If Bitcoin won't die, if it still exists next twenty to thirty years, $2 M will be reached.
I am pretty sure that Bitcoin won't die as it is already the biggest invention and revolution of our century.It is still in the beginning stages being created only in 2009 which means it is only 12 years old and in this 12 years its market share has only grow,a lot of persons now own at least a fraction of it.As such I can assure that Bitcoin will be with us forever,the only way Bitcoin can cease to exist is if the Internet goes down and cease to exist,pretty impossible scenarios if you ask me.May be it will not reach 2 million dollars but one sure thing is by 2025 we will have at least 250.000 dollars for a Bitcoin.
