Bitcoin will change the mindsets of the people in future, the scenario was same when internet took birth, everyone assumed that it will not survive but today it has become necessity of all, one day bitcoin will also become necessity of the people.
Bitcoin can make revolution and become more valuable and been adopted widely.
But Gold will never be abandoned..
Only if we dramatically change our perceptions about world and life. But this will ultimately lead to system changing and many physical goods will become obsolete an unusable.
This can become future even for bitcoin, not only for Gold.
We already know for such systems like Venus project!
There is more chance for WW3 than for VENUS. Bitcoin is safe for now.
