thanks for you reply, I have read that page but unfortunately does not clear up anything of what we are questioning.

That page says basically 3 things:
1. the project is not jbg dependent
2. the project is actively developed
3. jbg is legit because Gandalf86 knows him for long

I think these statements are inaccurate because:
1. if jbg leaves, this project is very likely to die, if it's not dead already. As jbg also said (but it's an excuse to me), one reason of the lack of work is that he needed time to learn the code base (you definitely need time to learn a code base, but definitely not 7 months, which are the months of missing development from github). If this is true, I would expect a new developer to take months to learn the code base too, in the best case scenario. Developers are not robots or machines, you don't just replace them and expect that everything will be exactly the same. You are already very late with your road-map, you will be more late if jbg leaves, and you'll lose more investors and the competition will go ahead more in the meanwhile.
2. This is false until contrary proof. Again only 2 months of work in github out of 9. The points also are a bit ridiculous. One of them says that the 0 balance bug is a race condition. The 0 balance bug is an UI issue, race condition?! Also the 0 balance bug is not fixed yet, it's still happening to some users with the latest version! I would love to see the commit that jbg did to fix this, as I can't find it. At this point, I wouldn't be too surprised if it's not there at all.
3. if jbg fooled you for long, it does not make him more legit.

You need to understand that you're not investing in tech when you invest in this coin, you're investing in your trust on jbg and all the claims he does, claims that cannot be proved. He also has been proved as a liar, a bad project manager and a bad communicator. Good developers are usually good also at communicating, estimating and managing projects, that's why they then become project leads and mentors.
