For me, I think 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

My vote is for bitcoin I do not need to go directly to the bank to pass the requirements and fill up the application form. I do not need to disclose information about myself. Plus if you put your money on bitcoin it will grow relatively. Unlike banks the highest interest per year would be 3% which is really low compared to bitcoin.
