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 it because it offers another option as a currency for people to use and an investment medium for people to venture in. In this day and age where everything is done via online, it's better to have more options that people can choose from in doing transactions on the business side of things. That way, it can give us the capacity to venture in the trade and exchange market however we want to even in our personal capacity as individuals.
