(5) How long it will take to see the bitcoin price skyrocket to $1M
but i'm sure if more people want bitcoin, the bitcoin price will reach $ 1M faster.
i really hope that happens in the next few months.
we can predict but it cannot be sure that bitcoin can be replaced as global currency. More no of countries started accepting and using digital currencies but there are few countries in which Bitcoin /digital currency is still banned, for digital currency there is no authoritative control so this bitcoin may or may not become global currency.
