Why do we really need Bitcoin?
I am a secretive and confidential escapee. I hate keeping money in safes with passwords or depositing money in banks that fear bank bankruptcy. I need bitcoin, will no one have control over my bitcoin account, unlike other electronic money systems, you may be locked account, frozen property. With bitcoin you own the private key, with a separate bitcoin address. No one manages and controls accounts outside of you.
And you?
We need bitcoin because we need investment where we can fully control and fully hold. Likewise, we need decentralize bitcoin because I like financial freedom and privacy. Its been a good idea to have a transcation that is anonymous because governments just want everything to be taxed.
