Well I guess this goes to show you that no amount of research on a project can determine the turn of event at the end of the day,
Personally I don't see anything to be disappointed about, everything about listing a project in exchange is not an easy process, maybe there where conditions which they were unable to meet which lead to this, or they don't have the funds to sustain such listing at present, lots of reasons involved,
And as for hypes it is part of crypto, you should already know that by now, project will always come up with something to draw investors and supporters attention, it is nothing new, between they must have thought it through before considering a list on consbit, this is just a start, more exchange will come in near future.
