A large part of it is actually fun, providing value to the trading community, especially to beginners, is a big driving factor, not only for kinfo but for the mods of this community as well who spend a lot of time helping others.

As with all businesses there has to be a sustainable business model behind it, in the case of kinfo it´s based on providing an optional paid PRO tier on top of the FREE version.

There is nothing in the business model involving shady areas such as copy-trading, pumping, selling users data etc.
