I consider that something is impossible if it never happened before. In 2017 Bitcoin went from 1000 $ on 1st January to 19 000 $ on 17th December. 19 times. So, yes, it is possible, it happened before.

Some people are acting similar to meteorologists in my country, if it rains today, they predict that it will also rain tomorrow. And they are usually wrong. World just doesn't work that way.
