As everyone has told about it. Bitcoin is cheaper alternative only when you use it in cross border transactions as Western union/ PayPal / credit cards etc. are charging too much. Also the transaction times also are quick if you compare them with these methods. But once it comes to within the border payments there are many sources which are very easy and better and bitcoin then makes no sense as an easy method of transferring money which is why it's not being used.
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.
