I agree to some degree, and i don't think that this can be sustainable in the long run, just look at the math and it doesn't take long to figure that out.
I do think that there is a golden opportunity to make a lot of money if your smart. personally i'm of the opinion that i am never seeing my principal again, but the massive returns i can see and actually cash out daily vastly outweigh that initial investment, in a short period of time
