In the near term bitcoin can not reach the value 20k, but for the future bitcoin will get past the value of 20k. I do not think bitcoin will end, and therefore I believe that bitcoin will be able to reach a value of 20k.
"Near term" and "future" are pretty subjective imho.
Bitcoin was down to 6k and many were crying it'll fall to 3k.
Now it's 9k and every tiny good thing becomes a news. Bitcoin may get pumped faster than many would expect...
People forgot the old pumped days probably. They look very pesimistic and they lose their hope. This is the worst case scenario for bitcoin holders. We know how fast it can be pumped in the future.
