You're nit-picking my words out of context, read what I wrote again.
I wrote what about SWIFT as an example of successful system based on cooperation and you wrote that banks sucks, so no, can't take this system as an example. How is that nit-picking or taking words out of context?
The essence is the banking system at least sucks in some aspects,
No arguing there. Everything sucks in some aspects...
otherwise Bitcoin would not have been attractive, it has to do certain things many times better to mitigate the sunk costs. Unlike Ripple, which basically tries to go to the bank's home court and play by their rules and hope to win, hmmm....
You are arguing out of your own ignorance. Ripple has even more advantages than Bitcoin, if only you take time to actually study how it works, instead of simply dismissing it based on hate that developers will get some money for their hard work...
