fisrt of all i dont see many updates on ongoing developement while i bet the team does many things. bitcointalk doesnt count try to find anything interesing in this post exept bounty problems. its not very informative so would love to link soemthing like weekly updates f.ex. in my community.
There are as many updates as on any almost other coin. There's been announcements of the partnerships I mentioned, another one with an exchange I'd forgotten about, they posted something about the mobile wallet not that long ago. In nearly 3 years of being involved with altcoins I can only remember ever seeing one that had weekly development updates (Lisk), so you can't expect that kind of thing if it doesn't fit with the way they work.
I think you are really impatient for the price to rise so you can sell for profit, not for development updates, and that's not within the control of the Antshares team.
