MLM is not only about doing it in Singapore, this is an
international business.
Example if you are making $5K now, so, if you are still doing some
prospecting, etc, and your downlines grow, you will see the
increase in your income.
As for CPF, you will need to top-up yourself, same for reporting
for Tax. And when you report for tax, you are consider as a
self-employ. If you need more questions on this, just call up the
IRAS and they will be able to help you.
Yes, in some sence cos' they are using hard selling, or make use of
their friendship to 'trick' their friend down for OPP, etc. For me,
I was also once in their shoe, but later change my way of doing it,
and can say that now, evern my family members are also doing MLM,
and very suppport - once they get to understand this
industry.
Hope this helps.
