This is the normal state of the market. The price keeps rising and falling. Of course, for beginners it is morally difficult to sustain such a drop in prices, as we observe in 2018. And not only the newcomers succumbed to this pressure.
But I would like to say that the fall can't be eternal, but there are no real prerequisites for the disappearance of crypto currency. That's why you should not panic. Keep calm. If you have the knowledge and skills, then in this market you can earn excellent money. If you don't have certain knowledge and experience, it is better to just wait until the situation in the market begins to change.
