Clearly, you know nothing about the ED visa. Three years ago, it was basically the same as the DTV with no need to attend classes, just pay the fee. Then, once they decided the ED visa was no longer in their interests, they began multiple rounds of crackdowns.
You also seem to know little about how the bureaucracy works here. ED visa holders already paid quite a lot for just one year, and the related agencies profited from it. Your DTV, on the other hand, is even cheaper, and immigration gains nothing directly from it, so it could easily become the next target of enforcement. Good luck.
