..and ofcourse botcoin wallets are better than banks
Hold your horses. "Better" is a big term so please use it appropriately.
I used both services, banks and bitcoin so I know in myself how I can benefit from using both.
And because Im in the situation of using them both I know their PROS and CONS
No way I can say that bitcoin is much better nor banks is.
The term "better" must have no CONS please keep that in mind.
