Yeah i would also buy some bitcoin if they go to all time lowest but not sure if i would shift focus to other coins cause they will repeat history. If bitcoin doenst work then the concept of cryptocurrency will be very hard to execute succesfully. especially because the reputation will be ruined.
If bitcoin will reached it's all time lowest then you think bitcoin can even come back to shine again?
For that to happen, a major disaster really happen in bitcoin resulting for a wreckage. Also if that will happen, people will now have doubt about cryptocurrency.
