If you know how to interpret things, you can already see where we are headed, and that's a world were there is no way to hide your money from a massive surveillance state. Bitcoin is our only hope at having an alternative economy that it's outside any goverment. The network is already robust enough to survive terrible attacks, nothing has worked against it thus far, not even trying to disrupt it from within, but we need to keep making it better, better obfuscation features as well.
I don't expect anything good from mega corporations like Apple and so on, so Bitcoin is our chance for an open source way out of that Orwellian nightmare.
I think this is doom scenario which will not happen soon. I doubt that paper currency will vanish the next years.There are countries, like mine, where more than 50% in retail shopping is paid with cash. The germans love cash! Even the president of the german Bundesbank Jens Weidmann is against abolishment of cash.
A world with only digital money will not be achieveable that easy.
That however does not mean that Bitcoin won't be successful.Today's currencies lose more and more purchasing power.
Bitcoin is , like Gold, silver, real money and it's purchasing power will rise.
