It's amazing how you chose to partner up with castbox, with a lot of numbers of users already using castbox, I know it will be easy for contentbox to achieve goals in the future.
I don't think it is assuranced to be partnered with castbox. I meaned, this project have a lot do before they can achieved their goals. The team behind this project must have to work hard so that they can be able to developed this platform into a good kind and make it a profitable one.
I did not see any proof that they partnered with any company. Are there really some proofs about partnering with castbox. There were ICOs before, they said they were partnered with IBM, Coca Cola ... after the ICO I can not hear from them any more....
