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?
Because we need freedom. Bitcoin gives me freedom to invest, gain profit without obligations from the government and freedom to control my money. Bitcoin gives me freedom to be a private investor and private buyer.
