Both Hodling and trading carry risks. We just anticipate the price movement which might get wrong due to any of the reasons.
But, despite how risky it was, still we have a way to minimize losses. Like, if we do trading, we don't have to rely on luck. Perhaps, doing it better and enhancing our knowledge and skill helps a lot more than speculating the market.
We have to be clear that trading is really different from gambling. Gambling was just 50/50 chances of winning, unlike trading which we can increase it by working it hard and pushing ourselves to the highest level.
