For me it's start if yoi already know a lot in that trading system and if you're guided by a professional trader.
First of all, a newbie is called a newbie because he is new. You can't know a lot about the trading system if you're new to it. No one started with a good knowledge about something. Even the stuffs that you've read from some article or some blog post becomes useless/irrelevant when you start doing some actual trading. You'd think that it's quite easy to do because there are different techniques to do trading, but it's really hard.
The chance of you getting guided by a professional trader is quite low. Most of us are alone in the Internet world. We don't have friends and even if we do, what are the odds that one of them is a professional trader. To me, you don't need to be personally guided by anyone at all since most people taught themselves online.
Because even if you have many btc yet you didn't know how to trade nothing will happen.
Sure some thing is going to happen, you're going to lose money.
