I think the thing most beginners don't understand is that services like this are not in the business of funding beginning traders, this is just their carrot. They are in the business of charging for paper trading account and, above all, they charge for hope. The hope of a beginning trader that they get funded. Statistics of how those services generate profits is impossible to come by and also the profitability of all subscribers in aggregate. I venture a guess that subscribers mostly pay a subscription fee for a pipe dream, also known as lottery ticket.
Well - the way I see it they're providing a service and opportunity which they should be compensated for. Of course they are earning money on failed traders.
I would rather focus my energy on the true snake oil salesmen who are selling courses and lofty promises.
Does E2T or TST do that? If so, I would share your skepticism. As I said - I have not looked into those programs in detail, so I don't know.
