- 10$
I don't use Dtube myself, and only go occasionally to watch a music or drone video, but I'd wear a Dtube T-shirt to help promote STEEM.
I chose $10, not knowing what monetary system we're talking about, as the top end that I would be willing to spend on a shirt. It would have to be a really nice and fancy shirt to go above that, especially if there's any kind of taxes or shipping charges involved.
