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?
Aside from the fact that bitcoin has the most expensive value among all the other currency, we should also take consideration of the fact that bitcoin is the very first cryptocurrency ever made and that's not all yet, it was able to surpass all the obstacles and become successful that's why it became a global hit which helped it a lot on making its value grow more.
