That is something lacking unfortunately.I also hope this happens soon and I am surprised Amazon and other big worldwide marketplaces has not already start accepting it,it would only bring them benefits as it will translate in more people buying things there.

There are small websites,like investments ones,paid to click,traffic exchange,data entry typing sites that accept it or offer to pay with it but unfortunately this is a very low number of businesses online accepting and dealing with cypto in general that also has a very specific user base.
