Hello Crypto Champions:

They do not work for free and this business concept should be quite profitable for them
to fund further development, security measures, and general operational  costs.

COBINHOOD's revenue will come from margin loan interest and ICO underwriting service.
It's recommended that you can check their white paper, ecpecially CH4 and CH6:
https://cobinhood.com/assets/whitepaper/whitepaper_en.pdf

And welcome to join their slack and telegram, lots of people discuss COBINHOOD every day.

Also, many questions answered on URL below here:

Also, keep these points in mind:

1. ICO underwriting - Cobinhood takes 5% or something like that.
2. Margin loans - up to 10x margin loan accumulate interest.
2.5. COB gets 50% of loaned token profit.
3. Listing fees (But, this isn't a continuous stream)

However, the funding itself is allocated in the token distribution. Whatever it says in the
WP as the % to fund the development etc. However, it was said that Cobinhood didn't
necessarily need the cash to launch the project, but the ICO was necessary as part of
Cobinhoods' implementation.
