There are many newbies who entered into trading industry here in Bitcoin or altcoins, were in the end most of them(newbies) are failed in to do so, due to majority of them are just come what may only. Entering in trading industry without full knowledge of trading for sure they will fail in the end. So, I would suggest you to study first about it feed yourself in the first place about what you are choosing it to do so.
My personal view is that we should encourage the newbie to start trading despite of discouraging them not to trade, in fact in very beginning they should start trading by investing a very small amount of money, and when they get some good experience then they should increase their investment, in fact first they need to get some good knowledge and experience about trading, because trading is a vast field and one can only get experience if he is spending some good time in trading.
