I have always wondered how people manage to make millions from just youtube channel / instagram account or facebook page.
Pakwheelers come forward and share the information you all are hiding on this thread
They join affiliate programs and sell products for others where they get a cut of profits.
If you have guts to make content on regular basis which people likes and engages with then you can also make good amount of money through these channels.
Any one here knows about bit coin etc etc how to get start
Most of the YouTubers get their profit from ads, views, comments and followers. Like what mentioned earlier as well, affiliate partnership is a really popular way to earn income.
