My cousin sent another transaction this time, same Source and same destination wallet, it got blocked, he verified the kyc link sent to him and guess what? It got refunded in an hour!
If i understand you correctly, your cousin sent XRP from the same gambling platform and bookmaker into Changenow, just as you did? How much worth of XRP did he send and did you do this for testing purpose only?
Their scam is selective , they choose big amounts
Yes that is what they do, there are still quite a lot of people that use this exchange successfully, but i think it is for small amounts only, but big amounts are likely to be seized and then they try to frustrate the person. One last question, your cousins transaction was not processed, but the money was returned to his deposit address, right?
