The best idea I can give a new trader is to diversify your money across your multiple coins. If we don't put all our money into one coin than the risk of losing our money is much lower. The chances of losing across 5 different coins at once is very small. If we own multiple coins than our loss in one coin should be offset by the winnings in another. The second advice I think is good to follow is our risk management. We should clarify before buying a coin what our potential losses can be, how much we are willing to let a coin drop in value before we sell. If then put in limit orders at these level, for example 15% below our buy price than we can protect ourselves from a complete loss.
