is BlackHalo even working ? or just a Shtick ?
edit: i would really like to invest and buy good amount, but its too scary
1. yes it is working
2. why?
1. i once tried to run blackhalo and it didn't work. maybe i didn't run it correctly...
I will try again and report
is it suppose to be marketplace+smart contracts ? i didn't find the source code of blackhalo, only binaries... should opensource it for trusting it.
2. scary because it is always scary to invest big in something

high risk to lose a lot. or gain a lot
I do like this coin since start because of the way rat4 managed the perfect launch, and other technical issues. and his code so good. but still i never invested alot
1. BlackHalo is not OpenSource (yet), i am not sure what exactly davids plans are in that regard. As soon as only the idea had been announced back then, scam coins which promised everything Halo could do were "produced" and I think he feared that all his work would just be copied/stolen in order to scam people. The "trust issue" with closed source is a problem I see too, though.
Maybe you should as david via our subreddit, i am sure he will address your concerns.
2. That goes basically for everything where money is involved, only advice is: better be careful and never risk what you cannot afford to lose completely. You never know what will happen, not many expected BLK to be "dumped" as it has been, but again that goes for almost everything in crypto. Not many people would have expected LTC to hit 1.30 USD or BTC to hit the 160,- USD range again as well....
