For me, the banks sucks because they tend to control everything, period!
The bitcoin is fast, secure, decentralized, gives total control and freedom to the people.
Perhaps, you had better experience with traditional banking system way better than bitcoins.

Share with us what you think? thanks

Yeah banks control everything on your money and have tax when you earn. Bitcoin is decentralized, secure and we have control on it. You can earn bitcoin without less tax. In bitcoin you can send and receive anywhere and anytime in the world.
