Obviously it was a mistake to even have that much of my capital in a single trade but I was a newbie so I made a mistake. That had a learning impact on me, I learned that I should not invest that much into a single trade and ever since then I never did more than 5% on a single trade.
You learnt from your mistake and you won't be making that mistake again but some individual never learn from their mistakes and they keep making it regularly. As a new trader, there are some mistakes they just have to happen as we don't have the experience before to prevent the mistakes from happening. I prefer making the mistake when I'm a new trader than making the mistake when I have advanced and now using more money to be trading. Beginners luck are a thing, it doesn't matter if you believe in it or not but it always happens and when you're not careful, you'll think you have gotten good at trading but that isn't the reality.
