Though he can try to learn trading but he should not throw huge amount of bitcoins. Read and learn is the best thing that a newbie can do and I suggest to learn here in bitcointalk.org but know what posts you should believe and not since information that each member gave is actually correct.
Better not because someone newbie 'in terms of real not rank' must have a weak mentality and what I fear is if they once experienced a loss, they will mentally down and dont want to trade back or even hate crypto currency.
