No, it isn't like a gamble, there is a difference between trading and gambling. If you only want to gamble on your coin, you don't need to master your coins. Learning everything about the chart patterns, the fundamentals, current issues, or a proper strategy to use, is a part of trading activity regularly. This makes the opportunity to earn profits higher, so we don't gamble whether gain or lose. That's why the better understanding of this, the safer it is to trade. This is something we cannot find out in gambling.
