Why do people lose money in crypto? the number one reason is panic, they tend to be controlled by emotion, for newbies never ever just bought something you really know nothing about, that's one of the rule, research is needed, your money is important so don't waste it with wrong decisions, if you decided to what coin to buy, don't sell with small movement crypto is volatile, make some target for losses and earning.
I think if they are traders who have been familiar with crypto for a long time, they will not panic when they see the market being dumped. Because we have learned from the experience of previous years. Maybe new traders, they need special guidance in the context of trading. But I often lose because of the basic needs that must be met. Because I do not have special capital to trade.
