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?
Exactly this. I would like to put power in the hands of the people. I am fed with all these banks, payments operators, companies which are processing payments for payments operators etc. etc.
It seems that my money is like circling around and to reach its destination around ~5 companies need to take care of it along the way. That is why the direct p2p system is far, far better.
