Newbie loss huge amount of Money coz of they haven’t actual trading knowledge. They buy token without analysis they just follow hype. And they haven’t patience for holding. That's why they loss huge
You have said the main few point why actually the make huge amount of losses .They don't have proper knowledge behind trading and they start trading when they just saw hoe the btc and most of the top coin has huge amount of gain over the year .They enter on the market when the see their traded coin going to the opposite direction where they were really not expecting there become panicked after that and sell their all asset and make a huge loss .So i wanna suggest them to do study from different source like youtube ,blog from professional trader and hope gradually the can get a good knowledge on trading .Then start trading with low amount to know everything about trading and make their confidence high after that he/she have his/her own experience on that and easy can speculate and enter on the trading .Hope he/she can get profit after that and can avoid his loss .
