What are your 2 most important technical points of Bitcoin, where you would say "it's really important for Bitcoin and people should know it". Important would also mean for Bitcoin from a hacking-resistant point and what is making Bitcoin superior against competing Altcoins?
1) Bitcoin is made for normal people, not for criminals, not for drug dealers, not for hackers. Bitcoin does not require any special computer knowledge. If you know how to use computer/mobile phone, you may use Bitcoin.
2) There are no people "responsible" for Bitcoin, there is no "helpdesk" - all is public. There is no single company or bank, which could be hacked and be forced to shut down the whole system.
