I think I've heard this story before, most newbies don't do their research properly before trading...you can't just decide to go all in from signals you got from others that you are not even sure of...most people are just too desperate to make money quick that's why they try to rush the market and Skip the process of learning...The market doesn't care whether you are a newbie, if you get on the wrong side as a result of ignorance you will end up losing money.
Greediness is part of what normally kill newbies in trading. They will always want to make it big without having the fundamental knowledge that could help them succeed. Even if they have the fundamental knowledge about trading but as beginner, they are not expected to use such huge amount in trading.
