I remember ZIL but it seems that it is out of hand right now and the popularity of it that has it gained before wasn't taken cared of by the devs.
I may not agree with what you said since the Dev are doing their best in some areas that have to do with upgrades in service and mechanism.
I believe what the project lacks is marketing and crypto community engagement.
I may be wrong but that's what it is and you said what they really lack of. But it all ends up to I say that the devs haven't seen that part to maintain their position in the market.
But maybe this time, they'll look at that part to see that they need to engage a lot with their communities because if they do that. A lot of free marketing will be done towards them.
there are team that silently acting towards their upgrade or updates but we must remember that engaging to the community and the whole crypto world is the most effective way to gain investors and supporters.
what is the sense of working when after the upgrade you already lose your supporters because of lack of activities .
you are correct in this part and the ZIL team must act accordingly if they truly wanted to stay longer in this market.
