Actually the no devs and no mining aspect is what makes this an interesting coin to me.  With a key drive of cryptocurrency being decentralization I find it interesting that most of the time we (me included) gravitate to coins with more active "masters" and stake holders.  We get excited with news of mainstream companies buying into their technology and services despite those services having nothing to do with the value of the coin.  Take Ripple (and I have quite a bit).  Despite its blockchain technology having practical applications for financial institutions and their international operations, that application and it's success has nothing to do with the value of the ripple coin.  Ripple has only increased in parallel with our enthusiasm and faith that the Ripple enterprise will be successful.  Not to harp on Ripple but it makes my point better than most other coins in comparison because it is centralized.  Ripple controls it completely.  Rimbit however is out there in finite numbers without any mining consortium having any more advantage to acquire them than anyone else.  It doesn't matter if the original developer profited greatly from this project as most do.  It's not his anymore.  He, like us, will only ever be able to sell RBT for what someone is willing to pay and in turn can only buy it at a price RBT holders are willing to accept.  That simplicity is itself valuable since it's not convoluted with the promises of "big things to come" and momentous "dev announcements" etc.
