I just listened to this podcast
http://letstalkbitcoin.com/blog/post/lets-talk-bitcoin-156-the-moolah-storyIt tells the story about how Moolah and Mintpal were run and created by a scam artist.
A few people tried to say it was a scam but were screamed at and trolled endlessly by people that invested and thought they were going to make money off from it. Many of these people defending Moolah probably honestly believed in it. Had they know it was a scam, they wouldn't have invested in the first place.
I don't own any Bitshares, but I have followed it for 9 months and in that time have watched as time after time the plan for Bitshares has changed and things haven't happened as planned.
And now this thread reads just like the podcast states happened for Moolah.
It may or may not be a scam. I don't know, but there is definitely "some writing on the wall" of things not going right.
I'll admit the concept seems kind of neat, but this exact Bitshares platform has enough questionable factors in it for me not to invest.
For me, I am going to take the long approach of wait and see. If I come back in a year or two and things are great, I'll be convinced it is good.
My experience shows that if it is not legitimate, it won't last two years for sure.
