I have had many of my friends and even members of this forum post thread about how bitcoin was hacked, I want to make a clarification,  bitcoin itself is a decentralized protocol which runs on nodes,  this are group of computers coming together to run this protocol or code at once on their system,  so bitcoin can only be hacked if all the network of computers can be hacked at once which is more or less impossible.  Only centralized company running api can be hacked,  eg exchanges,  gambling site etc.
