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?
I really don't see Bitcoin as a need. It is a great opportunity to earn big in the crypto system but it's not a need. Even if Bitcoin suddenly disappeares, we still have a lot of other options to choose from. Bitcoin is simply a medium for financial growth. Personally, I am thankful that Bitcoin exist because it gave people a chance to earn. But tagging it as a need, well, it really isn't.
