OP maybe hide some informations and considered as confidential because its his own strategy and don’t want to get exposed. Considering the time and the discipline of OP, he might telling the truth on this successful story. There’s a very few gamblers who monitor their activities online, I can say they are discipline gambler and that why they succeeded. This might be too good to be true but let’s give OP the benefit of the doubt, we have nothing lose anyway.
If OP does not want to disclose the fact then there is no reason to post it. But I do not think that is the fact. I think OP just wanted to say something which is something like a big gossip, nothing else. It cant be a way (logistic way) to make such a amount. There is no way to earn on any gambling method even in any business.
