I believe the OP indirectly wants to know if it is risky for a beginner to trade. But there is not road to riches that there wont be any form of risk and sacrifice. There is always a start from a newbies and soon they will reach there. What should be more important is how will they be able to control their emotions during this growing stage. Of course there will be loss and wins which will cost them to either start over or fall down to some middle part.
First of all, though I understand your reference, trading is no road to riches and a lot of newbies often have this misconception thinking that they can earn a lot of money in no time from this industry which isn't true and people who manage to do that are either lucky or already have very high capital to begin with because the amount of profit you can make from this industry depends on how large your capital is.
Trading and newbies is an unending debate, however, the main discussion about it is that when a newbie gets into trading, their first step should be to acquire enough knowledge about the market so that they don't face problems when they involve finances.
