Bitcoin's founder, Satoshi Nakamoto, was very active with the community in the early days of Bitcoin.
He shared his wisdom, patiently explained all ins and outs of the protocol and even cracked jokes here and there.
Satoshi silently left his project years ago but his legacy will remain with us forever.
The root problem with conventional currency is all the trust that's required to make it work. The central bank must be trusted not to debase the currency, but the history of fiat currencies is full of breaches of that trust. Banks must be trusted to hold our money and transfer it electronically, but they lend it out in waves of credit bubbles with barely a fraction in reserve. We have to trust them with our privacy, trust them not to let identity thieves drain our accounts.
