I find scary someone invested on an instamined coin (DRK)
That's a bit uncalled for.
Many $millions have changed hands since January, what is left are people working hard to deliver a working privacy solution based on bitcoin codebase.
I'm sure BitFinex and many others would have done their homework before exposing their clients to DRK.
I don't know if that's uncalled for or not, but I'm pretty sure BitFinex care a lot more about getting money to themselves than the chance of exposing clients to risk. Why would they care about that?
First off, I invested in Darkcoin, then mined it for a while. So I'm one of the 'scary someone invested....' people, so I didn't take too kindly to that.
BitFinex took a lot of flack from its customers when they pre-announced the addition of DRK. They maybe in it for the money, but they also wouldn't want to lose existing trade. Unlike Mintpal and others who go for volume of coins, BitFinex don't, so they wouldn't walk into a project that had problems and didn't have prospects based on a dedicated team.
The same for vault of satoshi when they were first looking to integrate DRK <> USD. They had a good look around too.
