Not because you have issues in 444sports and Betcoin.ag meaning that 99% of bookmakers re scammers , you should dig a little deep more because putting this statements,
because there are majority of Bookmakers here in forum advertising that legit and trustworthy , and even Betcoin.ag that you have been claiming
is one trusted site so i doubt your opinion .
but anyway since you are newbie i don't think that partnership will come to your end that easy because there is a some questions in your motive why there are claims
of being scam victim and then wanting to have partner to make look your personality a good and a victim but in the end you will be the one who will scam others(I'm not saying that your are scammer but there is a other side of your stories that harder to believe in)
I can agree that there are several reputable bookmakers here in the forum.
They can handle large bets and withdrawals as well.
Don't know the ulterior motive of the OP, but yes, since he is a newbie, I don't think someone will get in touch with him with his proposal.
If he is sincere with his proposal, he needs to look out for his potential partner not on this forum but within his circle and pitch his proposal.
