But it also has little things that suck about it too.
Like how hard could it be to but the 2FA pgp message in a text box, so you can press Ctrl-A, Ctrl-C like the other sane markets namely Hansa and DHL.

The wallet system is actual AIDS and was designed for exit scamming.
Plus with the recent steady increase in transaction fees it just costs more over all.
