Bitcoin will become mainstream.

The Bitcoin skeptics don't understand this due to:

1. their biases and lack of financial knowledge

2. being in as strong an echo chamber as Bitcoin proponents

3. rabidly searching for evidence that confirms their view of Bitcoin

4. misunderstanding how good money drives out the bad. Strong currencies like bitcoin overtake weak currencies through speculative attacks and currency crises caused by greedy investors - each pursuing their own self-interest. Not through the careful evaluation of tech journalists and 'mainstream consumers'.
