In happens in every kind of investment. That is not a new thing. The people with nerves of steel and a plan beforehand are the ones who will most of the time win, if they did the right assessment during the planning.
It all comes down to who have the most financial intelligence. It's very simple in fact, yet people don't understand it.
It's not some preying on others. It's people lacking preparation and enough mentioned intelligence to gather enough consistent profits. Especially in Bitcoin, panic selling is almost a sin.
For investments outside of crypto the only exception would be a big crisis in determined country.
And not listening to the opinions circling around on the news about all of the doom and gloom. Forming judgements of your own and having the courage to stick by them, even when everyone else is shouting the opposite. That's why people should spend more time learning how to read charts instead of listening to other people's opinions.
Human nature is to play the victim in order to save the ego. It's much easier to say that it's because of something or someone else than admitting weakness or wrongdoing.
