Lets see if I got all this right. You registered account under your friend's referral link, your friend has many accounts, you won something and then you sent funds to your friend's wallet. Your friend deposited those funds to one of his 1xbit accounts and 1xbit blocked you. Seems you know a lot about your friend's activities.
Do you have transaction ID? That one where you sent funds to wallet of your friend?
Yes i have transaction ID and im in contact everyday with my friend we talk alot about casinos and bookmakers
I can proof everything its no problem for me
