Ok, so I have to trust you to send you my money for a bet, then you use that money to place the bet in some Asian bookie, and if I win you give me my money back minus your fee. Did I understand correctly?
I would never send my money to strangers via Telegram. Why should I trust you?
one thing is impossible if he will return your money and share the profits, this is a classic fraud, it is better for you to play alone if you lose you know where your money is going,
It is not so. Sometimes you need such service. For example you have some restrictions in your country. But there are lots of such organizations with lots of proves of their stable work. Without "write me in telegram".
As the result, even if the OP not a cheater - the service is ok, the promoting is awful.
