I' ll take bitcoin as an example.
Is it mandatory that the value of all bitcoins is equal to the value of the world economy?
Can this value be archived before all the bitcoins are mined?
When I buy bitcoin someone will take my dollars.
So how can we technically replace all dollars with the bitcoins?
In the end will there always be someone with only dollars in their pockets or am i wrong?
So what me and some people think bitcoin will be the global currency, it won't beat dollar and be more popular but it will be like a dollar, so we could just pay or do some things with dollar and bitcoin at the same time.
