Trading is maybe very unpredictable but its also very profitable so I think its still worth trying it out and you will see that its risky but profitable.
I assume you're talking purely about Bitcoin right now, so yes, everyone has to start somewhere, but the main point of importance is that you don't keep pushing yourself when you're simply not in for it. If you realize that trading isn't the right thing for you, then it takes courage to admit that and to skip trading entirely. However, some people constantly force themselves to become better in trading while they keep making the same rookie mistakes. And in some cases it's year after year, after year. But hey, without these people screwing up with trading, smart traders wouldn't be making that much profits.
