chain group requires any group listed to deposit the amount to them.

IE dragon Foundation has 50k in chain.group's account to EVEN LIST on their site.

your investment if dragon does not return on the agreed amount, chain group will cover the loss from the escrowed amount.
this has never happened, but it is there.

you can call the number on the site and ask them, its in the Faq section, it is also explained here on my yt video
