Mate, bitcoin is so hard to hack unlike other currency around the globe. Actually it is the most protected because even the government cannot have the access for that, unless its developer make it down and security will be bold on to public.
Developers can't do anything. Everyone using Bitcoin is trusting the network rules and it is known. If they want to change a rule, those that will agree with it will form another separate chain.
If you want to change anything in the blockchain, you have to ensure that everyone else will believe it. For it to happen, you need the other nodes to believe you. They will follow their own set of rules. If you try to defy them, they won't trust you and nothing will happen. Bitcoin is backed by math, SHA256 is hard to break and thats why there is a mining reward.
