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?
Well bitcoin is not a basic necessity that we really need. I am also a person who is not comfortable keeping money in safe boxes cause it would only make it stagnant and so with banks because of minimal interest rates. I would rather invest it on somewhere else and bitcoin and cryptocurrencies are a good option.
