This is a high volatility market? People don't understand what it means, it means the risk is very high, it can break you more than it can make you, it's takes luck and wisdom, consistency and lesson and teachings learned about trading, coupled with discipline the individual uses to take profit.
Bitcoin isn't as highly volatile as other altcoins, but yeah it is some what volatile. There are people out there taking the advantage of this volatility and making huge profits. But one small mistake and you could lose everything you had, that is something I won't deny. If you act smart and not invest on those shit coins, chances are you will make loses, but you won't lose "everything".

Best is to learn the exact process or strategy, and trade for yourself, than give your money to someone to trade for you in a very high volatile market
No, you should never give anyone your money to trade on behalf of you. They won't care if they make any loss since it is not their money.
