These are the points I have accumulated over the past 5 years without ever exchanging them.
To be honest, only elderly people who changed their business from waste paper collector to empty bottle collector are the ones who put empty bottles into the nephron.
It is a daily routine for professional collectors to secretly take out empty bottles discarded by people from local recycling bins and sit in front of the collector for tens of minutes to put them in.
Because of this problem, Nephron later set a limit of 50 per account (phone number) per day.
Older professional collectors use several phone numbers. (One person logs in to both nephrons at the same time and injects both)
To be honest, unless you become a professional waste collector, Nephron and online waste paper collection are just like dust.
If you do this often, a person’s mind will become narrow.
