The government is filled with people who have absolutely no intention of technological development. We can all agree that there are other sectors too that needs attention but these technological limitation is what eventually leads people to shift abroad.
The government for first doesn't have any clue about concurrency and is seen as a threat. They cant build policies for it as it can't be controlled or taxed for the least.
The reason is almost similar why paypal is still not available at Nepal. The NRB bank simply doesn't want outward flow of cash as it can destroy the already weak Nepal's economy. So Nepal's debit and credit card doesn't have international payment support.
Until the younger better administration comes to Nepal, I don't see any hope yet.
