First, make sure that you have an activated TRX wallet by sending 1 trx to your trx receiving address. After you click your sponsor's referral link, click the join button after you copy your trx wallet receiving address. Make sure you see your sponsor's name on the registration form. (If you do not see it, just click their referral link again.) When you paste your trx address make sure there are no spaces before or after the address. Once you completed filling out the registration form, check your email and click the verification link inside the email. If not in your inbox, check your spam folder. (please use a gmail email to assist with deliverability. Hotmail, AOL, Yahoo, and other email carriers have poor delivery issues!)
Your Lifetime membership to be in the money network is only a one time fee of 50trx. Which is about $5 at current Trx rates. Value will change as rates change but will remain entry at 50trx.
