Thanks bigbagofbricks..... I appreciate your opinion.
but if you simply browse google with the keyword "yop"
you will find-- yopmail, yop chat, yop- android apps, yopservices, yop tax credits, yop.land, yop- Youth Opportunities Program...... and so on.........
none of them are about yogurt!!!
so why not yoppay as a financial brand? As you can see it sounds (pronounced) like "you pay and yippee!!" So we can say Yoppay = pay with joy!! :D
