For me, the banks for 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

Bitcoin is decentralized, and fair. This is the exact opposite of what banks are doing, which is essentially the exact opposite.
Central banks around the world have the ability to create extra currency out of thin air without the consent of the citizens. Bitcoin is backed by hard code, and there is a limit on the amount of coins that can ever exist.
This is why i'd choose btc over fiat(issued by a central bank) any day of the week.
