You should not think of going into trading if you hate to lose money. I have read some comments both here and on social media on how much has made and lose. Trading is all about losing and making money, if you are afraid of one then avoid it completely.
I have been trading stock and forex for more than 9 years now and of a truth it takes fearless mind to do so. You want to succeed in trade then you need to remove fear out of the way. Fear make you to lose money and opportunity.
I agree with you, but in as much as taking risk is a fundamental concept of trading, not every risk is worth taking and that's why every trade expert will advice you to take calculated risk when trying to go into cryptocurrency trading or any volatile market by using a spare cash or any amount you can afford to lose because the market can always go against you. Trying out risk management techniques such as stop-loss and T.A can go a long way in helping minimize risk
