It is impossible to tell how much he referral is worth since it is dependent upon the number of people involved. As more people sign up through the referral pool, the more people who are getting tokens. Hence, it will vary as time goes by.
There is no limit to the number of people referred. Referrals are direct meaning only people who use your code are you paid upon...the payment is for 12 months from the time they verify...then you no longer get the referral on that person.
The tokens cannot be moved out yet, hopefully in the next week or so that will happen. They are doing the final security checks on it.
Tokens are traded on Southxchange. One can set up an account there, and move Manna into whatever cryptocurrency is desired. From there, one can do whatever he or she wants in terms of converting that to fiat.
Thank you so much. I am truly grateful to the answers that you gave me. I really appreciates. You are truly the master...lol. Thanks
