Through the game #Ingress I first heard of this bank. They "sponsored" an item within the game up until recently. When they were first implemented into the game I did some minor research of #MUFG, just out of curiosity. Now that they, possibly, will offer their own cryptocurrency I will be paying "close" attention to Mitsubishi UFJ Financial Group.
