Hi, This is a CJ Helpdesk For all People with doubts.. I will try solving your doubts, Just reply here with what u want to know. If I do not know I will find it and tell you, if still now then sorry So lets start !
nope, not yet but in near future, we might expect it only check and bank transfer [few countries] as yet
Leads are the amount which you get paid when somebody signs up from your ad, they can be free signups or small investment sign ups, they get locked normally on the 10th-13th of the next month you got the earnings ex: if you got $100 on 12th november then they will be locked on 10-13 december
"Locked" means the transactions have been reviewed by the advertiser and are to be paid, but it does not mean they will be paid that month or the following month. If the advertiser fails to pay CJ that month then they are not paid out and it sits in locked until so.
For being a "CJ Helpdesk", this thread has more broken English than I've ever seen at DP (and I've seen quite a lot). Also, there's already a place for people to post questions about CJ - try this link.
