Well I can't possibly say that Bitcoin can reach $1m because considering the current value I think bitcoin still have a very Long way to go because it have not even gotten to the middle though there is every possibility that bitcoin will touch $1m but I don't see this happening in the next 5 to 6 years regardless the volatile nature of bitcoin i will still find it hard to believe that bitcoin will touch $1m before the next 5 to 6 years but I won't be surprise  to see this happening because alot of people have chosen to go into bitcoin investment lately while others are still preparing to get started this are the things that will trigger the price to keep moving.
