This coin has no substance, I have been monitoring its progress the past year, and the team are not very sociable and clear with the direction of the project. I would stay away from kb3 many hodlers got burnt holding it in the beginning of 2018 its a real shame how its ended like this.
While I agree that the Team has been playing their cards close to their chest, I believe if you listen to the community meeting recordings you will hear their reasons for doing that and are in the best interest of those who are holding B3. As far as the direction of the project, though, what they are working on clearly stated (again, directly from Team leads Habaner0, Kdog, and Josh) are fixes to the node system, core updates to the wallet, and a DEX. It is taking time for two reasons - First, they are not just copying and pasting another project's code and labling it the B3 DEX ... they are working it from the bottom up. Second, they are doing it on a volunteer basis with no development funds ... this means everyone still needs to keep their day jobs and support themselves and their families while working on B3 in their spare time. Of course this second reason is not ideal, but to me it shows a level of commitment to the project that is encouraging.
I grant you, this type of bootstrap venture is not for everyone, nor is it something anyone is suggesting you should go all in on, but for me my relatively small investment in B3 Coin has secured me a nice position that I am happy to hold for now.
I bought in 2017. I would say those who feel they got burned in 2018 perhaps were not paying attention in High School history class and so did not understand what hyper inflation caused by 10,000% returns would mean. They obviously bought the coin because of the hype brought about by that promotion period, and not because of any features of the coin or promise that they held ... because those features are still here and are still promising, and are the reason I held past the end of 10k%, past each and every problem point B3 has lived through, and occasionally buy more.
It may work ... it may not ... if you are looking for guarantees you are going to be searching for a long time. Frankly, I thought we would be a whole lot further down the road to mass adoption by now, but governments are kicking and screaming enough that who knows if I'll see that in my lifetime. No matter ... but in my opinion, B3 has not "ended" until there is no longer anyone working to make something of it.
Everyone has to make their own decisions ... but there you are.
