Trading can be very risky if one is not experienced or has enough knowledge about it. As you are a newbie, I wouldn't advise you to go into trading without adequate preparations.
Firstly, you need to gather all information you can find concerning trading with cryptocurrencies. Then, you need to study them to understand the basis of trading so as not to run at a loss.
You can, however, find all information you need here on bitcointalk forum.
A newbie can invest in some cryptocurrencies, but he should start with the minimum (not over $500). Additionally, he should educate himself about the market and crypto a lot.
