If you qualify 21% level for the first time, you are called Silver Pin. If 21% is done for 3 months, you are awarded Gold Pin.
Let us assume, you do nothing but sponsored only one person .He builds a profitable business and done 21% level. He will be awarded silver pin by Amway. You are not Silver, but you will be entitled to receive 21% differential commission from the business done by you apart from your silver team.
You will also awarded silver pin once you started sponsoring others and build a side volume of 4000 PV apart from your silver team.
