If you mean manage is to do trading. You should do something that provides a high security system such as vip (must do the account verification) every your transaction will be able to get information before thru text. Beside BTC or ETH, try altcoin occasionally.
If someone is newbie, then I think we must not advice him for the trading, or atleast we can warn him to do the trading involving small quantity of the bitcoin, because if the beginner will lose something big, he will get dishearted and may leave this business, and in actual this will be the overall loss on all of the bitcoin family. No trading is also no recommended. Trade involving small business are the key to grow from newbie to a professional.
