If you buy KalCash and sell 1Euro can give you 1kk.So in your case say if you buy 1000gold KC for 81.30 euro you can make 81kk with some gold kc left so a little more than 81kk for spending 81.30Euro.This is far safer and easier than buying geons, with the benefit of being scamm free and you can make prices as kal economy sees fit...so you can end up making plenty more for your money.
