Even though I cannot substantiate this line of thought, I really feel it has something to do with the authorities. The closure was sudden considering that they rarely even started. Every business takes sometimes to become profitable and a business of this magnitude should have envisaged some challenges at the beginning if there were no external factors at play here. So my best guess is that they ran into problems with the authorities which might have made the investors incur some losses in a business that is just getting started.
There is no conspiracy theory here. Its just that our investor had financial difficulties, this is not related to the project, but due to family circumstances of our investor. Therefore, we spoke honestly about this and suspended work a few days ago.
Life is a challenge and any unforeseen circumstance could happen at any time, so I quote understand you even if many do not. I wonder how someone will establish an exchange with as little risk attached as yours and abandon it altogether without trying to patch things up (even with manageable challenges) if there are truly no overwhelming reasons for that. This is sincerity I see and it is better than paying "Paul with Peter's money.
I wish your investors' family a speedy financial recovery and don't forget to resume here if everything is solved.

Their topic was created on May 30, they are gone already and they didn't post a single explanation about closing their business:

I won't judge anyone by the general occurrence or at least what people perceive to be so. Nevertheless, do you view any reason on sight? Regulation?
