Do you often watch videos like this to improve your skills in playing BlackJack or other card games? Or do you feel so confident in your abilities that you don't need such video courses?
As someone who often plays blackjack for fun and for gambling, I do think that reading and watching videos may help someone learn the basics and the foundation of the game. In addition, this may also help them better understand the dynamics and learn new techniques in order to at least mitigate the risks of betting. However, I also do think that such is unnecessary especially if you are a person who wants to gamble quickly without wasting any time.
These courses are definitely great and they help people understand better the basics of the game. If you have the extra time to watch the videos and learn the courses, then feel free to do so. But if you are someone who just wants to gamble out of sheer curiosity, luck, and/or entertainment, then it's better to skip it.
Without a doubt those that just want to get some fast entertainment are not going to be very happy about dedicating time to study a gambling game when what they want to do is to relax.
But for those that truly love blackjack this is going to be a great way to familiarize themselves with the game and the optimal way to play it, after all if you follow the basic strategy then the house edge drops considerably and you can play for longer the game that you love, which is not a small accomplishment at all.
In every activity you want to dedicate your time with, it means, you are interested with it. So if you want fun without wasting too much effort, then, this is not for you. You can always play on casino classics where you don't need to think about. But if you want a mastery of specific game like this blackjack, all the resources that are available, you will want to read and learn. It means, you can allot your time for this kind of activity and you are willing to know more than the basics of this game.
