Crypto is more than Bitcoin!!! Lets take the issue of Banking. The system being used (Swift) was made in the 70's. Its way behind all other technology and 6% of all Swift transactions fail! That coupled with the fact that it can take 2-5 days to finalize, 24 hours is possible if it is the same bank. Lets not forget the 3-5% exchange rate. For all this to take place trillions of dollars are held in Nostro/Vostro accounts.
All of these issues could be solved by crypto. Lets use Ripples's XRP for a example as their plan is to try to topple Swift (more likely integrate).
3-5 seconds finalization! No Nostro/Vostro accounts needed. No mistakes!! Can run offline! Transaction cost is less than a cent.
The new iso20022 messaging system starts implementing in Banks from November this year and the whole World banking will be using this system by 2025.
