learning, no skills and no experience. One day you can win and will be king and next day you will be on road, if you lose.
