Sincerely, this is like the kettle calling the pot black, what prove do you have that you are not actually the scammer?
I've never betted on table tennis before, but I believe there is always a first time to everything, I will reach out you on telegram and give you a test, I guess i am good as long as I wont have to send a dime to you until I win,
But you should have mentioned what your cut or percentage is after each winning so that those contacting you will have that at the back of their minds in other not to prolong chat in negotiation of what percentage is fair for you and the bettor - this is just my suggestion anyways.
