Bitcoin is an exponential innovation.. In 1989 if you were to send an email - you would compile a version of the Unix mail program using a C compiler and Unix command line skills. You needed to set it up on the command line, type out the email, and then that typed email was transmitted across the great internet in an astonishing THREE days.. 20 years later, an old mother was able to replicate that experience with a swipe of her finger on her iPAD.

Bitcoin is in the same stage as internet was in 1992 - 1994.

I was just reading about an old news from 2011 where  RSA (security company) said that its SecuID authentication tokens had been hacked. Ofcourse back then we had hardware device for receiving authentication codes, and these days the authentication codes comes on the mobile phone - SMS or phone call or GoogleAuth and other apps..


But the above news from 2011 got me thinking if even Google Auth app for 2FA is safe ? How is 2FA vulnerable to hackers ? Thoughts?
