i dont want to let them know where come my money from because iam funding different accounts from same bitcoin wallet. And bookmakers dont like when somebody have there multiple accounts. thats reason.
bookmakers... are you depositing for gamble purposes?anyway, if your intention is to send from unconnected different accounts then coin mixing is the only way for you
they could know accounts used mixer but can't proof those accounts are connected
try ChipMixer
might suit your needs
