Bitcoin is going to be number one payment gateway in near future.Most of the online payment gateway will accept bitcoin as main payment option.
Well that's what Satoshi's vision was, that bitcoin to be used as a micro-payment scheme, sadly though, it has become just a store of wealth or as a form of investment and currently the whole scaling issue is still up in the air (although fees drop signficantly and the network spammer has stopped).
Maybe in LN would have been implemented, and it brings fees and network congestion to a minimum, then maybe we can see bitcoin being used as mode of payment in the future.
Bitcoin is in its early stage, i think it will take a little more time to achieve its goal for which it has been created. Currently in few area people have the facility to use bitcoin for shopping online or in their local area. Although in some area people are using bitcoin for shopping in their store, but still majority of people do not know anything about bitcoin therefore they first need to get awareness about bitcoin and hope that then they will start taking interest in bitcoin.
