Could bitcoin disrupt the remittance industry and become the go to solution for cross border payments?
I don't think so.
In as much as Bitcoin has better financial benefits, and offers a better secure transaction, it still won't overtake what remittance has put in place due to the reasons I explained below.
Bitcoin will coexist with everything that already is there.
It's an alternative, not a way to destroy everything else and inject itself into the system to refurbish it.
