Absolutely correct Bitcoin is a good option when you are transferring money Globally. The transaction can be made faster if you pay more fees which is still cheaper than the fees paid when doing a transaction with fiat currency. It will take a lot of time for it to become a global payment processor. Bitcoin came into existence in 2009 and it is too early for it to become a payment processor. Bitcoin lightning network is still being under work and in the furture it might help Bitcoin to come on that list.
I am not sure whether Bitcoin would become part of that list in the future but I am confident Bitcoin lightning network would become a major player as an instant payment system within the border and outside it. It is still early as it is still being worked on. I still would like to see a blockchain that doesn't charge a fee for transactions within or outside.
