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?
Not all people need bitcoin i think to those know about bitcoin they are investing to earn and to get profit. You can invest your money on bitcoin but i think don't put all your money on investment save on the bank also.
