Hmm Interesting, Good volume and marketcap too for something like this but looks like the ROI was really bad since deflationary token was supposed to make the price was stable by reducing the supply for every transaction it's not it? Well still curious if there an real use case token that have this scheme.
I think its good to keep them in your portfolio. So far there only use case is that they are burned in every transaction. With time more use cases will pop up. Lets wait for a while
