I hear this from friends - what if the internet goes down? What about quantum computing? All not realizing that if any or all of these things happen, bitcoin can still survive. Their banks…not so much. 

 I mean, if the internet goes down worldwide, or if an asteroid comes and wipes out the planet…. Then maybe lol 

 Their arguments almost actually rise to that level of absurdity - I can’t buy it because the sun will likely be extinguished in a billion years, so ultimately Bitcoin is destined to fail.
