When you say "most people feel this way", what part of the world are you referring to?
What downsides are you referring to? please elaborate. There are plenty of trade offs in all things, but if you're more specific, I can better address the concern.
In your last paragraph, are you referring to another "coin" aside from bitcoin? It reads like you are but you're unspecific. Also, the ad hominem attack doesn't help convince anyone. Give me real arguments. What coin are we waiting for network effect to increase? The market has been pretty clear on what it values the most at the moment.
