Mark my words, all they do with blockchain is waiting for delisting. After it you are getting your DTB exchanged for their emeralds bullshit in app balance and "sorry for any inconvenience". This shit game will only exist with in app purchases.
3- high hopes for new version, turn based "Final Fantasy" style, is definitely a good option. "Neon District" are going to do amazing with their turn based system. So fingers crossed.
