Valorbit might be delisted in exchangers before the dev make an updates.
Do you think the dev is that stupid of not being aware of such scenario? I do not think so, there are still some plans for valorbit to be included on other exchanges. There is an ongoing roadmap,as of now its the process of making a wallet for android gadgets and then IOS. Also try to think that the dev has some real life stuff that needs to take care of , he has a job and he does make some updates when he has some spare time. That is how I see it, most developers fall in this kind of routine.
