Even he is betting on bet365 I'm sure if you give the money to him without betting he will run and make 100% profit. Since he is newbie it's hard to trust this kind of words unless if he is one of the trusted member here on the forum. And it's an obvious scam because he wants to bet no less than 0.1 which means big money. So not worth it to risk your money for his service which we do not know if he is real or not.
There is always a chance you said could be true. Anyway, even if OP is a trusted user on here, i believe you won't lend your money since he could be lose too and you lost your money.
