I've read that Pokemon is giving out QR codes for Japanese players only, for 1 Golden Bottle Cap on the 14th December for 1,400 yen. Can Americans players do the same and buy Golden or Silver Bottle caps? even better can we get them for free? and how?
Currently, in the U.S. there are no events for the Golden Bottle Caps, unfortunately. The only ways to receive the golden ones are through the Festival Plaza as the number one prize for the Treasure Hunt shop, or Poke Pelago, which is also extremely rare.
