Is NGC trusted?

I've been hearing a lot about NGC recently, and I'm considering using their services for my cryptocurrency transactions. However, I'm a bit hesitant as I've heard mixed reviews about their trustworthiness. So, I'm wondering, is NGC really a trusted and reliable platform for cryptocurrency transactions? What measures have they taken to ensure the safety and security of their users' funds? And are there any red flags or potential risks that I should be aware of before using their services?
