There comes a time when it all ends up with this: You have to take a decision on where you are at, and you can only have 2 options
1) You get on Bitcoin now and acknowledge his potential then reap the benefits later
2) You keep being a skeptic/hater and become a laughin stock later, just like the "the world doesn't need computers" guys.
I remember the head of IBM said the world only needs 10(?) computers.
We need bitcoin and other crypto currencies to succeed to enrich our lives and liberate us from perpetual fiat inflation.
