Chinese AI project on NEO blockchain that is allegedly implicitly backed by the chinese government. Couldn't find much that is negative about the project, except maybe this post on r/cryptocurrency that is quite technical: https://www.reddit.com/r/CryptoCurrency/comments/7od7vg/deep_brain_chain_dbc_is_vaporware_and_heres_why/.
A lot of the criticism in that post was however nuanced in updates of the post, admitted by the author.
Another pain point, although not related to the project itself, might be the fact that it is very low ranked on Coinmarketcap and has a relatively low volume. High risk should be assumed from an investor perspective. Things that I do like are the coinmetrics from the ICO: hardcap was "only" $12m, which wasn't excessive compared to many other ICOs.
A relatively small percentage of coins went to the team (10%) and 50% of total supply will be generated by mining. Transparency and a long period of unlocking team and foundation tokens: 10% per year over 10 years (predictable inflation) - source: whitepaper.
It makes the project seem more legit because of a less greedy approach in the ICO. So eventhough I have some reservations on the matter if this is a good investment with a reasonable profit expectation, I do not think that this is an outright scam. Before really investing in this project I think it is really important to be able to really understand the technical implications of this project before you can make a justifiable investment decision on a fundamental basis.
