You need to test it first so I wish NYM adds daily plans.
In 24 days my monthly Mullvad subscription will end. Then I 'll try NYM. And finally I will conclude in one of these 2, unless I find another option to test. With Mullvad, I don't have a speed limitation so far, I am more than good with it. In terms of privacy, as I said I paid with XMR, using TOR browser, without an email registration and essentially I am "unknown".
